【摘要】：文章通過比較具體臨床算例下Galvin、Siochi、Luan 3種典型精確放療多葉光柵射野分割算法輸出結(jié)果,研究不同算法對多葉光柵葉片序列優(yōu)化效果。通過采用3種葉片序列算法比較總子野個(gè)數(shù)和總機(jī)器跳數(shù)結(jié)果來改進(jìn)臨床多葉光柵葉片序列輸出的方法,可以根據(jù)不同臨床需求獲得放射治療時(shí)間較短或光子利用率較高的子野分割效果,是一種有效的葉片序列優(yōu)化策略,在治療計(jì)劃系統(tǒng)中有廣闊的應(yīng)用前景。
[Abstract]:In this paper, we compare the output results of three typical accurate radiotherapy-induced multileaf grating field segmentation algorithms for Galvinn Siochion Luan in a specific clinical example. The effects of different algorithms on the leaf sequence optimization of multileaf grating were studied. The method of clinical multileaf grating leaf sequence output was improved by comparing the total number of subfields and the total machine hops with three leaf sequence algorithms. The sub-field segmentation effect with shorter radiotherapy time or higher photon utilization rate can be obtained according to different clinical needs. It is an effective leaf sequence optimization strategy and has a broad application prospect in the treatment planning system.
