Four sets of images were prepared (Table 1). Because statistical power in ROC studies was
maximized when approximately half of the images were normal (7), half of the images in …

There has been considerable debate about the desirability of attenuation correction in whole-
body PET oncology imaging. The advantages of attenuation correction are quantitative …

This paper describes a new approach to determine individual scatter kernels and to use
them for scatter correction by integral transformation of the projections. Methods: Individual …

MATERIALS AND METHODS An ROC study with a matched-pair design was used to
facilitate accurate, meaningful comparisons between modalities. Issues in the proper …

The aim of this work was to develop a rigorous evaluation methodology to assess
performance of different acquisition and processing methods for variable patient sizes in the …

PET image quality measurements of lesion detectability frequently use a small, radioactive
sphere in a larger phantom. The typical analysis of a small single sphere in background has …

Iterative reconstruction has become the standard for routine clinical PET imaging. However,
iterative reconstruction is computationally expensive, especially for time-of-flight (TOF) data …

Abstract In Positron Emission Tomography, there are several causes of quantitative
inaccuracy, such as partial volume or spillover effects. The impact of these effects is greater …

RC (@ x) would be equal to unity or zero, depending upon whether the detector were
positioned over the object. In PET imaging, RC (@ x) is dependent upon the total system …

In whole‐body positron emission tomography (PET) imaging, the detection of small uptake
foci (ie, around two or three times the tomograph's spatial resolution) is a critical issue …
