Abstract: Es sind ein Verfahren zur Abbildung eines Patienten und ein Röntgendosimetriesystem geschaffen. Das Röntgendosimetriesystem enthält eine Lagerungsplattform, die eingerichtet ist, um ein abzubildendes Objekt zu lagern, und ein digitales Röntgendosimeter, das auf einer Oberfläche der Lagerungsplattform montiert ist, wobei das Röntgendosimeter eingerichtet ist, um einfallende Strahlung zu empfangen, bevor die einfallende Strahlung durch das abzubildende Objekt hindurchgetreten ist, wobei das Röntgendosimeter eine Dicke von weniger als etwa vier Millimeter aufweist.

Abstract: A system and method for monitoring a subject are presented. The system includes a sensing device including at least one magnetic source to generate a magnetic field and an array of magnetic sensors disposed within the magnetic field. The sensor array obtains a plurality of magnetic field measurements at a plurality of locations along a vessel carrying a fluid including one or more magnetic particles. Further, the system includes a processing subsystem communicatively coupled to the sensing device, where the processing subsystem determines variations in the measurements caused by magnetization-relaxation of the magnetic particles based on a coupled model that defines behavior of the fluid in the varying magnetic field based on principles of magnetization-relaxation, bulk motion of the magnetic particles towards a determined gradient of the magnetic field, magnetostatics, and conservation of momentum. The processing subsystem estimates values of one or more desired parameters based on the determined variations.

Abstract: Dispositif de détection (33) à double fonction, fonctionnant soit en mode de fonctionnement normal soit en mode à correction de PEM afin de supprimer des effets de PEM à l'intérieur du détecteur (33). Le dispositif de détection (33) peut être un détecteur de rayons X à panneau plat utilisé dans des systèmes d'imagerie radiographique. Le dispositif a une architecture de pixels et une technique de lecture de panneau permettant une mesure en temps réel, à une fréquence spatiale élevée, du bruit induit par le rayonnement électromagnétique sur un détecteur numérique (33) de rayons X. La mesure peut servir à étalonner en temps réel le détecteur pour parvenir à une imagerie sans artefacts dans tous les environnements, dont ceux qui contiennent des champs électromagnétiques variant dans le temps et dans l'espace.

Abstract: Détecteur numérique de rayons X comprenant une pluralité de zones de pixels (54). Chaque zone de pixel (54) comporte une première photodiode (86) ayant une première superficie (116) et une seconde photodiode (88) ayant une seconde superficie (122) égale ou inférieure à la première superficie (116). Le détecteur numérique de rayons X comprend également une structure de blindage (94) disposée au-dessus des première (86) et seconde (88) photodiodes de chaque zone de pixel (54), la structure de blindage (94) isolant proportionnellement une plus petite partie de la première photodiode (86) que de la seconde photodiode (88) afin de doter la première photodiode (86) d'une première sensibilité et la seconde photodiode (88) d'une seconde sensibilité inférieure à la première sensibilité.
