Comparison of six-degree-of-freedom registration errors across different anatomical registration regions in head and neck radiotherapy under identical CBCT conditions

Abstract Objective Cone-beam computed tomography (CBCT) has been widely adopted for patient setup evaluation and error correction in head and neck radiotherapy. Although different anatomical registration regions are routinely used in clinical practice, the characteristics of six-degree-of-freedom (6...
