Title (EN) METHODS AND SYSTEMS FOR STATIONARY COMPUTED TOMOGRAPHY
(FR) PROCÉDÉS ET SYSTÈMES DE TOMODENSITOMÉTRIE STATIONNAIRE
Abstract:
(EN) Methods and systems for stationary computed tomography are disclosed. The methods and systems include a gantry having alternating x-ray sources and x-ray detectors that are stationary during operation of the system. The gantry and pairs of x-ray sources and detectors substantially surrounds an object positioned inside the gantry during operation of the system. Dynamically adjustable collimators are positioned between the x-ray sources and the object. Each of the x-ray sources projects an x-ray beam through the collimators and through the object and the x-ray detectors receive the x-ray beam. The x-ray detectors include means for converting the x-ray beam to raw image data. One or more microprocessors control the x-ray sources and the process raw image data. A data storage device stores instructions, which upon execution by the microprocessor, control the x-ray sources and process the raw image data by converting the raw image data to a digital image.
(FR) L'invention concerne des procédés et des systèmes de tomodensitométrie stationnaire. Les procédés et les systèmes comprennent un portique ayant des sources de rayons x alternées et des détecteurs de rayons x qui sont stationnaires pendant le fonctionnement du système. Le portique et les paires de sources et de détecteurs de rayons x entourent sensiblement un objet positionné à l'intérieur du portique pendant le fonctionnement du système. Des collimateurs réglables de manière dynamique sont positionnés entre les sources de rayons x et l'objet. Chacune des sources de rayons x projette un faisceau de rayons x à travers les collimateurs et à travers l'objet et les détecteurs de rayons x reçoivent le faisceau de rayons x. Les détecteurs de rayons x comprennent des moyens pour convertir le faisceau de rayons x en données d'image brutes. Un ou plusieurs microprocesseurs commandent les sources de rayons x et les données d'image brutes de traitement. Un dispositif de stockage de données stocke des instructions, qui, lors de l'exécution par le microprocesseur, commandent les sources de rayons x et traitent les données d'image brutes en convertissant les données d'image brutes en une image numérique.
