Four-dimensional (4D) CT images for charged particle lung therapy were acquired using a 256 multislice CT without couch movement. The thickness of the posterior right chest wall changed with respiration with a water equivalent path length (WEL) of more than 5 mm over the mid-exhalation phase but the thickness of the left chest wall did not vary.
采用 256 层多排 CT 扫描仪进行不带床运动的带电粒子肺部治疗四维(4D)CT 图像采集。在呼气中期,右后胸壁的厚度随呼吸而变化,水等效路径长度(WEL)超过 5 毫米,但左胸壁的厚度没有变化。
