Abstract

To prevent an increase in the temperature of an X-ray detector while avoiding an increase in the size of the X-ray detector resulting from a cooling unit being attached thereto, provided is an X-ray diagnostic system which has an X-ray irradiation means for applying X-rays; an X-ray detector for detecting X-rays having passed through a subject to output image data; and a controller for controlling the X-ray irradiation means and the X-ray detector. The X-ray diagnostic system is adapted to include an exposure preparation state detection means for detecting the state of exposure preparation for taking an X-ray radiograph of the subject; and a power switching section for turning on a power supply for the X-ray detector or turning off the activated power supply in response to a detected result provided by the exposure preparation state detection means.

Description

technical field [0001] The present invention relates to an X-ray image diagnostic device and an X-ray detector, and particularly relates to suppression of a temperature rise of the X-ray detector. Background technique [0002] Currently, devices that irradiate an object with radiation and detect the intensity distribution of the radiation transmitted through the object to obtain a radiographic image of the object are widely used in the field of industrial nondestructive inspection or medical diagnosis. As a general method of such imaging, there is a film / screen method for X-rays. In recent years, due to the advancement of digital technology, a method of converting radiographic images into electrical signals, performing image processing on the electrical signals and replaying them as visible images on a CRT or the like is required to obtain high-quality radiographic images. In addition, with the advancement of semiconductor process technology, devices that similarly capture ...
