Abstract
To improve the accuracy of automatic exposure control. [Solution] The medical information processing device according to the embodiment is a medical information processing device that performs X-ray exposure control in a CT imaging system including an X-ray source, and includes a processing unit that acquires scout scan data from a scout scan performed on an imaging target, generates a plurality of view group-based noise images for each slice of the CT imaging system based on the scout scan data, identifies the ROI where the X-ray exposure control is performed, sets the target noise SD of the target by the X-ray exposure control, generates a tube current modulation curve for the ROI based on the plurality of view group-based noise images and the target noise SD, and performs an imaging scan on the imaging target while modulating the tube current applied to the X-ray source based on the tube current modulation curve.
