Multimodal fusion in neuroimaging combines data from multiple imaging modalities to
overcome the fundamental limitations of individual modalities. Neuroimaging fusion can …

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

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 …

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

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

Detection of scattered gamma quanta degrades image contrast and quantitative accuracy of
single-photon emission computed tomography (SPECT) imaging. This paper reviews …

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

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 …

In nuclear medicine, clinical assessment and diagnosis are generally based on qualitative
assessment of the distribution pattern of radiotracers used. In addition, emission tomography …

Abstract 3D acquisition and reconstruction in positron emission tomography (PET) produce
data with improved signal-to-noise ratios compared with conventional 2D slice-oriented …
