Abstract Real-time monitoring of clinical carbon beams from a synchrotron accelerator was accomplished by using aluminum-enriched phosphate glass with silver activator. Build-up effects are often observed in commercially available silver-containing that strongly limit the use real-time dosimetry particle therapy fields. In this study, we modified composition adding an additional 0.2 mol% alumin...
The paper is devoted to review of development and application of EPR dosimetry with teeth in Ukraine. It deals with specific features of the EPR dosimetry protocol, which was developed and is practically used in SCRM for retrospective dosimetry of clean-up workers (liquidators). Extensive methodological research was conducted in SCRM in order to develop an original version of EPR dosimetric pro...
Intra-operative guidance in Transrectal Ultrasound (TRUS) guided prostate brachytherapy requires localization of inserted radioactive seeds relative to the prostate. Seeds were reconstructed using a typical C-arm, and exported to a commercial brachytherapy system for dosimetry analysis. Technical obstacles for 3D reconstruction on a non-isocentric C-arm included pose-dependent C-arm calibration...
OBJECTIVE Passive scattering proton beam (PSPB) radiotherapy for accelerated partial-breast irradiation (APBI) provides superior dosimetry for APBI three-dimensional conformal photon radiotherapy (3DCRT). Here we examine the potential incremental benefit of intensity-modulated proton radiotherapy (IMPT) for APBI and compare its dosimetry with PSPB and 3DCRT. METHODS Two theoretical IMPT plans...
Radiation therapy (RT) is a common treatment option for a wide variety of cancer types. Despite significant improvements in this technique over the past years, software tools for research in RT are limited to either expensive, closed, proprietary applications or heterogeneous sets of open-source software packages with limited scope, reliability, and user support. Our SlicerRT toolkit aspires to...
BACKGROUND Features of the tumor microenvironment influence the efficacy of cancer nanotherapeutics. The ability to directly radiolabel nanotherapeutics offers a valuable translational tool to obtain biodistribution and tumor deposition data, testing the hypothesis that the extent of delivery predicts therapeutic outcome. In support of a first in-human clinical trial with (64)Cu-labeled HER2-ta...
Abstract Introduction: This is the second of two papers giving an overview use Monte-Carlo techniques for radiotherapy applications. Methods: The first paper gave introduction and introduced some codes that are available to user wishing model different aspects treatment. It also aims serve as a useful companion curated collection on have been published in this journal. Results Conclusions: focu...
Medical dosimetry education occupies a specialized branch of allied health higher education. Noted international shortages of health care workers, reduced university funding, limitations on faculty staffing, trends in learner attrition, and increased enrollment of nontraditional students force medical dosimetry educational leadership to reevaluate current admission practices. Program officials ...
