We demonstrate the use of highly parallel graphics processing units (GPUs) to accelerate the superposition/convolution (S/C) algorithm to interactive rates while reducing the number of approximations. S/C first transports the incident fluence to compute the total...
Our group has constructed the small animal radiation research platform (SARRP) for delivering focal, kilo-voltage radiation to targets in small animals under robotic control using cone-beam CT guidance. The present work was undertaken to support the SARRP's treatment...
Small animal research allows detailed study of biological processes, disease progression, and response to therapy, with the potential to provide a natural bridge to the clinical environment. The Small Animal Radiation Research Platform (SARRP) is a portable system for...
The American Association of Physicists in Medicine (AAPM) formed a Task Group under the Unconventional Brachytherapy Working Group of the Brachytherapy Subcommittee and the Radiation Safety Subcommittee of the Therapy Physics Committee (TPC). This Task Group, TG-152,...
Preclinical research using well characterized small animal models has provided tremendous benefits to medical research, enabling low cost, large scale trials with high statistical significance of observed effects. The goal of the Small Animal Radiation Research...
BACKGROUND: We explore the use of a clinical orthovoltage X-ray treatment unit as a small-animal radiation therapy system in a tumoral model of cervical cancer. METHOD: Nude mice were subcutaneously inoculated with 5 × 106 HeLa cells in both lower limbs. When tumor...
Accurate measurement and knowledge of dose delivered during superficial x-ray radiotherapy is required for patient dose assessment. Some tumours treated near the surface (within the first few centimetres) can have large posterior bone structures. This can cause...
BACKGROUND: The incidence of skin cancer has increased dramatically, with as many as 2.8 million skin cancers treated in 2005. In an era of decreasing reimbursement, insurer policy changes, and increasing pressure to deliver cost effective care, physicians should...
PURPOSE: To demonstrate the computed tomography, conformal irradiation, and treatment planning capabilities of a small animal radiation research platform (SARRP). METHODS AND MATERIALS: The SARRP uses a dual-focal spot, constant voltage X-ray source mounted on a...
