| 摘要 |
<p>The invention relates to efficient single photon emission imaging. A method of shortening acquisition time for obtaining a reconstructed image of a portion (4) of a body (5) of a human patient who was administered with dosage of radiopharmaceutical substance radiating gamma rays, using SPECT (single photon emission computerized tomography), for determination of functional information thereon, comprises the steps of: (a) acquiring photons (3) emitted from said portion (4) of the body (5), by means of a detector (2) capable of converting the photons (3) into electric signals, the electric signals relating to minimal information required for obtaining a meaningful image; (b) processing said electric signals by a position logic circuitry (7) and thereby deriving therefrom data indicative of positions on said photon detector crystal (6), where the photons have impinged the detector (2); and reconstructing an image of a spatial distribution of the pharmaceutical substance within the portion of the body (5) by iteratively processing said data. <IMAGE></p> |
