Dosimetric Evaluation of Breathing Impact on PTV and Adjacent Organ At Risk in Breast Cancer Radiotherapy

Patients with breast cancer scheduled for radiotherapy will be selected based on specific inclusion and exclusion criteria. Patients will undergo imaging studies, such as computed tomography (CT) scans, to define the target volumes and OARs. The study aims to provide insights into the dosimetric impact of breathing motion on PTV and OARs in breast cancer radiotherapy, which can inform strategies to improve treatment planning and delivery.
