Abstract
A method and apparatus of obtaining and reconstructing an image of a portion of a body, administered by a radiopharmaceutical substance, by using Single-photon emission computerized tomography (SPECT) for determination of functional information thereon. The method comprises (a) acquiring gamma ray photons emitted from said portion by means of a detector capable of converting the photons into electric signals, the detector having at least one crystal and allowing said gamma rays having incident angles essentially exceeding 5 degrees and, preferably, exceeding 10 degrees to be detected; (b) processing said electric signals by a position logic circuitry and thereby transforming them into data indicative of positions on said photon detector crystal, where the photons have impinged the detector; and (c) reconstructing an image of a spatial distribution of the pharmaceutical substance within the portion of the body by processing said data and taking into consideration weight values which are functions of angles and, possibly, distances between different elements of the portion of the body and corresponding elements of this position's projection on the detector.
