Camera compton multi-capture et procede d'imagerie

Abstract

The present invention concerns a device, system and method of use of a multi-capture Compton camera, characterised by the use of at least two capture centres having separate positions.

1 . A multi-capture Compton camera, comprising at least two capture centres having separate positions. 
     
     
         2 . The multi-capture Compton camera according to  claim 1 , wherein the separate positions are separated by a distance less than or equal to twice the angular resolution of the Compton camera capture centre. 
     
     
         3 . The multi-capture Compton camera according to  claim 2 , wherein the separate positions are separated by a distance less than but close to twice the angular resolution of the Compton camera capture centre. 
     
     
         4 . The multi-capture Compton camera according  claim 2 , wherein the separate positions are disposed along an arc centred on the position of the gamma-ray source. 
     
     
         5 . A multi-capture Compton camera consisting of two adjacent detection assemblies observing the same field of view, wherein the two detection assemblies are separated by an angular distance greater than 1° at the maximum range of the camera in order to make it possible to observe displacement of a point source at the maximum range between two images taken simultaneously. 
     
     
         6 . The multi-capture Compton camera according to  claim 1 , wherein the same effect is produced by a precisely known relative movement of the camera between two shots, the position of the optical axis of the camera also being known. 
     
     
         7 . A method of estimating the distance from a radioactive source by triangulation of gamma rays utilizing a camera to estimate the distance from a radioactive source by triangulation of gamma rays. 
     
     
         8 . The method according to  claim 6  further comprising eliminating artefacts, preserving only the points which are preserved between the two images (coherent distance). 
     
     
         9 . The method according to  claim 6  further comprising utilizing the camera to detect and produce an image of very weak sources of <0.1 microrad/h with certainty. 
     
     
         10 . The method according to  claim 6  further comprising reconstructing utilizing a multi-capture camera which consists of considering, for the reconstruction, only the intersections of cones arising from camera C 1  with those arising from camera C 2 .
