An image-guided study of setup reproducibility of post-mastectomy breast cancer patients treated with inverse-planned intensity-modulated radiation therapy (IMRT)

摘要

Purpose/Objective(s)To calculate planning target volume (PTV) margins for chest wall and regional nodal targets using daily orthogonal kV imaging, and to study residual setup error after kV alignment using volumetric cone-beam computed tomography (CBCT).
