(FR) SELECTION DE L'EPAISSEUR D'UNE IMAGE DANS UN SYSTEME DE FORMATION D'IMAGES MULTICOUPE
Abstract
(EN)
Scalable multislice systems which, in one embodiment, include a scalable multislice detector, a scalable data acquisition system (SDAS), scalable scan management, control, and image reconstruction processes, and a user interface, are described. More specifically, the user interface is implemented in a host computer for defining the configuration of the imaging system. Particularly, after selection of each scan parameter, the user interface displays the available scan parameter values for the remaining parameters so that the scan objectives are met. More specifically, after selection of each scan parameter, the user interface updates the remaining scan parameters, including prospective and retrospective image thicknesses. Axial scan, helical scan and cine scan modes are possible; a cam collimator is positioned between the X-ray source and the detectors.

L'invention concerne des systèmes multicoupe à échelle modifiable qui, dans un mode de réalisation, comprennent un détecteur multicoupe à échelle modifiable, un système d'acquisition de données à échelle modifiable, des processus de gestion de balayage, de commande et de reconstruction d'images à échelle modifiable, et une interface utilisateur. Plus spécifiquement, on installe l'interface utilisateur dans un ordinateur hôte pour définir la configuration du système de formation d'images. En particulier, après la sélection de chaque paramètre de balayage, l'interface utilisateur affiche les valeurs du paramètre de balayage pour les paramètres restants de sorte que les objectifs de balayage soient atteints. Plus spécifiquement encore, après la sélection de chaque paramètre de balayage, l'interface utilisateur met à jour les paramètres de balayage restants, y compris les épaisseurs prospective et rétrospective des images. Il est possible d'effectuer des balayages en mode axial, hélicoïdal ou vertical en positionnant un collimateur à came entre la source de rayons X et les détecteurs.
