Ultrasonic temperature phantom without simulation of thermal properties of actual human body

摘要

A method was proposed to demonstrate the formation of ultrasonic temperature phantom without simulation of thermal properties of actual human body. feature of the proposed method revealed that temperature phantom itself was performed without the need for initiating the thermal properties of an actual human body. The temperature measurement using the new method was performed by converting the time and the temperature axes using the thermal properties of the phantom and the human body. The principles of the proposed phantom were considered where the temperature rose the case of a one-dimensional model, as functions of time, t, and position, x, in a material that was expressed by using the following complementary error function. A numerical calculation was also performed by the finite difference time domain (FDTD) method to check whether the proposed method was appropriate for the two-dimensional model.
