A sparsity-exploiting algorithm intended for few-view single photon emission computed
tomography (SPECT) reconstruction is proposed and characterized. The algorithm models …

Dedicated cardiac single photon emission computed tomography (SPECT) systems have
the advantage of high speed and sensitivity at no loss, or even a gain, in resolution. The …

Existing single-photon emission computed tomography (SPECT) reconstruction methods are
mostly based on discrete models that may be viewed as piecewise constant approximations …

A mathematical framework for quantitative SPECT (single photon emission computed
tomography) reconstruction of the heart is presented. An efficient simultaneous …

Quantitative accuracy of single photon emission computed tomography (SPECT) images is
highly dependent on the photon scatter model used for image reconstruction. Monte Carlo …

Because the effects of physical factors such as photon attenuation and spatial resolution are
distance-dependent in single-photon emission computed tomography (SPECT), it is …

We compare two different implementations of a 3D SPECT system model for iterative
reconstruction, both of which compensate for non-uniform photon attenuation and depth …

Single-photon emission computed tomography (SPECT) is a method of choice for imaging
spatial distributions of radioisotopes. Applications of this method are found in medicine …

Purpose: The authors have recently developed a preconditioned alternating projection
algorithm (PAPA) with total variation (TV) regularizer for solving the penalized‐likelihood …

The goal of this paper is to investigate different reconstruction methods for solving the limited
angle problem in reconstructing the projection data from a stationary multi-pinhole system …
