10TH INTERNATIONAL SYMPOSIUM ON THERAPEUTIC ULTRASOUND (ISTU 2010) | 2011

The Effect of the Elastic Body assumption on the Focusing of Ultrasounds in Inhomogeneous Media

Takaaki Shimura; Kohei Okita; Shu Takagi; Yoichiro Matsumoto

Simulation of HIFU transmission in the human body is a useful method for High Intensity Focused Ultrasound (HIFU) treatments. For HIFU simulation, it is important to establish a calculation system which can incorporate inhomogeneous media such as human cells, bones, and organs. In this research, we have assumed a linear elastic body for bones and organs, and constructed a fluid‐elastic coupled calculation code. We used the FDTD method for calculation. As a result, we have found the difference in HIFU transmission between elastic and fluid models.
