isodose

基本解釋

Match specified isodose contours to the target volumes.
放射外科學的目的是消除腫瘤細胞同時保存正常的結構.;由于治療過程中會涉及物理限制和生物不確定性，一個治療方案就需要考慮到所有那些限制和不確定性。
Although 80% isodose line coverd CTV, the dose to the lens was 30% of the total dose by 20MeV electron irradiation.
2 0MeV電子線 80%25的等劑量曲線覆蓋靶區(qū) ,晶狀體劑量為 3 0%25。
A median dose of 20 Gy prescribed to the 80% isodose line was administered in a single fraction.
中位值為20戈瑞劑量（建議達80%25的等劑量線）以單成分方式給予患者。
Results The planning target volume was enclosed by 95%isodose line while the dose to the organ at risk were kept below TD5/5 significantly.
結果 95%25等劑量線包繞計劃靶區(qū)，危及器官的受量大大低于其耐受劑量(TD5/5)。
The technologies are emphasized, including image collection, preprocessing, edge detection and selection, calculating the dose of the point and drawing the isodose.
著重探討了系統(tǒng)的實現(xiàn)技術，包括模擬定位機下定位圖像的采集、預處理、邊緣識別與提取、任意點的劑量計算和等劑量曲線的繪制等。
