Monte Carlo (MC) simulation is an established tool to calculate photon transport through
tissue in Emission Computed Tomography (ECT). Since the first appearance of MC a large …

The task of single photon emission CT (SPECT) is to visualize the physiological function of
various organs with the help of radiopharmaceuticals. But the projection data used for image …

A circular 180° acquisition orbit is considered standard for cardiac SPECT imaging.
Theoretically, a 360° acquisition orbit is preferred because of more complete Fourier …

The acquisition and processing of the Jaszczak phantom is a recommended test by the
American College of Radiology for evaluation of gamma camera system performance. To …

201Tl-Chloride (201Tl) is a myocardial perfusion SPECT agent with excellent biochemical
properties commonly used for assessing tissue viability. However, cardiac 201Tl SPECT …

We aimed to compare the measurement and simulation data of bone scintigraphy of a chest
phantom using a Monte Carlo simulation to verify the accuracy of the simulated data. The …

Background The optimal projection data acquisition strategy for myocardial perfusion (MP)
single photon emission computed tomography (SPECT) remains controversial. Methods We …

Nonuniform attenuation, Compton scatter, and limited, spatially varying resolution degrade
both the qualitative and quantitative nature of myocardial perfusion SPECT. Physicians must …

Objectives In myocardial perfusion imaging, the type of orbit that provides the best image
quality is still the subject of debate. This study correlates the effects of angular rotation (180 …

The aim of this study was to determine the reproducibility of measurements of the size and
severity of myocardial defects from" mTc sestamibi cardiac phantom studies performed on …
