A correlation study of 2D and 3D gamma passing rates for prostate IMRT plans
Purpose: To investigate the correlation between the two-dimensional gamma passing rate (2D％GP) and three-dimensional gamma passing rate (3D ％GP) in prostate IMRT quality assurance.Methods: Eleven prostate IMRT plans were randomly selected from the clinical database and were used to obtain dose distributions in the phantom and patient.Three types of delivery errors(MLC bank sag errors, central MLC errors and monitor unit errors) were intentionally introducedto modify the clinical plans through an in-house Matlab program.
