In this thesis, ga is used to optimize the beam weights of intensity modulated radiation therapy ( imrt ) inverse planning, and 2d and 3d isodose contour as well as dose volume histogram ( dvh ) are used to evaluate the treatment plan
本文應用遺傳演算法優化逆向調強放療計劃中射束的權重,用二維等劑量線、三維劑量分佈和劑量體積直方圖來評估計劃的優劣。Study on factors to influence dose distribution in radioactive liquid - filled balloon
放射性液體球囊劑量分佈的影響因素探討The doctors can observe the relationship and geometry of the organs and the tumors, from the 3d model of the human body, which can help them create the therapy plan. the radiation dosimetry is built using monte carlo method. after we extract the iso - surfaces from the volume of the doses, the relationship between radiation doses and the cancer is represented on a 3d model, which is greatly helpful for the doctors to improve their therapy plan
通過建立三維人體模型,可以幫助醫生直觀的觀察人體內部病灶及組織器官的形態位置尺寸,並獲得其量化指標,從而更加準確的制定治療計劃:根據初步的放療計劃,使用montecarlo方法建立模擬的放射劑量分佈數據場,再通過等值面提取方法獲得等劑量面,顯示並量化劑量分佈情況和病灶(靶區)的關系;根據模擬的結果對放療計劃進行適當修改,並最終獲得最佳的放射治療計劃。According to geometrical focusing theory, the gamma knife can focus in spirals 30 beams of co - 60 gamma rays through a collimator to form a high - quality high - dose radiation field. the size of radiation filed can be varied and shaped according to tumor size for 3d radiotherapy. therefore, it can effectively increase radiation dose to tumor tissues and decease radiation dose to normal tissues
根據幾何聚焦原理,將30束鈷60伽瑪射線通過準直后經一個固定的軸線旋轉聚焦,形成品質優良的高劑量區分佈,經治療計劃系統的優化,可使高劑量區的劑量分佈,在三維方向上和腫瘤的形狀一致,從而實現三維適形放射治療。Before we actualize the radiation to the patient, we must plan the therapy and simulate the process of the treatment, calculate the distribution of the radiation doses to evaluate the treatment planning. due to the computer visualization technology, we got an accurate way, intuitionistic and efficient, to constitute the treatment planning
為了實現精確的放射治療,我們需要在實際進行放射治療之前,制定正確的放療計劃,並對射線的放療過程進行模擬,計算放射劑量的分佈情況,從而明確放療效果,確定放療計劃的優劣。分享友人
