Webtool kit. This tool kit is based on the TASMIP [4] algorithm developed by Boone and Seibert. The 3D volumes were used in a MC simulation to generate the scatter signal for the image. A MC simulation of x-ray transport in a graphic processor unit (GPU) with Compute Unified Device Architecture (CUDA) was used [5]. This accelerated Monte Carlo ... WebThe best results for angular distribution was obtained when the EGS-based algorithm was used. It can be noted that patient doses determined by using Kahn or “classic” procedures are in good agreement with data from literature when similar computing methods are used. From our data, for patient dose calculations, the EGS procedure is recommended. marine monument washington dc
