Abstract
According to one embodiment, a medical image diagnostic apparatus includes a holding device, a driving unit, a first encoder, a second encoder, and processing circuitry. The holding device holds an X-ray generator and an X-ray detector such that the X-ray generator and the X-ray detector are rotatable. The driving unit transmits a rotating force of a driving motor to a rotation axis through a power transmission mechanism. The first encoder detects a rotation of the driving motor. The second encoder detects a rotation of the rotation axis. The processing circuitry detects an abnormal state of the power transmission mechanism, based on a time difference between a first pulse output from the first encoder and a corresponding second pulse output from the second encoder.
