SPECT is a rapidly changing field, and the past several years have produced new
developments in both hardware technology and image-processing algorithms. At the …

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

Functional nuclear medicine imaging with single-photon emission CT (SPECT) in
combination with anatomical CT has been commercially available since the beginning of …

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

With brain-dedicated multi-detector systems employing pinhole apertures the usage of
detectors facing the top of the patient's head (ie quasi-vertex (QV) views) can provide the …

Although scatter correction improves SPECT image contrast and thus image quality, the
effects of quantitation accuracy under various conditions remain unclear. The present study …

The objective of this work was to evaluate the lesion detection performance of four fully-3D
positron emission tomography (PET) reconstruction schemes using experimentally acquired …

In this paper we propose a comprehensive energy-based scatter correction approach for
positron emission tomography (PET). We take advantage of the marked difference between …

Purpose Correction for photon attenuation and scatter improves image quality with
conventional NaI-based gamma cameras but evaluation of these corrections for novel solid …

The basic principles of scintigraphy are reviewed and extended to 3D imaging. Single-
