X-ray imaging apparatus and operation method of x-ray imaging apparatus

Abstract

Provided is an X-ray imaging apparatus including two tubes, the X-ray imaging apparatus having a smaller exposure amount of a subject than a biplane X-ray imaging apparatus, maintaining an image quality of an X-ray image in a time axis direction, and improving the visibility of a device or the like. A first X-ray tube that irradiates the subject with X-rays, a second X-ray tube that irradiates the subject with X-rays from a direction different from a direction of the first X-ray tube, and one X-ray detector that detects the X-rays that are applied from the first X-ray tube and the second X-ray tube and are transmitted through the subject are provided. Pulse-like power is alternately supplied to the first X-ray tube at a first pulse width and to the second X-ray tube at a second pulse width such that a period in which the first X-ray tube applies the X-rays and a period in which the second X-ray tube applies the X-rays do not overlap with each other. A first X-ray image is generated by taking in output of the X-ray detector that has detected the X-rays applied from the first X-ray tube. A second X-ray image is generated by taking in output of the X-ray detector that has detected the X-rays applied from the second X-ray tube.
