An iterative Bayesian reconstruction algorithm for limited view angle tomography, or
ectomography, based on the three-dimensional total variation (TV) norm has been …

Purpose: A rotating multi‐segment slant‐hole (RMSSH) collimator is able to provide much
higher (times for four‐segment collimator with 30° slant angle) sensitivity than a parallel …

This dissertation presents a detailed investigation of the use of rotating slant-hole (RSH)
collimators in single-photon emission-computed tomography (SPECT). We propose RSH …

Medical imaging is today an important clinical tool in the diagnosis of many diseases and in
research. Medical imaging can be divided into two categories; anatomical and functional …

Ectomography is a limited view angle method, which has been implemented by rotating a
slant hole collimator in front of a stationary gamma camera detector. The system is mobile …

Scintigraphic tomography (SPECT) with a gamma camera is an established tool for the
diagnosis of disturbances in perfusion of the myocardium. The technique has been shown to …

The aim of this study was to investigate the feasibility of performing cerebral blood flow
(CBF) scintigraphy using the 3D method of Ectomography. Ectomography is a limited view …

Ectomography is a limited view angle method, which involves rotating a slant hole collimator
in front of a stationary gamma camera detector. It has been implemented on a mobile system …

SPECT using a rotating multi-segment slant-hole (RMSSH) collimator provides a superior
alternative for imaging the breast and the heart comparing to conventional SPECT. The aim …
