  • Patent number: 10206644
    Abstract: An X-ray imaging apparatus according to the disclosure guides the patient posture using a visual and/or audible interaction device during execution of an X-ray imaging procedure such as mammography, and provides the patient with information about the procedure during the procedure's execution, thereby improving the patient experience while reducing the workload of an operator. The X-ray imaging apparatus may include an X-ray tube, an X-ray detector, and an arm including an upper end within which the X-ray tube is disposed, and a lower end within which the X-ray detector is disposed. An illumination unit may be configured to provide an indication of a movement direction of the arm, responsive to a user input for moving the arm in the movement direction. A controller may control the illumination unit.
