Prostate bed motion during intensity-modulated radiotherapy
Webb22 jan. 2024 · Linda et al. observed prostate motion during treatment using pretreatment and post-treatment CBCTs and reported that the average absolute value of prostate displacement was 1.5 mm in the AP... WebbProstate bed motion was calculated for the upper and lower segments by measuring the position of surgical clips located close to midline relative to bony anatomy in the axial (translational) and sagittal (tilt) planes. The frequency of potential geographic misses was calculated for either 1 cm or 0.5 cm posterior planning target volume margins. Webbmotion of the prostate bed clinical target volume (PB-CTV) based on consensus Radiation Therapy Oncology Group (RTOG) definitions (instead of surgical clips/fiducials) was studied. It was assessed whether PB motion in the superior portion of PB-CTV (SUP-CTV) differed from the inferior PB-CTV (INF-CTV). Patientsandmethods EightpT2-3bN0 ... gummosis canker
