摘要： According to one embodiment, an X-ray diagnostic apparatus includes a holding device and processing circuitry. The holding device movably holds an X-ray generator and an X-ray detector. The processing circuitry generates an X-ray image of the subject, based on an output of the X-ray detector. The processing circuitry sets an interference judgment region between the holding device and an interference object, based on a landmark in the X-ray image. The processing circuitry controls movement of the holding device, based on the set interference judgment region.

摘要： The X-ray diagnostic apparatus includes an X-ray emitting device, an X-ray detection device, a fluoroscopic image generating unit, a calcified region detection unit and a display control unit. The fluoroscopic image generating unit generates a plurality of frames of fluoroscopic images of an object on a basis of detected X-rays in sequence. The calcified region detection unit detects a calcified region on each of the fluoroscopic images in sequence. The display control unit superimposes a calcified region image on a position of the calcified region on each of the fluoroscopic images in sequence, the calcified region image including a calcified region on a pre-acquired CT image or MR image of the object, and displays resulting images on a display device in sequence.

摘要： According to an embodiment, a medical image display apparatus is accessible to an external device that stores data of a plurality of X-ray images with different imaging angles, or includes a storage unit that stores the data of the plurality of X-ray images. The medical image display apparatus includes a display, a distance specifying unit, an image selector and a display controller. The distance specifying unit specifies a distance of a user to the display. The image selector selects, from the plurality of X-ray images, two X-ray images with an angular difference determined based on the distance of the user. The display controller displays the selected two X-ray images on the display for stereopsis by the user.
