Abstract: A medical image diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry executes a scan based on a protocol designated by a user. The processing circuitry extracts a candidate protocol to be executed next to the protocol, based on protocol order information in which identification information that indicates each of a plurality of candidate protocols that can be executed starting from a specific protocol, and order information in which each candidate protocol is executed, are correlated with each other. The processing circuitry outputs the extracted candidate protocol.

Abstract: In one embodiment, An X-ray CT apparatus includes: a rotating body and processing circuitry configured to extract an anatomical landmark from a medical image of an object acquired by a first scan, identify a shape of an anatomical site of the object based on the anatomical landmark, and set scanning conditions of a second scan based on the shape of the anatomical site, the second scan including a tilt scan in which a scan is performed under a condition where the rotating body is tilted, the scanning conditions including at least a tilt angle of the tilt scan.
