Patent

CA 2383122

The invention relates to a method of imaging a target organ in a patient by SPECT, by using a gamma camera having a gamma detector, and by computer reconstructing the distribution of the radioactivity inside the patient's body from planar images, acquired along at least one linear orbit performed in a transverse direction, wherein said gamma detector is perpendicularly provided on its outer surface with a plurality of collimator septa in a mutually parallel arrangement and with at least one raised wall, extending in the longitudinal direction of the detector, transversely positioned to said septa and with a substantial portion extending beyond said septa, said wall and said septa together forming a so-called rake collimator. The invention further relates to said rake collimator as such and to a combination of a gamma detector and a rake collimator. The invention also relates to an equipment for performing the above method.

L'invention concerne un procédé d'imagerie d'un organe cible d'un patient par gammaphotographie (SPECT), à l'aide d'une gamma-caméra possédant un gamma-détecteur, et par reconstruction informatique de la distribution de la radioactivité dans le corps dudit patient à partir d'images planaires, acquises au moins le long d'une orbite linéaire exécutée dans un sens transversal. Le gamma-détecteur est équipé, perpendiculairement à sa surface extérieure, de plusieurs septa de collimateur agencés parallèlement, et d'au moins une paroi dressée s'étendant dans le sens longitudinal dudit détecteur placée transversalement par rapport audits septa, et d'une partie substantielle s'étendant au-delà des septa, ladite paroi et les septa formant ensemble un collimateur Rake. L'invention concerne également ledit collimateur Rake en tant que tel, et une combinaison de gamma-détecteur et de collimateur Rake. L'invention concerne enfin un équipement permettant de mettre en oeuvre le procédé ci-dessus.
