Performance of myocardial perfusion imaging using multi-focus fan beam collimator with resolution recovery reconstruction in a comparison with conventional SPECT
Objective: IQSPECT is an advanced high-speed SPECT modality for performing myocardial perfusion imaging (MPI), which uses a multi-focus fan beam collimator with resolution recovery reconstruction. The aim of this study was to compare IQSPECT compared with conventional SPECT interms of performance based on standard clinical protocols. In addition, we examined the concordance between convention...

متن کاملLABORATORY INVESTIGATION SINGLE-PHOTON EMISSION TOMOGRAPHY Quantitation of size of relative myocardial perfusion defect by single-photon emission computed tomography
The purpose of this study was to validate a semiautomatic method for quantitating the size of relative myocardial perfusion defects from single-photon emission computed tomographic (SPECT) images. We compared the size of the image defect in vivo, expressed as percent of involved left ventricle, as determined by this method with the anatomic size of the defect in vitro in 19 dogs. To test the me...
متن کاملImage Optimization in Single Photon Emission Computed Tomography by Hardware Modifications with Monte Carlo Simulation
Introduction: In Single Photon Emission Computed Tomography (SPECT), the projection data used for image reconstruction are distorted by several factors, including attenuation and scattering of gamma rays, collimator structure, data acquisition method, organ motion, and washout of radiopharmaceuticals. All these make reconstruction of a quantitative SPECT image very difficult. Simulation of a SP...
