PROBLEM TO BE SOLVED: To facilitate the correction of a data collection system gain which is not regulated by the slice thickness of a detector by generating a data collection gain coefficient based on a parameter of the monitored data collection system and modulating the data collection gain using the data collection gain coefficient. SOLUTION: A data collection system (DAS) 32 in a control mechanism 26 samples analog data from a detector element 20 so as to convert it into a digital signal, an image reconstitution device 34 executes a high-speed image reconstitution, and a computer 36 stores an image in a mass storage device 38. The computer 36 receives a command and a scan parameter via a console 40 and provides a control signal and information to the DAS 32, an X-ray controller 28, and a gantry motor controller 30. A data collection gain coefficient is generated based on the parameter of the monitored data collection system and the data collection gain is modulated using the data collection gain coefficient. |
