Design outcomes

Primary

MeasureTime frame
On the postoperative day1 and day3, (MRI1) (MRI2) were performed. These MRIbased plans were reconstructed to measure the dosimetric parameters such as V90, V150 and max doses against the skin and the chest wall. These dosimetric factors were the primary evaluation items in this study
