Attenuation is believed to be one of the major causes of false-positive cardiac single-photon
emission computed tomographic perfusion images. This article provides an introduction to …

Spherically symmetric volume elements with smooth tapering of the values near their
boundaries are alternatives to the more conventional voxels for the construction of volume …

A Bayesian method is presented for simultaneously segmenting and reconstructing
emission computed tomography (ECT) images and for incorporating high-resolution …

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

In emission tomography, the spread of regional tracer uptake to surrounding areas caused
by limited spatial resolution of the tomograph must be taken into account when quantitating …

Abstract Effects of different scatter compensation methods incorporated in fully 3D iterative
reconstruction are investigated. The methods are:(i) the inclusion of anideal scatter …

In single photon emission computed tomography (SPECT) with parallel hole collimation,
image reconstruction is usually performed as a set of bidimensional (2D) analytical or …

The accuracy of the system model in an iterative reconstruction algorithm greatly affects the
quality of reconstructed positron emission tomography (PET) images. For efficient …

AIM: Corrective image reconstruction methods which produce reconstructed images with
improved spatial resolution and decreased noise level became recently commercially …
