Radiation therapy is the most safest and effective choice of cancer treatment today,only because of the IGRT, This information will help you prepare for image-guided radiation therapy (IGRT). It will help you know what to expect before, during, and after your treatment. You will also learn about side effects and how to care for yourself during your treatment. Read through this resource before you start radiation therapy. Use it as a reference in the days leading up to your treatments so that you can prepare as much as possible. Bring this resource to your simulation appointment and all future appointments with your radiation oncologist. You and your healthcare team will refer to it throughout your treatment.

摘要
以目前診斷食道腫瘤的技術來說 是由醫生對病患的頸胸部影像來判斷是否有腫瘤的存在，
，
進而判斷為惡性或良性腫瘤，其過程則需要花費許多的人力在判讀病患的胸部影像切片上，不僅
耗時又耗力，因此本專題目的在於能利用電腦判讀正子放射斷層攝影（Positron Emission
，偵測腫瘤的存在並將其定位，以協助醫生進行後續的治療。此專案又分為
Tomography，PET）
兩個部分：分析 PET 切片影像和切片 3D 重建。
第一部分：腫瘤物件輪廓偵測。因大多數惡性腫瘤對葡萄糖的代謝會異常增加，所以在 PET
影像中，除了腦部、腎臟、等等代謝旺盛的器官之外，惡性腫瘤也會呈現較深色的部分，加上外
形接近橢圓，因此本專題利用這兩個特徵圈出腫瘤的可能性位置。下圖為 PET 縱切食道癌影像，
紅色箭頭指的地方為腫瘤。
第二部分：重建 3D 模型，則是利用國家高速網路與計算中心所研發出來的 3D 醫學影像處理
軟體－Medical Image Illustrator(Miil)，將分析過的 PET 影像做 3D 的合成，方便做治療追蹤及提
供醫師手術前之模擬。
