  • Patent number: 10413270
    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.

  • Patent number: 6509950
    Abstract: A preexposure apparatus comprises a film supply station ST1 for arranging a film cartridge 14 containing a film 12 accommodated therein, a film-drawing station-ST3 for automatically drawing the film 12 over its entire length, an exposure station ST5 for exposing a predetermined portion of the drawn film 12 with an image by the aid of an exposure section 32, a winding station ST6 for automatically rewinding the film 12 after the exposure into the film cartridge 14, and a withdrawing station ST8 for withdrawing the film cartridge 14. Accordingly, the predetermined portion of the film can be preexposed with a desired image automatically and efficiently.
