- W3200764841 abstract "In recent years, electromagnetic wave hyperthermia and high intensity focused ultrasound (HIFU) treatment have been used as non-invasive tumor treatment methods. HIFU is a treatment method that cauterizes a tumor by focusing ultrasound waves from the outside of human body to a single point and raises the temperature near the focal point to a temperature of approximately 70 ° C or higher. On the other hand, electromagnetic wave hyperthermia is a method of treating cancerous tissues with electromagnetic wave power from 42 to 43 ° C for a certain period of time. Electromagnetic wave hyperthermia has a risk of undesirable heating near the electrodes. Since HIFU is done at high temperature, there is a risk of cauterizing healthy tissue. In addition, tissues with high acoustic impedance such as bones exist inside the human body, and ultrasound waves will be reflected and scattered. In this study, we focused on ultrasound hyperthermia which has the advantages of both of these treatment methods. In the proposed ultrasound hyperthermia treatment method, multiple transducers are used to superimpose ultrasound waves to heat the targeted area. As ultrasound waves are superimposed from multiple directions, the output of one transducer is low, and it is thought that abnormal heating unlikely occurs near the ultrasound source. Therefore, it is thought that the proposed method can be performed safely compared to HIFU and electromagnetic wave hyperthermia. In addition, in order to heat the affected area with ultrasound waves, it is necessary to irradiate the affected area linearly without diffusing the ultrasound waves. In the present study, a cylindrical acrylic guide was attached at the tip of the transducer, and the change of ultrasound intensity was examined with computer simulations and experiments. In the experiments, as shown in Figure 1 , a transducer with an acrylic guide was placed inside a water tank and moved by 0.5mm along the X direction to measure the ultrasound intensity. We also performed similar simulations and compared both results. From the computer simulations, the maximum sound pressure values were 300[MPa] without and 660[MPa] with the acrylic guide. Therefore, it can be seen that ultrasound intensity is about doubled when the guide is provided. In the experiments, the ultrasound intensity was 1.2[mV] without and 2.3[mV] with the guide, also it can be seen that the ultrasound intensity is approximately doubled. From these results, it was confirmed that the ultrasound intensity was high when using the acrylic guide. As a result, it is considered that by attaching an acrylic guide, ultrasound waves are irradiated linearly without diffusing, and it is possible to effectively heat the affected area. We are working on conducting experiments and simulations when ultrasound waves are superimposed using multiple transducers, and examining the results." @default.
