In this work, we studied the possibility of merging proton therapy with grid therapy. We hypothesized that patients with larger targets containing solid tumor growth could benefit from being treated with this method, proton grid therapy. We performed treatment planning for 2 patients with abdominal cancer with the suggested proton grid therapy technique. The proton beam arrays were cross-fired ...

Grid radiation therapy with megavoltage x-ray beam has been proven to be an effective technique for management of large, bulky malignant tumors. The clinical advantage of GRID therapy, combined with conventional radiation therapy, has been demonstrated using a prototype GRID block [Mohiuddin, Curtis, Grizos, and Komarnicky, Cancer 66, 114-118 (1990)]. Recently, a new GRID block design with impr...

This document was developed to help occupa· tional therapists apply Uniform TerminologySecond Edition to practice. A grid format (Dunn, 1988) allows a therapist to systematically identify an individual's deficit and strength areas and to select appropriate activities to address these areas in occupational therapy intervention. On the grid (see Appendix A), the horizontal axis is composed of the...

PurposeTo describe a novel and practical volumetric modulated arc therapy (VMAT) planning approach for grid therapy.Methods MaterialsDose is prescribed to 1.5-cm diameter spherical contours placed throughout the gross tumor volume (GTV). Placement of spheres variable, but they must maintain at least 3-cm (center center) separation, edge any sphere be 1 cm from organ risk (OAR). Three concentric...

This paper introduces the Repertory Grid Technique (RGT), developed in personal construct psychology, for Technology Enhanced Formative Assessment (TEFA). Repertory Grid is a method for eliciting personal constructs of learners about elements belonging to the topic of study. The method of Repertory Grid is presented first followed by brief descriptions of two classroom studies and two eye-track...

By using cloud computing it is possible to provide on- demand resources for epidemic analysis using computer intensive applications like SaTScan. Using 15 virtual machines (VM) on the Nimbus cloud we were able to reduce the total execution time for the same ensemble run from 8896 seconds in a single machine to 842 seconds in the cloud. Using the caBIG tools and our iterative software developmen...
