Processing system of electric signals coming from X-ray detector

Creators

Description

The system includes separated acquisition means of the values of the currents given by the element cells of the detector principal and secondary chambers. It includes, too, processing means to correct secondary chamber current value then to sample these corrected values so as to substract them one by one from current values given by principal chamber cells

Abstract (French)

L'invention concerne un systeme de traitement des signaux electriques issus d'un detecteur de rayons X. Le systeme comprend des moyens d'acquisition separes, des valeurs des courants I, Ic fournis par les cellules elementaires de la chambre principale et de la chambre secondaire du detecteur et des moyens de traitement pour corriger les valeurs des courants Ic fournis par les cellules de la chambre secondaire, puis pour echantillonner ces valeurs corrigees de maniere a les soustraire une a une des valeurs des courants I fournis par les cellules de la chambre principale. Application a la tomographie d'organes
