Abstract
A method is disclosed for determining the intensity of ionizing radiation using a detector with a multiplicity of direct-conversion detector elements, in particular for use in a CT system. In at least one embodiment, the method includes supplying the signal pulses to a preamplifier/signal conditioner, supplying the amplified and conditioned signal pulses to two pulse-height discriminators connected in parallel or in series, registering by a combination logic, and transmitting the registered signal pulses to a counter. In at least one embodiment, provision is made for feedback, by which, firstly, the pulse shape of the signal pulses and, secondly, the clock rate of the clocked pulse-height discriminator are set as a function of the signal frequency. Furthermore, at least one embodiment of the invention relates to a circuit arrangement for measuring signals of a direct-conversion detector, in particular for use in a CT system, by which the method according to at least one embodiment of the invention can be carried out.
