Lens dose is a concern during the treatment of facial lesions with anterior electron beams. Lead shielding is routinely employed to reduce lens dose and minimize late complications. The purpose of this work is twofold: 1) to measure dose pro-files under large-area lead shielding at the lens depth for clinical electron energies via film dosimetry; and 2) to assess the accuracy of the Pinnacle tr...
Total body irradiation (TBI) is a well-established component of several conditioning regimens required before bone marrow or hematopoietic stem cell transplantation. In this work, we validate the imparted dose in TBI technique using VMAT Médica Sur. We used an anthropomorphic phantom ATOM 702-D, CIRS (Norfolk, Virginia), add upper extremities homemade material and scanned it CT scanner GE 580RT...
Understanding the dose distribution of beta-emitting eye plaques respect to the location of tumor is of importance. In this study, the geometry of CCB, COB and CIB plaques (BEBIG manufacturer) for specific eye tumors were simulated and the effects of different coated radionuclides and plaque materials were investigated, by Geant4 simulation toolkit. For validation, a dosimetric investigation wa...
