DISPOSITIF POUR DETERMINER DES DIFFERENCES D'ABSORPTION LOCALE A L'INTERIEUR D'UN CORPS

Dans un dispositif pour définir des différences locales en absorption de rayonnement à l'intérieur d'un corps, on utilise un faisceau d'électrons enregistreur qui procède à une exploration suivant la largeur du corps. La mesure directe est toujours possible du fait que depuis chaque face d'impact du faisceau d'électrons, un collimateur sélectionne un faisceau élémentaire dans le faisceau de Röntgen. Du fait d'utiliser un faisceau divergent et un détecteur frappé par le rayonnement, on peut effectuer la mesure sans mouvement mécanique au moins pour une seule section corporelle.

Applications include the imaging of radionuclide distributions within the human body or the use of a dual energy source to provide a dual photon bone densitometry apparatus that uses stationary or scanning acquisition techniques.

The image is digitized by the sensor and processed by a controller before being stored as an electronic image. A dual energy X-ray source that delivers two different energy levels provides quantitative information regarding the object being imaged using dual photon absorptiometry techniques.

Radiographic and fluoroscopic imaging system

An imaging system provides rapid transition from fluoroscopic to radiographic imaging mode by maintaining the X-ray tube high voltage, increasing the filament current, allowing X-ray tube current to increase toward the desired radiographic current, and terminating exposure when the desired X-ray dose has been achieved. Rapid transition from radiographic to fluoroscopic imaging mode is provided by reducing x-ray tube high voltage to produce an equivalent fluoroscopic-level X-ray output at high initial current, dropping filament current, and enabling automatic brightness system control of the high voltage. As X-ray tube current drops, ABS correspondingly increases high voltage to maintain the desired output. The imaging system obtains movement-related information by analysing a video signal (such as from fluoroscopic image or an image from an optical camera trained on the patient), or from operator movement requests. The system uses movement-related information to control fluoroscopic pulse ...

Methods for acquiring multi spectral data of an object

A multispectral X-ray imaging system uses a wideband source and filtration assembly to select for M sets of spectral data. Spectral characteristics may be dynamically adjusted in synchrony with scan excursions where an X-ray source, detector array, or body may be moved relative to one another in acquiring T sets of measurement data. The system may be used in projection imaging and/or CT imaging. Processed image data, such as a CT reconstructed image, may be decomposed onto basis functions for analytical processing of multispectral image data to facilitate computer assisted diagnostics. The system may perform this diagnostic function in medical applications and/or security applications.
