  • Publication number: 20240081770
    Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a plurality of projection data based on an output signal from an X-ray detector that rotates around a subject, performs reconstruction filter processing on the plurality of acquired projection data, the reconstruction filter processing being included in reconstruction regarding the plurality of projection data, generates correction information on a sensitivity difference area formed in the plurality of projection data due to differences in sensitivity of the X-ray detector, on the basis of a processing result of the reconstruction filter processing, performs correction processing on the plurality of projection data on the basis of the correction information, and performs reconstruction processing including the reconstruction filter processing on the plurality of projection data subjected to the correction processing.

  • Publication number: 20230224568
    Abstract: An inspection device includes a small shutter in an opening of an inspection chamber, and a large shutter behind the small shutter. The small shutter has a closed state, an inward-open state, and an outward-open state. The small shutter in the inward-open or outward-open state is pushed by a workpiece and pivots inward in or outward from the inspection chamber. The large shutter has a light-shielding state, a driven state, and a stationary state. The large shutter in the light-shielding state overlaps the small shutter in the closed state and closes a clearance between the opening and the small shutter. The large shutter in the driven state is pushed by the small shutter in the inward-open state and pivots with the small shutter. The large shutter in the stationary state is separate from the small shutter in the outward-open state and at a same position as in the light-shielding state.

  • Patent number: 11662356
    Abstract: A sample installation part in which a sample container accommodating a sample to be subjected to biochemical analysis is installed, and consumables installation parts in which consumables to be used for the biochemical analysis are installed are accommodated in an apparatus body of a biochemical analysis apparatus. The apparatus body is provided with an opening part that leads to a sample tray. An instruction receiving unit receives a movement instruction for moving the sample tray from a normal position where the sample installation part is disposed on the opening part side to a consumables replenishment position where the consumables installation parts are disposed on the opening part side. A driving control unit moves the sample tray from the normal position to the consumables replenishment position in a case where the movement instruction is received by the instruction receiving unit.

  • Patent number: 10741271
    Abstract: The test device is configured of a device main body and a mobile terminal. The mobile terminal functions as an operation terminal of the device main body, and a browsing terminal for measurement data. The mobile terminal is connected to the device main body through wireless communication. The device main body wirelessly transmits the measurement data to the mobile terminal. The mobile terminal notifies the device main body of the reception data size of the measurement data. In the device main body, a determining unit collates the reception data size with the transmission data size of the measurement data and determines whether or not the measurement data is normally transmitted. A notifying unit notifies the mobile terminal of a transmission result showing that non-transmitted data is present.
