CONSTRUCTION OF SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY (SPECT) CONFIGURATION FOR SERVING TESTING FLOW MODELS

Abstract

Both Radiotracer technique to collect residence time distribution and Computational Fluid Dynamics to simulate fluid flow for reaction systems requires complex calculation, sometimes it is difficult to interpret results. Single Photon Emission Computed Tomography (SPECT), which is a nuclear imaging scan that integrates computed tomography (CT) and a radioactive tracer, is a useful method for visually verifying the results of experiments in studying radiotracer behaviors in the reaction systems. Using multiple radioactive probes at a cross - section of the system at which the cross-sectional image of the tracer distribution can be reproduced from the measurement data with an appropriate image-rendering algorithm. The SPECT configuration in this report was studied and selected as the hexagonal configuration, the resolution reached 30mm, the time for a slice of 20 seconds. The SPECT configuration is used by the application to investigate the distribution of the tracer in the liquid medium.
