Problems solved by technology

However, the method of image reconstruction used by Compton cameras is fundamentally ambiguous.
This ambiguity explains why the Compton images often show artefacts in addition to real sources, which complicates interpretation of the images.
This well-known solution of the prior art has the disad...

Embodiment Construction

[0021]In general, as introduced in its above preamble, the present application proposes to use “Compton images” from different positions of “Compton captures”. The term “Compton image” (or simply “image”) refers in the present application to the imaging obtained from vectors calculated on the basis of data collected by a single, given “capture centre” (having a given position, whatever its technical specifications). On the other hand, the term “Compton capture” (or simply “capture”) refers in the present application to the imaging obtained from vectors calculated on the basis of data collected by a plurality of given “capture centres”, whether it is a question of the same capture centre moved in space between two successive images, or two separate capture centres (CC1, CC2) which produce independent images from different positions. The present application therefore provides various embodiments for its physical implementation in terms of device, system or method. Thus, the same camer...

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.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present application relates to the field of imaging and more particularly imaging of gamma-ray sources. In particular, the present application concerns a device, system and methods of imaging by detector of the Compton camera type.[0002]More precisely, the present application concerns a device, system and methods of imaging by so-called “multi-capture” (at least “bi-capture”) Compton camera, that is, using at least two Compton imaging captures carried out from at least two different sites (whether different sites of the same Compton camera or different sites of a plurality of separate Compton cameras). The present application therefore details a new technology of detection of gamma rays combining a plurality of Compton image captures and improvements made to the cameras and / or methods of image reconstruction using this type of multiple captures. The invention further concerns the use of such imaging and / or detection in the fields in particul...
