We present the comparative study of the analytical forward model and the statistical simulation of the Compton single scatter in the positron emission tomography. The formula of the forward model has been obtained using the single scatter simulation

Total-body PET image reconstruction follows a similar procedure to the image reconstruction process for standard whole-body PET scanners. One unique aspect of total-body imaging is simultaneous coverage of the entire human body, which makes it conven

Due to limited counts in voxel-wise time activity curves, the indirect methods that generate kinetic parametric image from dynamic PET reconstructions often have poor image quality. The TOF PET data can be naturally and efficiently stored in histoima

Effects of TOF Resolution Models on Edge Artifacts in PET Reconstruction from Limited Angle Data

Autor: Paul Gravel, Yusheng Li, Samuel Matej

Publikováno v: 2019 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC).

Limited angle data, such as data obtained from a dual panel Breast-PET system, result in substantial image blur in the directions coinciding with the missing cone of the image spectrum. On systems with time-of-flight (TOF) capabilities, this blur is
