Improved Algorithms in Monte Carlo Device Simulation
نویسندگان
چکیده
Algorithms are presented which advance the state of the art in Monte Carlo device simulation in two ways. Firstly, a method of free-flight time calculation using a new self-scattering algorithm is described. A piecewise linear total scattering rate allows for an efficient reduction of self-scattering events. Secondly, a unique Monte Carlo-Poisson coupling scheme is adopted, which converges faster than presently known schemes do. It is based on so-called Monte Carlo-Drift Diffusion coupling, a method which can be rigorously justified within the semiclassical Boltzmann transport theory.

متن کاملInvestigation of Collimator Influential Parameter on SPECT Image Quality: a Monte Carlo Study
Background: Obtaining high quality images in Single Photon Emission Tomography (SPECT) device  is the most important goal in nuclear medicine. Because if image quality is low, the possibility of making a mistake in diagnosing and treating the patient will rise. Studying effective factors in spatial resolution of imaging systems is thus deemed to be vital. One of the most important factors in S...
