摘要

幾十年來由國內外研究報告證實，高溫腫瘤治療方法已經成為有效治療癌症或惡性腫瘤方法之ㄧ。利用超音波具有波長短、穿透力強特性，作為高溫腫瘤治療之加熱工具。可以針對不同深度及形狀腫瘤進行有效加熱治療。本研究乃針對各式超音波換能器所產生的超音波波壓分佈進行數值分析，並探討應用於高溫腫瘤治療（hyperthermia）上的可行性。
本研究除了數值分析超音波換能器所放射的波壓分佈外，也將製作超音波換能器並實際量測其波壓分布情形。利用AIMS（Acoustic Intensity Measurement System）測量換能器之波壓分佈並與電腦模擬結果進行比對，結果可以提供有用資訊從事超音波高溫腫瘤治療用的超音波換能器設計。

Within recent decades, results have shown that hyperthermia is one of the effective methods treating of cancers or malignant tumors. Ultrasound has several characteristics, such as, small wavelength, deep penetration, which make it well suited for hyperthermia. A well-designed ultrasound transducer can effectively treat tumors at different depth and size. First, the acoustic pressure fields emitted by different ultrasound transducers are calculated numerically, and investigate their application in hyperthermia.
Second, several ultrasound transducers are fabricated to measure their acoustic pressure fields. We use AIMS (Acoustic Intensity Measurement System） to measure the acoustic pressure field. The measured acoustic pressure fields are compared to those fields calculated theoretically. Results will provide us with useful information to design a good ultrasound transducer for ultrasound hyperthermia.
