研究目的: |
1.主要目的: •量化腹部加压对保乳术后患者乳腺呼吸运动幅度(三维方向)的抑制效果。 •评估腹部加压对放疗计划中OARs(重点关注:同侧肺V5、V20、Dmean,对侧肺V5;冠状动脉V15,V40;心脏V5,Dmean)的剂量学参数的影响。 2.次要目的: •探索乳腺运动幅度与OARs剂量参数的相关性。 •探索腹部加压后的放射性肺炎的发生率。 |

|
Objectives of Study: |
1. Main purpose: Quantify the inhibitory effect of abdominal compression on the amplitude (three-dimensional direction) of breast respiratory movement in patients after breast-conserving surgery. To evaluate the impact of abdominal compression on the dosimetric parameters of OARs (with a focus on: ipsilateral lung V5, V20, Dmean, contralateral lung V5; coronary artery V15, V40; heart V5, Dmean) in the radiotherapy plan. 2. Secondary objectives: Explore the correlation between the amplitude of breast movement and OARs dose parameters. Explore the incidence of radiation pneumonitis after abdominal compression. |
