Epiqa TM is a program that allows to convert a dosimetric image acquired by an EPID into a dosemap and to compare the dosemap with a reference dose distribution. It is possible to utilize Epiqa for a verification of static as well as intensity modulated fields, including RapidArc ® fields. This text attempts to provide an overview of applied principles, describe the workflow, and discuss obtain...

Introduction Total body irradiations (TBI) for conditioning patients with leukemia prior to bone marrow transplantation (BMT) require time consuming verification of shielding block positions as well as dosimetric control. Short treatment times contribute to reproducibility and patient comfort and increase the accelerator capacity. To reduce setup time conventional port films were replaced by a ...

Background: To correct patient positioning errors (setup errors) during prostate cancer treatment using EPID and fiducial gold markers, to improve the accuracy of the dose delivery in these patients. Materials and Methods: Fifteen patients with localized prostate carcinoma after implantation of fiducial gold markers in their prostate gland underwent the five-field IMRT planning technique. The p...
