Journal ArticleDOI
A Method for Attenuation Correction in Radionuclide Computed Tomography
TL;DR: The method for attenuation correction in RCT is applied a simple, effective two-step procedure to the uncorrected image, and the filtered back-projection algorithm is used for its fast speed.
Journal ArticleDOI
Whole-body single-photon emission computed tomography using dual, large-field-of-view scintillation cameras
TL;DR: Phantoms and clinical data demonstrate that the SPECT system generates high quality section images while maintaining most of the flexibility of normal scintillation cameras, with the added advantage of dual heads.
Journal ArticleDOI
Attenuation Correction and Incomplete Projection in Single Photon Emission Computed Tomography
TL;DR: In this paper, an algorithm is developed to compensate for the effect of attenuation of?-rays within the body using a constant attenuation coefficient and a known body contour.
Journal ArticleDOI
Single Photon Emission Computed Tomography Using Multi-Slice Fan Beam Collimators
TL;DR: It is concluded that the fan-beam collimator system, when compared with conventional parallel-hole collimators, produces simultaneous improvements in SP/ECT system sensitivity and resolution, which results in improved visualization of small centrally located organs.
