本研究的目的是量化危险器官的剂量差异，并比较俯卧位和仰卧位乳房下垂患者的PTV覆盖率和剂量均匀性。10例患者采用俯卧位和仰卧位ct治疗方案。收集了有关剂量均匀性和危及器官剂量的数据。俯卧位的剂量均匀性更好，危险器官的剂量更低，但在目前的技术下，这是以降低PTV覆盖率为代价的。2006爱思唯尔爱尔兰有限公司版权所有。
The purpose of this study was to quantify the differences in doses in the organs at risk and to compare the PTV coverage and dose homogeneity of patients with pendulous breasts between prone and supine position. In 10 patients a CT-based treatment plan was made in prone and supine position. Data about dose homogeneity and doses to organs at risk were collected. Dose homogeneity turned out to be better in prone position and doses in organs at risk were lower, but with the current technique, this occurred at the cost of a reduced PTV coverage.
