PURPOSE After apparently successful excision of breast cancer, risk of local recurrence remains high mainly in the area surrounding the original tumor, indicating that wound healing processes may be implicated. The proportional reduction of this risk by radiotherapy does not depend on the extent of surgery, suggesting that radiotherapy, in addition to(More)
The dosimetry of the fields usually employed in radiosurgery requires the use of small detectors to measure Total Scatter Factor (Sc,p), Tissue Maximum Ratio (TMR), Percentage Depth Dose (PDD), and Off Axis Ratio (OAR). In this paper new dosimeters are investigated: a new type of radiochromic film, a micro parallel-plate chamber (filled with both air and(More)
10611 Background: Most recurrences after breast conserving surgery for cancer occur in the tissues around the original tumour. Wound-fluid has been shown to induce proliferation of breast carcinoma cells. We investigated whether intraoperative radiotherapy (IORT) using the targeted intraoperative radiotherapy (Targit) technique changes the effect of(More)
The purpose of this work is to compare the photon dose calculation of a commercially available three-dimensional (3D) treatment planning system based on the collapsed cone convolution technique against BEAM, a Monte Carlo code that allows detailed simulation of a radiotherapy accelerator. The first part of the work is devoted to the commissioning of BEAM(More)
PURPOSE Virtual Wedges were introduced in Siemens LINACs to improve the treatment workflow. The aim of the present work is the validation of dose calculation by MasterPlan-Oncentra treatment planning system for virtual wedged beams. METHODS The Oncor Siemens accelerator installed in the authors' department produces 6 and 15 MV photon beams. At first, the(More)
