PURPOSE The aim of this study was to compare magnetic resonance imaging (MRI) with computed tomography (CT) for liver cancer tumor definition for high-precision radiotherapy planning. METHODS AND MATERIALS Diagnostic quality MRI scans and triphasic CT scans, with the liver immobilized in exhale, were obtained at the time of radiation planning for 26(More)
PURPOSE A new ambulatory consultative clinic with integrated assessments by palliative care, radiation oncology, and allied health professionals was introduced to (1) assess patients with brain metastases at a regional comprehensive cancer center and (2) inform and guide patients on management strategies, including palliative radiotherapy, symptom control,(More)
PURPOSE To quantify the effect of contouring variation on stereotactic radiosurgery plan quality metrics for brain metastases. METHODS AND MATERIALS Fourteen metastases, each contoured by 8 physicians, formed the basis of this study. A template-based dynamic conformal 5-arc dose distribution was developed for each of the 112 contours, and each dose(More)
We construct a reactive lattice-gas cellular automaton (LGCA) for reaction±di€usion systems and provide extensive discussion of its software coding aspects. The software coding aspects provide rationale for some choices in the construction of LGCA which has been inspired by molecular dynamics. Portability of the C language source code, of the data(More)
PURPOSE To audit outcomes after introducing frameless stereotactic radiosurgery (SRS) for brain metastases, including co-interventions: neurosurgery, systemic therapy, and whole brain radiotherapy (WBRT). We report median overall survival (MS), local failure, and distant brain failure. We hypothesized patients treated with SRS would have clinically(More)
