TCT data were acquired separately or simultaneously. Results: SPECT quantification and
image quality were improved by perform ing this correction. The activity concentration  …

Attenuation Compensation in 99mTcSPECT Brain Imaging: A Comparison of the Use of
Attenuation Maps Derived from Transmission Vers Page 1 Attenuation Compensation in …

Objective (s): The aim of this study was to evaluate the influences of reconstruction and
attenuation correction on the differences in the radioactivity distributions in 123 I brain …

Correction of scatter and attenuation is essential for quantitative SPECT. In this work, we
evaluated the accuracy gained from a method of transmission-dependent convolution …

We present a correction technique that uses the effective bone and tissue attenuation
coefficients to compensate 99mTc-HMPAO brain SPECT projections for attenuation …

A method for attenuation and scatter correction of brain single photon emission computed
tomography (SPECT) is described where computed tomography (CT) images of the brain …

Objective: Scatter correction is an important factor in quantitative SPECT. In this study, we
evaluated 2 methods of scatter correction for brain SPECT. The first is based on thresholding …

To make it possible to share a normal database in single photon emission computed
tomography (SPECT) studies, we developed a new method for converting a SPECT image …

The aim of this study was to obtain quantitative iodine-123 brain single-photon emission
