Definitions
- the present invention relates to a tomographic imaging system and method.
- Intraoperative visualization of target lesions and overlying tissues can reduce the time and invasiveness of surgical procedures, which results in cost savings and reductions in surgical complications .
- the present invention contemplates a tomographic imaging system comprising a moveable detector that is capable of detecting gamma radiation; a position sensor for determining the position and angulation of the detector in relation to a gamma ray emitting source; and a computational device for integrating the position and angulation of the detector with information as to the energy and distribution of gamma rays detected by the detector and deriving a three dimensional representation of the source based on the integration.
- Figure 6B shows a formalism that converts rays from a moving pinhole into the equivalent of the dual detector geometry depicted in Figure 6A.
- Boundary planes 88 and 96 are defined, which are traversed by rays passing through the pinhole 84.
- the detector backplane 82 is beyond the volume of reconstruction.
- the event origin on the detector backplane 82 is backprojected onto the boundary 88 of the reconstruction volume 90.
- the location of intersection 92 with this boundary 88 is then treated as if the ray actually arose from this location 92 on the boundary volume.
- the event data is treated as if it was from lines which originated and terminated in "virtual" detectors 88 and 96 placed at the boundary locations 92 and 94.

Abstract
L'invention concerne un système d'imagerie tomographique comprenant un ou plusieurs détecteurs mobiles permettant de détecter un rayonnement gamma, un ou plusieurs capteurs de position permettant de déterminer la position et l'angulation des détecteurs par rapport à une source émettrice de rayons gamma, ainsi qu'un dispositif informatique destiné à intégrer la position et l'angulation des détecteurs avec des informations relatives à l'énergie et à la distribution des rayons gamma détectés par les détecteurs et à fournir une représentation en trois dimensions de la source sur la base sur cette intégration. L'invention concerne également un procédé d'imagerie d'une lésion émettrice de rayonnement située dans un volume étudié.
