PROBLEM TO BE SOLVED: To improve the performance of an imaging data acquisition circuit over a wide range of energy input condition in a data acquisition circuit of an imaging system such as a CT system. SOLUTION: An adaptive data acquisition circuit (26) includes an amplifier (14) for amplifying electrical pulses generated by a detector (12) responsive to energy incident at the detector. The adaptive data acquisition circuit (26) also includes a counting circuit (28) for counting amplified electrical pulses generated by the amplifier (14). In addition, the adaptive data acquisition circuit (26) includes a digital logic circuit (30) for determining a pulse parameter indicative of a pulse rate and an amount of energy present in the amplified electrical pulses and for generating a control signal (34) responsive to the pulse parameter for controlling an operating parameter of the data acquisition circuit (26).
