中文摘要 癌症治療方法一直是人類很關注的一大問題,許多治療方式都會帶來嚴重的後遺症。電磁熱治療的原理是利用高頻感應加熱器產生交變磁場,使得金屬導體內部升溫,進而燒灼腫瘤細胞,達到治療之目的。本論文是研究感應線圈產生的磁場對腫瘤細胞內針具的加熱效果做比較,希望電磁熱治療的加熱深度可以達到更深,故設計可撓式線圈取代傳統硬式線圈,且可撓式線圈可依不同治療部位而自由變換其線圈大小,比傳統硬式線圈在其應用上方便許多。利用數值模擬軟體對兩種線圈進行磁場及感應熱的分析,因可撓式線圈磁場深度的定義為線圈邊緣往線圈中心的距離,在兩種線圈直徑大小及深度大小相同的情況下,可撓式線圈對針具的加熱效果比硬式線圈來的好,進而對組織內針具加熱時之燒灼面積做探討及分析。
英文摘要 Cancer treatment has been a major concern of human beings, and numerous treatments cause severe sequelae. In contrast, electromagnetic thermal treatment yields relatively few side effects. This method involves using a high-frequency induction heater to generate alternating magnetic fields, which increases the internal temperature of metal conductors. The heated conductors are used to ablate tumor cells for therapy. This study compared the heating effects of induction coil-generated magnetic fields on the needles inside tumor cells. The purpose was to explore the possibility of enhancing the heating depth of electromagnetic thermal treatment. Because flexible laminated copper coils are easy to use and adjustable for efficiently treating specific body parts, they were used to replace conventional hard coils. Numerical simulation was employed to analyze and compare the magnetic fields and induction heat generated by the two types of coils. The magnetic field depth generated by flexible laminated copper coils is defined as the distance between the coil edge and coil center. When coil diameters and magnetic field depths were identical, the flexible laminated copper coils generated a better heating effect on the needles than the hard coils. The ablation areas resulting from inserting heated needles into tissues were studied.
