  • Publication number: 20240398491
    Abstract: In one embodiment, an X-ray diagnostic apparatus can communicate with a controller configured to operate a catheter robot capable of moving an inserted device within the object and comprises a display and processing circuitry. The display is configured to display at least one fluoroscopic image of an object. The processing circuitry is configured to receive a control signal indicating a content of an operation on the catheter robot from the controller, acquire a plurality of fluoroscopic images of the object by irradiating the object with X-rays, control X-ray irradiation to the object, cause the display to display the plurality of fluoroscopic images to be sequentially acquired when the X-ray irradiation is performed, generate a plurality of reproduced images based on the plurality of fluoroscopic images acquired before a stop of the X-ray irradiation and cause the display to display the plurality of reproduced images when the X-ray irradiation is stopped.

  • Publication number: 20230346333
    Abstract: The X-ray imaging apparatus according to the embodiment includes an X-ray irradiator and processing circuitry. The X-ray irradiator is placed in a surgery room. The processing circuitry is configured to sequentially acquire a position of each staff member presenting in the surgery room during a procedure using the X-ray irradiator. The processing circuitry is configured to sequentially acquire an exposure dose of each staff member from a dosimeter. The processing circuitry is configured to associate the position of each staff member and the exposure dose of each staff member with a time, and sequentially record association data in a memory circuit. The processing circuitry is configured to display association data indicating a relation between the position of each staff member and the exposure dose of each staff member in an identifiable manner on a display.

  • Patent number: 9384545
    Abstract: An X-ray image diagnosis apparatus according to an embodiment includes: an image processing unit configured to create a synthesized image by synthesizing an X-ray image of a region of interest inside a given region and an X-ray image of a peripheral region excluding the region of interest in the given region, wherein when the region of interest is changed, the image processing unit acquires an X-ray image of a changed region which is in the region of interest before the change and is changed to the peripheral region, from the X-ray image of the region of interest before the change, and then superimposes the X-ray image of the changed region on the X-ray image of the peripheral region to create the synthesized image.
