Definitions

  • the detection of the event 1000 is performed by a radiation detector including a scintillator array 1002 and a photomultiplier tube (PMT) 1004.
  • the event 1000 generates a scintillation event within the scintillator array 1002 to generate light due to the interaction of energy from the event 1000 within the scintillator of the scintillator array 1002.
  • the resulting light is detected by the PMT 1004.
  • the CPU can execute algorithms and computer programs including computer readable instructions that perform the functions described herein.
  • the program can be stored on a variety of media, including non-transitory electronic memory (such as a solid state drive or flash drive) as described above, or a disk drive such as a hard disk, CD or DVD drive. Any of these are included.
  • computer readable instructions include processors such as the Xeon (registered trademark) processor by Intel in the United States and the Opteron (registered trademark) processor by AMD in the United States, as well as Microsoft VISTA, UNIX (registered trademark), and Solaris (registered trademark).

  • the signal received by the processing unit is processed to obtain the energy value of the event and / or the timing of the event.
  • Timing and energy evaluation information is displayed on a display, such as an LCD display, by a display controller. This information is stored locally on the storage device by the storage controller or sent to the networked device by the network controller.
  • An output detection signal from the radiation detector (hereinafter referred to as an output signal) is an electric pulse generated from a detector that detects an event (particle interaction) by receiving radiation.
  • this output pulse is shaped by a filter in order to remove noise in order to accurately count detected events.

Abstract

La présente invention concerne un dispositif de détection de rayonnement comprenant : un compteur servant à estimer le taux de comptage d'événements détectés par un détecteur de rayonnement, l'estimation étant réalisée sur la base d'un signal de sortie provenant du détecteur de rayonnement ; et une unité de commande servant à générer un signal d'ajustement de facteur de réflexion utilisé pour ajuster le facteur de réflexion d'un réflecteur du détecteur de rayonnement, sur la base du taux de comptage estimé, afin d'optimiser la résolution en énergie du détecteur de rayonnement, et à envoyer le signal d'ajustement de facteur de réflexion vers le réflecteur.
