AI Article Synopsis
- - The study focuses on improving the contouring process in adaptive radiotherapy (ART) by creating patient-specific contouring regions of interest (CRoIs) for better dose evaluation.
- - An empirical equation was developed to calculate the radius of these CRoIs, which were tested on 60 patients resulting in 301 unique treatment plans.
- - Findings showed that 94% of treatment plans successfully included the high dose fall-off within the CRoIs, leading to an estimated time-saving of 2.9 minutes per case, thus enhancing the efficiency of ART.
Article Abstract
Contouring during adaptive radiotherapy (ART) can be a time-consuming process. This study describes the generation of patient specific contouring regions of interest (CRoI) for evaluating the high dose fall-off in stereotactic abdominal ART. An empirical equation was derived to determine the radius of a cylindrical patient specific CRoIs. These CRoIs were applied to 60 patients and their adaptive fractions (301 unique treatment plans). Out of the 301 unique treatment plans, 284 (94%) treatment plans contained the high dose fall-off within the CRoI. There was an expected predicted average timesaving of 2.9-min-per case. Patient specific CRoIs improves the efficiency of ART.
