Dosimetry and planning audit of IMRT prostate treatment in the Czech Republic with a pelvic phantom
Popis výsledku v původním jazyce
In 2013, the national end-to-end audit of IMRT prostate treatment with a pelvic phantom has been carried out in the Czech Republic. All departments where IMRT is used for prostate treatment participated. Phantom with clearly defined structures that werethe same for all departments has been used. The determination of absorbed doses with ionization chambers placed in the PTV and in the rectum and the comparison to the planned doses was performed. Planar dose distribution was verified with gafchromic film. Constraints used for planning, volumes calculation, and DVHs were analyzed. Homogeneity index and gEUD were calculated for PTV. Likewise, gEUD and NTCP were calculated for rectum and bladder. Ratio of gEUD to prescribed dose has been calculated. Dose-volume relationships have been evaluated considering QUANTEC. The influence of uncertainty in parameter a on the difference of rectum gEUD across departments has been estimated. CT numbers to RED conversion curves in the planning systems w
