Tacography equipment for studying patients to whom radioactive products have been administered

Creators

Description

This invention relates in a general way to positron emission tacography (computer controlled axial tomography), and more exactly, to a data acquisition system enabling the number of background noise signals due to random coincidences to be very accurately determined. The extraction of this background noise from the total number of coincidences is assured by this invention. This operation is either carried out practically instantaneously or later on. The input circuits used enable the equipment to function with an almost zero dead time

Abstract (French)

La presente invention concerne de facon generale la tacographie (tomographie axiale commandee par ordinateur) a emission de positons et plus precisement un systeme d'acquisition de donnees qui permet une determination tres precise du nombre de signaux de bruit de fond dus a des coincidences aleatoires et qui assurent la soustraction de ce bruit de fond du nombre total de coincidences detectees, soit de facon pratiquement instantanee soit de facon retardee. Des circuits d'entree permettent un fonctionnement pratiquement sans temps mort
