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.

Abstract: The problem to be solved is to utilize an analysis result of a medical image that uses post-processing function to achieve a higher diagnosis accuracy. The medical image processing apparatus according to the present embodiment includes an acquirer that acquires a first medical image information which is a result of an external processing performed on a second medical information including a medical image, a receiver that receives a selected action for the first medical image information, and a register that associates and registers an action information about the selected action for the first medical image information with the first medical image information.

Abstract: According to one embodiment, an X-ray mammography apparatus includes a breast support, a compression plate, and a compression controller. The breast support where the breast is placed. The compression plate is arranged such that the breast is sandwiched between the breast support and the compression plate. The compression controller is configured to control the breast support to move toward the compression plate so as to compress the breast from below between the breast support and the compression plate.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry is configured to specify a position of a pathological abnormality candidate and a pathological abnormality type of a breast of a subject from a plurality of pieces of tomographic images obtained by performing tomosynthesis imaging on the breast. The processing circuitry is configured to, in a two-dimensional image obtained by performing X-ray imaging on the breast, perform image processing on a position corresponding to the position of the specified pathological abnormality candidate in accordance with the pathological abnormality type.

Abstract: A medical image diagnostic apparatus according to an embodiment includes a compression plate, an X-ray tube, an arm, an X-ray detector, and an ultrasound probe. The compression plate compresses a breast of a subject. The X-ray tube radiates X-rays. The arm holds the X-ray tube and moves, while the X-ray tube radiating the X-rays, an irradiation region of the X-rays in a direction perpendicular to a front-rear direction of the compression plate. The X-ray detector detects the X-rays having passed through the breast of the subject. The ultrasound probe transmits and receives an ultrasound wave, the ultrasound probe being movable in the direction perpendicular to the front-rear direction of the compression plate.

Abstract: A mammography apparatus has a determination unit, a setting unit, a generating unit and a display unit. The determination unit determines whether a radiographic image of a breast contains an implant part based on a pixel value distribution in a predetermined region concerning data of the radiographic image. The setting unit changes a setting of a parameter for a tone conversion process based on a determination made by the determination unit. The generating unit generates a display image based on the radiographic image by application of the parameter. The display unit displays the display image.
