Radiation dosimetric simulation models are required by radiation oncologists prior to the delivery of radiation dose to a cancer patient. A knowledge of Three Dimensional (3D) dose distribution treatment plan is highly desirable to deliver a lethal radiation dose to a tumor site while minimizing the hazardous effects on healthy and critical tissues. A 3D dose computation in Radiation Therapy Treatment Planning (RTTP) is heavily CPU intensive. In this dissertation parallel computer architectures based on Recruit-On-Demand (ROD) strategy have been studied that exploits the spatially distributed independent data in an irradiated volume. Utilizing Computed Tomographs (CT) scans information, three different architectures are studied. In the first architecture, information about radiation beams and CT slices is mapped on a parallel architecture. In the second study, a one dimensional parallel architecture based on ROD strategy has been done. In the final study a two dimensional ROD architecture has been studied to calculate dose in RTTP. The simulation results show that by using a particular algorithm and ROD strategy, 3D dose in RTTP can be computed in real time.Subjects--Topical Terms:
