電気・超音波マルチイメージングシステムにおけるインピーダンスイメージングの精度向上

抄録

The purpose of this study is to make a proposal for a simple and non-invasive irradiation positioning technique in the heavy particle beam therapy. For this purpose, we propose a method of using electric and ultrasonic multi imaging. Features of the proposed method, by simultaneous imaging of ultrasound and electric characteristics in the same space, with only ultrasound imaging is that changes in can not be found properties will be able to discover. This paper attempts to imaging of the tumor area by computer simulation in the model close to a living body. Furthermore, the diagnostic ultrasound system estimating the structure of the body, proposes a method of setting the initial value of the impedance imaging tailored to its composition, we report confirmed its usefulness.
