  • Publication number: 20250072857
    Abstract: An X-ray diagnosis apparatus according to one embodiment includes an imaging system, a display, processing circuitry and system control circuitry. The imaging system includes an X-ray tube that generates an X-ray, an X-ray diaphragm that restricts an irradiation range of the X-ray, an X-ray detector that detects the X-ray, and a couch on which a subject is to be laid for irradiation with the X-ray. The display displays an X-ray image with numerical values indicating positions on the X-ray image generated by X-ray imaging of the subject by the imaging system. The processing circuitry recognizes a numerical value based on a collected user's utterance with respect to the numerical values. The system control circuitry performs control of the imaging system in accordance with a position indicated by the recognized numerical value among the numerical values.

  • Publication number: 20240407744
    Abstract: An X-ray diagnosis apparatus includes: an X-ray; an X-ray detector; processing circuitry configured to generate an X-ray image based on the detected X-rays, and causes a display to display the X-ray image; a first operator that receives an operation of inputting a central position for a displayed image to be displayed on the display; and a second operator that receives an operation of inputting a field-of-view size of the displayed image in a stepless manner. The processing circuitry is configured to change the field-of-view size of the displayed image in response to an operation at the second operator, while the central position of a current displayed image is being maintained.

  • Publication number: 20240307011
    Abstract: A console device according to an embodiment includes an operation assembly, a display section, and processing circuitry. The operation assembly includes a plurality of operation sections configured to designate a position of each of four X-ray aperture blades included in an X-ray aperture that limits an irradiation range of an X-ray with which a subject is irradiated from an X-ray tube. The display section is configured to indicate a first irradiation range formed by the X-ray aperture. The processing circuitry is configured to control, according to an operation on the operation assembly, a position of a corresponding X-ray aperture blade and cause the X-ray aperture to form a second irradiation range.

  • Publication number: 20230248324
    Abstract: An X-ray diagnostic apparatus according to an embodiment includes a couchtop, an irradiation unit, a support member, a first opening, and an X-ray detector. The couchtop is a component on which a subject is placed. The irradiation unit outputs X-rays from above the subject. The support member supports both ends of the couchtop in the lateral direction from below and forms a gap between the support member and the couchtop in a center part corresponding to an area excluding both ends. The first opening is formed at either one or both of the ends of the couchtop in the longitudinal direction and is accessible to the gap. The X-ray detector is provided in the gap through the first opening and detects the X-rays.

  • Patent number: 9978163
    Abstract: An exposure management system according to an embodiment includes a processing circuitry. The processing circuitry is configured to calculate a deviation index related to a difference between a target exposure index indicating an index of an exposure value that is set as a target of an X-ray image taking process and an image-taking-period exposure index indicating an index of an exposure value observed during the X-ray image taking process. The processing circuitry is configured to control so as to cause a display device to display history information from a predetermined time period indicating at least one selected from between image-taking-period exposure indices and deviation indices.
