  • Publication number: 20170295300
    Abstract: An image processing apparatus comprises processing circuitry. The processing circuitry is configured to acquire a first image in which each pixel is expressed with a first gradation. And the processing circuitry is configured to specify a partial region in the first image. And the processing circuitry is configured to convert, based on correspondence information that associates each level of the first gradation with a display pattern of a plurality of pixels in a display, the level in the first gradation of each pixel included in the partial region in the first image into the corresponding display pattern, the display displaying the display pattern with a second gradation having fewer levels than the first gradation. And the processing circuitry is configured to generate a second image that expresses a plurality of pixels included in the partial region of the first image as the converted display patterns.

  • Publication number: 20170181720
    Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an imaging apparatus, processing circuitry and permission input circuitry. The imaging apparatus includes an imaging system performing X-ray imaging of an object, and a bed on which the object is placed. The processing circuitry accepts an instruction to cause the imaging apparatus to perform a operation, and notifies a content of the operation relating to the accepted instruction to a first user. The permission input circuitry accepts information indicating permission of the operation from the first user who has confirmed the content of the operation. The processing circuitry causes the imaging apparatus to perform the operation to more severely restrict the operation compared with after acceptance of information indicating permission of the operation by the permission input circuitry, until the acceptance of information indicating permission of the operation by the permission input circuitry.
