Single photon emission computed tomography (SPECT) is an important imaging modality for
various applications in nuclear medicine. The use of multi-pinhole (MPH) collimators can …

This article presents and validates a newly developed GATE model of the Siemens Inveon
trimodal imaging platform. Fully incorporating the positron emission tomography (PET) …

Purpose: A dedicated cardiac hybrid single photon emission computed tomography
(SPECT)/CT scanner that uses cadmium zinc telluride detectors and multiple pinhole …

SPECT is primarily used in the clinic for cardiac myocardial perfusion imaging. However, for
SPECT, sensitivity is impaired due to the need for collimation. System resolution FWHM is …

In this paper, an acronym for stereo vision calibration-point spread function (SVC-PSF), is
designed to accurately represent image degradation in large-depth-of-field (LDOF). The …

SPECT imaging of the dopamine transporter (DAT) is used for diagnosis and monitoring
progression of Parkinson's disease (PD), and differentiation of PD from other neurological …

Accurate gamma photon transport simulations of emission tomography systems are
important to optimise system geometries and for iterative image reconstruction. Monte Carlo …

Purpose: To assess the performance of two approaches to the system response matrix
(SRM) calculation in pinhole single photon emission computed tomography (SPECT) …

Purpose Single‐photon emission computed tomography (SPECT) is a noninvasive imaging
modality, used in myocardial perfusion imaging. The challenges facing the majority of …

The use of multi-pinhole collimation has enabled ultra-high-resolution imaging of SPECT
and PET tracers in small animals. Key for obtaining high-quality images is the use of …
