摘要

本研究對腎臟摘除手術做模擬，當外科醫生面對高難度的腎切除手術時，模擬系統就成為一個有效的工具，可以事先讓醫生評估各種手術會發生的狀況以及相應的解決方法，進而提高手術的成功率，此模擬系統也可以應用在學生的手術教學上。
對於病患的容積資料，我們使用一動態Cube來記錄MC演算法所生成的三角片資訊，利用這些三角片的線性轉換來達到軟組織操作(如掀開)的目的。掀開軟組織後便可讓我們看到身體內部的器官，而將該器官與其他器官的連接部分切開，然後辨識其分離器官，並加以移除，掀開與移除的操作都使用Seed and Flood演算法。

In this study, the kidney removal surgery simulation, when surgeons face difficult nephrectomy, the simulation system has become an effective tool, surgeons can advance to assess the surgery situation will happen and the corresponding solutions, thus improvingsuccess rate of surgery. This simulation system can also be applied on the students to surgical teaching.
For Volume Data of patients, we use a dynamic data structure to record the reconstructed triangles in a cube by the MC algorithm. Use of a linear transformation of these triangles to achieve the soft tissue operation(as peeling). We can see the body's internal organs after peeling soft tissue, and cut off the connection part of organs and other organs. then identification of separated organs, and be removed. Peeling and removed operation both use Seed and Flood algorithm.
