Implementation of an Environment for Monte Carlo Simulation of Fully 3-D Positron Tomography on a High-Performance Parallel Platform

This paper describes the implementation of the Eidolon Monte Carlo program designed to simulate fully three-dimensional (3-D) cylindrical positron tomographs on a MIMD parallel architecture. The original code was written in Objective-C and developed under the NeXTSTEP development environment. Di€erent steps involved in porting the software on a parallel architecture based on PowerPC 604 process...

Determination of the Energy Windows for the Triple Energy Window Scatter Correction Method in Gadolinium-159 Single Photon Emission Computed Tomography Using Monte Carlo Simulation

Introduction: In radionuclide imaging, object scatter is one of the major factors leading to image quality degradation. Therefore, the correction of scattered photons might have a great impact on improving the image quality. Regarding this, the present study aimed to determine the main and sub-energy windows for triple energy window (TEW) scatter correction method usin...

An Efficient Approach to Switching Activity Estimation in Finite State Machines

This paper presents a methodology for determining the average power consumption of sequential CMOS circuits based on a ‘high-level’ FSM description. Starting from a exercised symbolic FSM description, a Monte Carlo simulation is used to estimate the average switching activity of all circuit components. Depending on user-supplied modelling parameters this simulation system can be used as a ‘circ...

Improvement of the performance and accuracy of PET Monte Carlo simulations

The many applications of Monte Carlo modelling in PET arouse to increase the accuracy and computational speed of Monte Carlo codes. The accuracy of Monte Carlo simulations strongly depends on cross-section libraries used for photon transport calculations. Furthermore, large amounts of CPU time are required to obtain meaningful simulated data. We present a comparison of different photon cross-se...
