Abstract
A data acquisition system includes a charge-sensitive amplifier (CSA) configured to receive a charge from an x-ray detector, the CSA includes a high-gain electronic voltage amplifier, an electrical energy storage device coupled with the amplifier, and an electrical resistor coupled with the amplifier. The data acquisition system includes a baseline sampling circuit configured to receive an output from the CSA and to sample a baseline signal from the CSA, at least one discriminator coupled to an output of the CSA and to an output of the baseline sampling circuit, the at least one discriminator configured to output a voltage if the output of the CSA exceeds a threshold, and a counter coupled to an output of the discriminator and configured to output a digital signal indicative of a photon count received at the x-ray detector and based on the output from the CSA and on the signal from the CSA.
