ABSTRACT:
A nuclear medicine diagnosis apparatus comprising a mechanical collimator for effecting passage in a given direction of photons with given energy emitted from an object injected or dosed with a drug containing a radioactive isotope; a former-stage detector for detecting positional information at a point of reaction of photons having passed through the mechanical collimator and information on the momentum of charged particles generated by the reaction; a latter-stage detector disposed in the subsequent stage of the former-stage detector to detect information on the photons having been scattered by the former-stage detector; and image reconstruction means for reconstructing an image from detection information having been collected from the former-stage detector and latter-stage detector, wherein the image reconstruction means is built so that differentiation is carried out on the information on the photons having passed through the mechanical collimator and the information on the photons having been scattered by the former-stage detector and that the image reconstruction is carried out by different image reconstruction algorithms from the individual differentiated detection information.
