What is Daily Portal Imaging of Implanted Fiducial Markers During IMRT Treatment of Prostate Cancer: a Community-Based Centers Experience about?
Purpose/Objective: IGRT technology can be used to correct for prostate motion which, based on data from multiple studies, can be as much as 2 cm. Both deformation and dislocation of the prostate can occur, with target day-to-day dislocation having the dominant effect. The same amount of movement may create different degradation of planning target volume (PTV) coverage for different movement directions when patients are treated with IMRT. This study quantifies dosimetric deviations for prostate movements in individual directions. Materials/Methods: A total of 10 prostate cases with the GTV ranging from 15 cc to 100 cc were selected for this study. IMRT plans that have 95% of the PTV (1 cm uniform margin from GTV) volume covered by the prescription dose of 75.6 Gy were generated. The dose objectives for the rectum and bladder were that less than 20% of each volume would receive more than 65 Gy. Eight gantry directions were used. Two IMRT plans using collimator angles 0o and 90o were generated to study the effect of different intensity distribution. To simulate prostate shifts, virtual systematic movements of the targets of 3 mm, 5 mm and 10 mm were introduced in the anterior (ANT), p
