  • GS0204 Basic Study of Ultrasonic Wave Propagation by Using Computer Simulation, MIURA Eitaro, MIYAZAWA Takato, SHINDO Yasuhiro, KATO Kazuo, 日本機械学会関東支部総会講演会講演論文集, 2016, (22) "GS0204 - 1"-"GS0204-2",   2016 03 10 , High Intensity Focused Ultrasound (HIFU) was developed for treating tumors non-invasively. In this treatment, ultrasound is focused on the target inside the body and ablates cancerous tissues. Small size HIFU devices have been developed, because large size HIFU devices are expensive for using at a private hospital. However, the small size HIFU uses also small transducers, there is a disadvantage that the focal distance is short. In this study, we proposed a method to control the heated area for the tumor location. First, we presented a ring-shaped transducer model with the spherical auxiliary vibration plate. Second, we calculated pressure distributions from computer simulation using the Finite-Difference Time-Domain (FDTD) method. From these results, we found that the proposed control method was useful for effective HIFU treatments.

  • 1B33 Analysis of Temperature Distribution Using Resonant Cavity Applicator with Adjustable Electromagnetic Shield, MATSUSHITA Takuma, ISEKI Yuya, SHINDO Yasuhiro, TAKAHASHI Kenji, KATO Kazuo, バイオエンジニアリング講演会講演論文集, 2016, (28) "1B33 - 1"-"1B33-4",   2016 01 09 , This paper describes a new heating method for treating osteoarthritis (OA) inside a knee using a resonant cavity applicator. OA is a common musculoskeletal disorder that causes pain, stiffness, swelling, and loss of function in a joint. As the disease progresses, the inflamed synovium invades and damages the cartilage and bone of the joint. In clinics, there are several treatments for OA, for example, surgical operation, thermal therapy, and chemotherapy. Physical methods, such as thermal therapy, with hot packs, paraffin baths, ultra-short waves, infrared lamps and microwave diathermy system are widely used for musculoskeletal disorders in the clinic. However, the skin penetration depth of these methods is less than approximately 20 mm. It is not easy to heat the affected part of the human knee. For an effective treatment of osteoarthritis, the deep seated joint cavity region in the human knee must be heated between approximately 36 and 38 ℃. In the previous study, a resonant cavity applicator for thermal therapy of OA was proposed. In this study, we proposed a new heating method using a resonant cavity applicator with adjustable electromagnetic shield. From the estimated results, it was found that the proposed heating method is able to heat the deep tissue with the leg in a bent position.

In this treatment, ultrasound is irradiated from outside the body part to be focused on the target in the body, and kill cancerous tissue by thermal energy generated at the focal point. However, in order to carry out the treatment at a high temperature, there is a possibility that cauterizing also the normal tissue surrounding the tumor. Also, small HIFU devices have been developed, because large HIFU device expensive and large. But, so transducers are used to it is small, there is a disadvantage that its focal distance is short. In this study, we propose a control method of heating position with the vibration plate shape. Here, we propose the heating position control method of treatment according to the tumor location First, we presented a ring-shaped transducer model with the vibration plate for computer simulations. Second, we calculated pressure distributions from computer simulation using the Finite-Difference Time-Domain (FDTD) method. From these results, we found that the proposed control method was useful for HIFU.

In our previous study, we reconstructed a 3-D model from a 2-D ultrasound images to detect the location and size of the target and to calculate temperature distributions inside the 3-D model. From the results of computer simulations, we estimated the suitable condition for heating target efficiently. In the present paper, first, we performed heating experiments of the agar phantom using the suitable condition for heating target efficiently. Second, a comparison of the estimated temperature and estimated temperature was presented. From these result, we found that the proposed system is useful for effective hyperthermia treatments.

  • Heating Properties of Resonant Cavity Applicator for Treatment of Osteoarthritis:- Temperature Distributions Calculated by 3-D FEM -, SHINDO YASUHIRO, WATANABE KAZUKI, ISEKI YUYA, KATO KAZUO, KUROSAKI HIROMASA, TAKAHASHI KENJI, Thermal Medicine(Japanese Journal of Hyperthermic Oncology), 30, (1) 1 - 12,   2014 , Abstract : This paper describes the heating properties of the resonant cavity applicator for treatment of osteoarthritis inside the knee joint. Thermotherapy is widely used for musculoskeletal disorders as a physical therapy in the clinic. Hot packs, paraffin baths, microwaves and heating devices with ultra-short waves are generally used, as well as therapeutic exercises for joint such as osteoarthritis. These methods are easy, simple and effective in inhibiting osteoarthritis progression at the early stage. However, it is not easy to heat the deep tissue by using these methods. Therefore, a successful thermotherapy for osteoarthritis has not yet been realized.
    To overcome these problems, we proposed a new heating method using the resonant cavity applicator for osteoarthritis. In this new heating method, a human knee is placed between two inner electrodes. Two cylindrical metal shields are used to protect the leg from the electromagnetic energy, but the knee is uncovered to focus the heating energy on the diseased joint. The human knee is non-invasively heated with electromagnetic fields stimulated inside the cavity.
    In the present paper, first, a method of constructing a three-dimensional (3-D) anatomical human knee model from two-dimensional (2-D) medical images for calculating temperature distributions is described. Second, temperature distributions using the finite element method (FEM) for several therapeutic heating methods used in the clinic are presented. Third, comparisons of the calculated temperature distributions during osteoarthritis treatments are discussed.
    From these results, it was found that proposed heating method using the resonant cavity applicator is useful for treatment of osteoarthritis inside the knee joint.

  • A Support System in Virtual Reality for Effective Hyperthermia Treatments: Heating Properties of Needle Applicator for Brain Tumors, SHINDO Yasuhiro, YASUHIRO SHINDO, YUYA ISEKI, KAZUYA NAKANE, NAOKI MIMOTO, MITSUNORI KUBO, KAZUO KATO, HIDEAKI TAKAHASHI, TAKEO UZUKA and YUKIHIKO FUJII, Thermal Medicine, 27, (3) 79 - 87,   2011 09 20 , This paper describes the effectiveness of the developed simulator system for performing an effective hyperthermia treatment with a needle applicator in virtual reality (VR). The human brain is protected by the skull, which makes it difficult to non-invasively heat deep brain tumors with electromagnetic energy. Generally, needle applicators were used in clinical practice to heat brain tumors. However, some problems exist. One is that this heating method has a small heating area around the needle. In order to expand the heating area of a needle applicator, we developed a new type of needle applicator made from a shape memory alloy (SMA). The thermal properties of the SMA were checked experimentally using the developed heating system. As a result, the proposed needle applicator made of SMA is useful to create a wider heating area inside a tumor.
    Another problem is that medical doctors find it difficult to put a needle applicator into a target point inside of tumors. Therefore, a support system for performing an effective hyperthermia treatment is required in the clinic.
    In this paper, first, we constructed an anatomical 3-D model from magnetic resonance imaging (MRI) and X-ray computed tomography (CT) images by using 3-D computer aided design (CAD) software.
    Second, we presented the finite element method (FEM) model which is divided into non-linear elements on 3-D computer graphics (CG).
    Finally, we calculated temperature distributions using the 3-D FEM model with blood perfusion during hyperthermia treatments.
    From these results, it was found that the proposed VR system is effective for performing hyperthermia treatments.

  • 20704 Basic Study of Focused Ultrasound Heating System with Simple Model by Using FDTD Method, MIYAZAWA Takato, SHINDO Yasuhiro, KATO Kazuo, CHOI Pak-Kon, TAKEUCHI Akira, 日本機械学会関東支部総会講演会講演論文集, 2015, (21) "20704 - 1"-"20704-2",   2015 03 20 , In the clinic, High Intensity Focused Ultrasound (HIFU) is used to non-invasive treatments for cancers. However, it is not easy to rapidly monitor temperature elevations which reach higher than 60℃ and may cause undesirable thermal injuries. On the other hand, hyperthermia treatment is based on the clinical fact that cancer cells are more weaker than healthy cells hi the temperature range of 42-43℃. In this study, we propose a new type of transducer for hyperthermia treatments with focused ultrasound heating energy to expand the heating area. First, we presented a new type of transducer model for computer simulations. Next, we calculated pressure distributions using a Finite-Difference Time-Domain (FDTD) method with the proposed transducer model. From these results, it was found that the proposed transducer was useful for hyperthermia treatments.
  • 20705 Supporting Simulator System in a VR for Effective Hyperthermia Treatment with Needle Applicator, WATANABE Shunichiro, ISEKI Yuya, SHINDO Yasuhiro, KATO Kazuo, 日本機械学会関東支部総会講演会講演論文集, 2015, (21) "20705 - 1"-"20705-2",   2015 03 20 , We proposed the developed simulator system for an effective hyperthermia treatment with needle applicators in a virtual reality (VR). Medical doctors used needle applicators to heat brain tumors, but this method has some problems. As needle applicators have a small heating area, it is not easy to precisely put a needle into a target point for medical doctors. So, a VR simulator system for effective hyperthermia treatments is required in the clinic. In this paper, first, we proposed the developed simulator system in VR for effective hyperthermia treatments with needle applicators. Second, we performed to put the needle applicator into the agar phantom model in VR using the developed simulator. From these results, it was found that the developed simulator system is useful for performing effective hyperthermia treatments.

The blood flow rate is needed for calculating the temperature distribution during hyperthermia treatments. In previous study, the mean rate of blood flow through human tissue was used hi the conventional method with FEM. However, the accuracy of the calculated temperature distribution around a large blood vessel was not so high. In this study, first, we reconstructed a 3-D anatomical FEM model from 2-D medical images using a 3-D CAD software. Second, we calculated temperature distributions with a 3-D anatomical human head model by solving the bio-heat transfer equation. Furthermore, a comparison of the temperature distributions when considering the blood vessel was discussed. From these results, it was found that temperature estimation during hyperthermia treatments with the cooling effect of blood perfusion is required.

We estimated the temperature distribution inside an agar phantom using the finite element method (FEM). Used magnetic nanoparticles were magnetite (Fe_3O_4) and yttrium (Y_3Fe_5O_<12>). Here, first, the electrical properties of agar phantoms mixed with magnetic nanoparticles were presented. Second, the results of heating these agar phantoms obtained by computer simulations and heating experiments were presented. Third, a comparison of these results was discussed. Finally, from these results, the temperature rise of agar phantoms mixed with magnetic nanoparticles was not sufficient for effective hyperthermia treatments.
  • 20711 Basic study of MRI image processing for extracting tissue outlines, Anan Daisuke, Nakamura Keito, Iseki Yuya, Shindo Yasuhiro, Kato Kazuo, 日本機械学会関東支部総会講演会講演論文集, 2015, (21) "20711 - 1"-"20711-2",   2015 03 20 , A resonant cavity applicator system for brain tumor hyperthermia treatments without contact was presented. To use this heating system in clinics, an accurate 3-D anatomical human model of a patient will be needed. However, this model was reconstructed by tracing outlines of tissues on the MRI and X-ray CT images. Therefore, it was not easy that this model is created correctly. So, the purpose of this study is to extract tissue outlines on the MRI image by using image processing. First, the algorithm of image processing was presented as a flowchart. Second, a comparison of original image and the image that was processed according to flowchart is discussed. From this result, it was confirmed that tissue outlines on MRI images can be extracted by using the proposed image processing.
  • 20712 Heating properties and stress distributions for effective thermal therapy for osteoarthritis during expansion of knee gap, MATSUSHITA Takuma, SHINDO Yasuhiro, 日本機械学会関東支部総会講演会講演論文集, 2015, (21) "20712 - 1"-"20712-2",   2015 03 20 , This paper describes the experimental results of new heating methods for treating osteoarthritis (OA) inside a knee using a resonant cavity applicator. OA is a common musculoskeletal disorder that causes pain, stiffness, swelling, and loss of function in a joint, hi the previous study, a resonant cavity applicator for thermal therapy of OA was proposed. Experimental results of temperature distributions when using the resonant cavity applicator and using microwave diathermy systems were discussed. However, a knee gap is very close when OA is progressing. It is not easy to heat the affected part of the human knee. For an effective treatment of OA, the deep seated joint cavity region in the human knee must be heated between approximately 36 and 38 ℃. In this study, a more useful method of resonant cavity applicator was developed for OA with keeping stress on leg to widen knee gap. From the results of computer simulations, it was found that the proposed heating method is useful for treating OA inside a knee joint.

We proposed a resonant cavity applicator with metal shields for preventing the edge effect on human abdominal regions. In this paper, first, we reconstructed a 3-D human abdominal model from ultrasonic images. Second, proposed heating method was described. Finally, from the results of specific absorption rate (SAR) distributions and temperature distributions using 3-D FEM, it was shown that the heated area inside a human abdomen could be controlled by changing the electromagnetic field distributions. From these results, it was found that the improved re-entrant resonant cavity applicator was useful for effective hyperthermia treatments.

Second, the results of computer simulations using the 3-D anatomical human head model were presented. Finally, from these results, it was concluded that the developed coaxial needle applicator is useful for hyperthermia treatments.
  • Basic Study of Monitoring System for Effective Hyperthermia Treatment, Nakamura Keito, Iseki Yuya, Shindo Yasuhiro, Kato Kazuo, IEICE technical report., 114, (482) 97 - 98,   2015 02 23 , We have proposed a resonant cavity applicator for hyperthermia treatments. This applicator does not have a monitoring system to detect the location and size of the target. To overcome this problem, we propose a monitoring system using a commercial diagnostic ultrasound imaging system. In the present paper, in order to show the validity of this system, first, a method of reconstructing a 3-D model from 2-D ultrasound images was presented. Second, a comparison of the estimated temperature and measured temperature was described.
  • Temperature estimation during hyperthermia treatments with mean blood flow and inside artery and vein, NAGASAWA Junichi, GOTO Syuya, ISEKI Yuya, SHINDO Yasuhiro, KATO Kazuo, IEICE technical report., 114, (482) 109 - 110,   2015 02 23 , This paper describes heating properties of a resonant cavity applicator for heating brain tumors calculated by a computational fluid dynamics (CFD) with blood perfusion inside blood vessels and mean blood flow rate. The blood flow rate is needed for calculating the temperature distribution during hyperthermia treatments. In previous study, the mean rate of blood flow through human tissue is used in the conventional method with Finite Element Method (FEM). However, the accuracy of the calculated temperature distribution around a thick vessel was not so high with this calculating method. In this study, temperature distributions around the artery and vein calculated by the CFD with mean blood flow rate during hyperthermia treatments with the cavity applicator are discussed. First, we described our heating method for treating deep brain tumors. Second, we calculated temperature distributions with the bio-heat transfer equation and heat-flow equation. From these results, we showed the effectiveness of this new calculating method for estimating the cooling effects of blood perfusion inside artery and vein with mean blood flow rate.

  • Development of Automatic Impedance Matching System for Resonant Cavity Applicator, SHINDO YASUHIRO, KATO KAZUO, TAKAHASHI HIDEAKI, UZUKA TAKEO, FUJII YUKIHIKO, Thermal Medicine(Japanese Journal of Hyperthermic Oncology), 26, (2) 63 - 74,   2010 , This paper describes a new system to match the impedance automatically for a re-entrant resonant cavity applicator during brain tumor hyperthermia treatments non-invasively. We have already discussed the effectiveness of the heating method using a manual impedance matching controller with heating experiments of an agar phantom and computer simulations. With this heating method, to generate heating power in the cavity, it is necessary to match the impedance and to tune the resonant frequency. In the initial prototype heating system, both were manually adjusted. However, it was difficult to match the impedance and to tune the frequency especially using a high resonant frequency.
    To overcome this problem, we developed the automatic impedance matching system (AIMS). It is known that reflected power is generated when the impedance matching is not complete. In this system, to reduce the reflected power which is fed back to the computer, the stepping motor to turn the dial of the variable capacitors is controlled by developed software. To evaluate the developed AIMS, the heating experiments of the agar phantom, using several electromagnetic modes, were performed. The VSWRs are 1.05 and 1.01 using manual matching and AIMS, respectively. From these results, we found that the temperature rise in the agar phantom using AIMS was about 180% (with TM012-like mode) and about 110% (with TM010-like mode) more than using the manual type controller under the same heating condition. It was found that the proposed system was very effective for hyperthermia treatment using the resonant cavity applicator even when the resonant frequency was high.

Since a human brain is protected by a skull, it is not easy to non-invasively heat deep brain tumors with electromagnetic energy for hyperthermia treatments. Generally, needle applicators were used in clinical practice to heat brain tumors. However in a clinic, it has some problems. One is that it is not easy to put a needle applicator into a target point for a medical doctor. So, a supporting system for performing an effective hyperthermia treatment is required in the clinic. In this paper, first, we presented the FEM model on 3-D computer graphics (CG). Finally, we calculated temperature distributions using the 3-D FEM model with blood perfusion. From these results, it was found that the proposed VR system is effective for performing hyperthermia treatments.

Two types of simple cylindrical models to discuss about thickness of CSF region were presented. From results of FEM analyses, we could confirm that pressure changes did not depend on the thickness of CSF. On the other hand, from results of impact experiments, we could confirm that pressure changes caused by a cavitation phenomenon depend on the thickness of CSF. From these results, we found that a contrecoup injury depends on the cavitation phenomenon.

Our heating system is composed of a large size resonant cavity applicator. In this heating method, a human body is placed between the two inner electrodes and is heated by electromagnetic fields stimulated in the cavity without contact between the surface of the human body and the applicator. However, the performance of this prototype system was not realized enough because an impedance couldn't be matched sufficiently. We refined the loop type antenna to stimulate electromagnetic fields effectively in the cavity and the experiment was performed with a cylindrical agar phantom. From the experimental heating results, it was found that it is possible to non-invasively heat the deep tumors in the abdominal region without contact with the developed heating system.

  • Heating Properties of Needle Applicator Made of Shape Memory Alloy for Brain Tumor Hyperthermia, KUBO MITSUNORI, MIMOTO NAOKI, KANAZAWA YOSHIHIRO, SHINDO YASUHIRO, KATO KAZUO, TAKAHASHI HIDEAKI, UZUKA TAKEO, FUJII YUKIHIKO, Thermal Medicine(Japanese Journal of Hyperthermic Oncology), 25, (3) 71 - 110,   2009 , This paper describes a new heating method used to expand the heating area of a needle applicator by using a needle applicator made of a shape memory alloy (SMA) for brain tumor hyperthermia treatment. The purpose of the study described here is to show the ability of the method to expand a defined heating region. One major disadvantage of RF interstitial hyperthermia treatment is that this heating method has a small heating area. To overcome this problem, a new type of needle made of a SMA was developed. The thermal properties of this proposed method, when applied to agar phantoms, were calculated with computer simulations and these properties were checked experimentally with the current physical version of the heating system. The calculated temperatures were in close agreement with the measured temperatures with an error of 10% or less. In both the numerical calculations and experimental results the proposed SMA needle heat treatment expanded the heating area to approximately 300% of that of a non-SMA needle heat treatment. These results suggest that the proposed heating method using the SMA needle applicator is capable of being used for invasive brain tumor hyperthermia treatments.

  • Heating Properties of a Resonant Cavity Applicator for Brain Tumor Hyperthermia: TM-like Modes Permit Heat Production without Physical Contact, YABUHARA TADAO, SHINDO YASUHIRO, KATO KAZUO, TAKAHASHI HIDEAKI, UZUKA TAKEO, FUJII YUKIHIKO, Thermal Medicine(Japanese Journal of Hyperthermic Oncology), 24, (4) 141 - 152,   2008 , This paper describes a potential new method to non-invasively heat a region in a human brain by using electromagnetic field patterns generated inside a resonant cavity and does not require any physical attachments to the subject. The purpose of the study described here is to demonstrate the ability of this method to heat a small defined region. This study utilized computer simulations and a current model of the new heating system. In this proposed heating method, a human head is placed in the gap of a re-entrant type resonant cavity. The brain tumor is heated through interactions with electromagnetic energy, and no contact is required between the surface of the head and the inner electrodes. The thermal properties of this proposed method when applied to agar phantoms were calculated with computer simulations, and these properties were checked experimentally with the current physical version of the heating system. The calculated temperatures were in close agreement with the measured temperatures with an error of 10% or less. The TM-like modes are similar to the transverse magnetic (TM) modes generated inside a cylinder type resonant cavity. To heat a defined region, two TM-like modes were tested on agar phantoms. The thermal images of the cylindrical agar and the agar head phantoms showed that the values for the temperature increases at the center of the heated agar phantoms using two modes, a TM010-like mode and a TM012-like mode, were 5.9°C and 8.0°C, respectively. The TM010-like mode resulted in a larger area being heated than the TM012-like mode. In experimental results, compared to the TM010-like mode, the heated area with the TM012-like mode was localized to approximately 50% of the area heated by the TM010-like mode. These results suggest that the proposed heating method using electromagnetic field patterns generated inside of a resonant cavity is capable of being used for non-invasive brain tumor hyperthermia treatments.
