In positron emission tomography (PET) imaging, statistical iterative reconstruction (IR) techniques appear particularly promising since they can provide accurate system model. The model matrix which describes the relationship between image space and projection is important to quality. It contains some factors such as geometrical component blurring component. usually described by point spread function (PSF). A PSF derived from single photon incidence response studied. And then an IR method...
The Eplus-260 primate PET is an animal imaging system developed by the Institute of High Energy Physics, Chinese Academy Sciences, which designed to image non-human primates, especially brain large primates. consists 48 block detectors arranged in two 24-sided rings with a ring diameter 263 mm and axial extent 64 mm. Each detector composed 16 × cerium-doped lutetium-yttrium orthosilicate crystal array pixel size 1.9 10 mm3. This article presents performance evaluation scanner according...
Abstract Background Long‐axis positron emission tomography (PET) has emerged as one of the recent research directions in PET due to its ability significantly enhance sensitivity and counting performance for low‐dose imaging, rapid whole‐body dynamic imaging. Purpose The system presented this study is a long‐axis animal based on lutetium–yttrium orthosilicate silicon photomultiplier, designed imaging rats. It features diameter 143 mm an axial length 213.3 mm. This evaluated accordance with...
Positional single photon incidence response (P-SPIR) theory is researched in this paper to generate more accurate PSF-contained system matrix simply and quickly.The method has been proved highly effective improve the spatial resolution by applying Eplus-260 primate PET designed Institute of High Energy Physics Chinese Academy Sciences(IHEP).Simultaneously, meet clinical needs, GPU acceleration put use.Basically, P-SPIR takes both angle position crystal subdivision instead only into...
The Positron Emission Mammography imaging system (PEMi) provides a novel nuclear diagnosis method dedicated for breast imaging. With better resolution than whole body PET, PEMi can detect millimeter-sized tumors. To address the requirement of semi-quantitative analysis with radiotracer concentration map breast, new attenuation correction based on three-dimensional seeded region growing image segmentation (3DSRG-AC) has been developed. gives 3D connected as result instead slices. continuity...
