description A method and an 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 includes acquiring gamma rays from a body by a detector, preferably with wide incident angle exceeding 5-10 degrees, and reconstructing an image of the distribution of a radiating pharmaceutical substance in the body under inspection. The relationship between the detector and the body or the examined portion thereof is generally known. By processing data from the detector while taking into consideration weight values which are functions of angles and optionally distances between different elements of the body and corresponding elements of the relative position of the body and the detector corresponding elements of this position's projection on the detector.
