Single photon emission computed tomography (SPECT) systems are proposed which provide images with improved signal-to-noise ratio. The systems consist of gamma cameras equipped with collimators which view an object to be imaged with an increased sampling density in the vicinity of the center of a field-of-view. The detection systems produce weighted projection data. Evaluation was made with respect to noise characteristics in images resulting from such systems. Simulation studies showed that… CONTINUE READING
