Abstract :
The aim of this paper is to describe a very general readout system for one-dimensional ionizing particle detectors. This system is based on a VME (Versa Module Eurocard, IEEE P1014, Mar. 12, 1987) bus which allows us to read and store up to 1000 channels in 1 ms. Thus, two-dimensional images can be recorded in a short time, for example by moving the measurement device composed of the detectors and their onboard electronics. This concept has been applied to a new low-dose X-ray radiology apparatus. A direct numerical radiographic image obtained with this system is presented
