AIM The aim of this work was to develop multiple-source models for electron beams of the NEPTUN 10PC medical linear accelerator using the BEAMDP computer code. BACKGROUND One of the most accurate techniques of radiotherapy dose calculation is the Monte Carlo (MC) simulation of radiation transport, which requires detailed information of the beam in the form of a phase-space file. The computing...
In this paper we show an O(n log n) time algorithm for finding a maximum flow in a planar graph with multiple sources and multiple sinks. This is the fastest algorithm whose running time depends only on the number of vertices in the graph. For general (nonplanar) graphs the multiple-source multiple-sink version of the maximum flow problem is as difficult as the standard single-source single-sin...
In this study, cardiac current source localization was simulated using the spatial filter method. We estimated sources data from two measurement surfaces, i.e., front and back of subject, to reduce large extension in depth direction. Three methods for creating filters were developed exact low-resolution brain electromagnetic tomography method based on different creation procedures. The first is...
multiple sclerosis (ms) is a chronic disease of central nervous system. the multiple sclerosis information system (msis), such as other information system (is), depends on identification, collection and processing of data for producing useful information. lack of the integrated is for collecting standard data causes undesirable effects on exchanging, comparing, and managing. the aim of this stu...
