SPECT has traditionally been regarded as nonquantitative. Advances in multimodality γ-
cameras (SPECT/CT), algorithms for image reconstruction, and sophisticated compensation …

Reliable attenuation correction methods for quantitative emission CT (ECT) require accurate
delineation of the body contour and often necessitate knowledge of internal anatomic …

Image registration is the process of systematically placing separate images in a common
frame of reference so that the information they contain can be optimally integrated or …

The introduction of combined modality single photon emission computed tomography
(SPECT)/CT cameras has revived interest in quantitative SPECT. Schemes to mitigate the …

Attenuation correction in single-photon (SPET) and positron emission (PET) tomography is
now accepted as a vital component for the production of artefact-free, quantitative data. The …

Radionuclide imaging of cardiac function represents a number of well-validated techniques
for accurate determination of right (RV) and left ventricular (LV) ejection fraction (EF) and LV …

Single-photon emission computed tomography/computed tomography (SPECT/CT) has
emerged during the past decade as a means of correlating anatomical information from CT …

Single photon emission computed tomography (SPECT) has a long history of development
since its initial demonstration by Kuhl and Edwards in 1963. Although clinical utility has …

Many different types of radiation have been exploited to provide images of the structure and
function of tissues inside a living subject. Each imaging modality is characterized by differing …

Simultaneous correction of nonuniform attenuation and detector response was implemented
in single-photon-emission computed tomography (SPECT) image reconstruction. A ray …
