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 accuracy of the reconstructed images obtained from a 180ÂSPECT acquisition is
directly related to the effects of resolution and attenuation inthe acquired projection data …

Background In cardiac imaging systems, an elliptic acquisition orbit about the patient can be
used to enhance resolution of single photon emission computed tomography (SPECT) …

In order to understand the angular dependence of reconstructed images, a" hot rod"
phantom was simulated with six rod sizes ranging from 12.7 mm to 4.8 mm, arranged in …

Misalignment between the electronic and mechanical axes of rotation will result in artifact
generation and image degradation during single photon emission computed tomography …

To investigate geometric distortion when 180 degrees or 360 degrees angular sampling
techniques are used in single photon emission computed tomography (SPECT), a study of …

Two articles in this issue [Coleman et al.(1) and Tamaki et al.(2)] are concerned with the pos
sibility of single-photon emission computed tomography (SPECT) of the myocardium with 11 …

Methods: Monte Carlo simulationsand real acquisitionof a" mTc cardiac phantom were
performed under comparable conditions. Simulated and acquired data were reconstructed …

DISCUSSION The influence of finite spatial resolution on object size cannot be ignored in
quantitative analysis by SPECT. We investigated the effect of spatial resolution on the …

Multiple pinholes are advantageous for maximizing the use of the available field of view
(FOV) of compact small animal single photon emission computed tomography (SPECT) …
