Breast cancer remains the most common cancer in women and one of the leading causes of cancer-related death [The fundamentally effective approach to decrease the incidence of RP is to limit the lung radiation dose. Several parameters have been reported to be involved in the process of RP, including clinical factors and dosimetric factors [We hypothesized that patient-specific body geometry reflects the lung irradiation dose. Thus, our study attempts to construct an organ feature to reflect specific geometry using body markers. However, labeling markers manually is time-consuming. In recent years, deep learning (DL) has shown excellent performance in medical image segmentation, recognition, and classification [
