OBJECTIVE Due to the fundamental differences in treatment delivery, linear-accelerator-based radiosurgery can be complementary to Gamma Knife (GK) for intracranial lesions. We reviewed the effect of adding GK to an existing linear accelerator (Linac)-based radiosurgery practice and analyzed case selections for the two modalities. PATIENTS AND METHODS UC(More)
Three dimensional (3D) scanning and printing technology is utilized to create phantom models of mice in order to assess the accuracy of ionizing radiation dosing from a clinical, human-based linear accelerator. Phantoms are designed to simulate a range of research questions, including irradiation of lung tumors and primary subcutaneous or orthotopic tumors(More)
OBJECT Stereotactic radiosurgery is beneficial for patients with a limited number of small brain metastases. Increased numbers of brain metastases, not infrequently at unreachable locations, are identified using thin-section magnetic resonance (MR) imaging on the day of Gamma Knife surgery (GKS). To improve patient selection and design better treatment(More)
This report presents a rare case of multiple, widely spaced arteriovenous malformations in a single patient treated with linear accelerator-based radiosurgery. The choices associated with the requisite imaging and planning are presented. In light of the anatomic topography, linear accelerator-based radiosurgery was chosen over gamma knife treatment, with CT(More)
