摘要

隨著近年來癌症逐漸成為現代人健康威脅的主要因素之一，癌症的治療也需要針對病患的各種病因，身心狀況來對病患進行更有效率的治療，其治療方式的發展也不再只僅限於手術，化療等副作用較多且需要一連串療程之傳統方式。有效且副作用少的熱療法(hyperthermia)即為現今的癌症臨床實驗療法的重要發展方向之一。 在此我們所提到的熱療方式是利用電磁感應在鐵磁性材料所產生之熱能來殺死癌細胞。而已知的加熱線圈結構到目前為止，對如何在某一範圍加強其磁場以產生足夠的熱能，都需要更進一步的研究。本篇論文對於過去所使用熱療儀器的線圈結構的磁場產生效率做了有效的改進並加以研究，如磁路的觀念，和多組線圈的架構。我們於此篇論文中提供了利用CST EM STUDIO 的磁場模擬磁路的磁場產生情形，將amorphous 材料應用於磁路的製作上並於實驗中量測其磁場得到的結果做比較，將目前已實際用於醫療的針灸針至於猪肝上做實際的加熱測試，以及多線圈系統的設計，我們以上的研究成果將能使得加熱線圈的磁場產生效率得到進一步的改良。

Since cancer became the leading causes of human death recently, the
effectiveness of cancer treatments should also have to be developed. The cancer
treatments under development are not just limited on surgery and chemotherapy
which are traditional treatments with serious side effects. Hyperthermia is also one of the important developing clinical treatments.
The hyperthermia is use the inductive heat to kill cancer cells. So far the coilstructures which were presented before still need more development to bein use.This thesis provides our research to improve the efficiency of the coil structure, like concept of magnetic circuits and design of multi-coil structure. We use CST EM STUDIO software to simulate the magnetic flux density distribution, put the magnetic material, amorphous, in use of our magnetic circuit, measure the actual magnetic flux density distribution, measure the temperature of the handy acupuncture needles on piece of pig’s liver after the experiments, and consider the multi-coil system design. The results of our research will make the efficiency of induction heating coils be improved.
