Abstract: To provide a technology that can easily acquire body weight information of a patient. A processing part that deduces the body weight of a patient based on a camera image of the patient lying on a table of a CT device, including a generating part that generates an input image based on the camera image, and a deducing part that deduces the body weight of the patient when the input image is input into a learned model. The learned model is generated by a neural network executing learning using a plurality of learning images C1 to Cn generated based on a plurality of camera images, and a plurality of correct answer data G1 to Gn corresponding to the plurality of learning images C1 to Cn, where each of the plurality of correct answer data G1 to Gn represents a body weight of a human included in a corresponding learning image.

Abstract: An X-ray CT system comprises: a storage device for storing therein a referential emission condition defined assuming at least one of a required referential width and a required referential body depth in a subject and defined taking account of a degree of X-ray absorption in the subject; a camera and a distance sensor for detecting a width and a body depth of the subject; and an emission condition setting section 76 for setting an emission condition for X-rays emitted by an X-ray tube in imaging after correcting the referential emission condition according to at least one of a difference between the detected width of the subject and the referential width and a difference between the body depth of the subject detected by the optical sensor and the referential body depth.
