Problems solved by technology

[0015] However, a problem with the non-linear trigger type X-ray imaging device is that X-rays are emitted regardless of the state of the X-ray imaging device
[0016] That is, when X-rays are emitted for X-ray imaging in a very short period of time under the unsteady state of the image detector of the X-ray imaging device, the X-ray imaging device cannot generate an effective automatic exposure request signal or Inability to obtain high-quality X-ray images

Abstract

Provided are an X-ray image photographing apparatus and a method thereof. The X-ray image photographing apparatus and the method thereof according to the present invention verify the effectiveness of an automatic exposure request signal in detecting the X-rays radiated from an X-ray generator and photographing an X-ray image using the self-generated automatic exposure request signal, thus preventing an undesired automatic exposure request signal from being generated by vibration, temperature change, noise or the like and thus improving the reliability of an X-ray photographing operation and an photographed X-ray image.

Description

technical field [0001] The present invention relates to an X-ray imaging apparatus and method, and more particularly, to an X-ray imaging apparatus and method, and more particularly, to a method for automatically An X-ray imaging apparatus and method capable of improving the reliability of X-ray imaging operations by requesting the validity of a signal. Background technique [0002] Generally speaking, an X-ray diagnostic apparatus includes an X-ray generator that generates X-rays and emits the X-rays to a target, and an X-ray imaging device that captures images of the X-rays penetrating the target. image. [0003] The X-ray imaging device of such an X-ray diagnostic apparatus sequentially performs a flushing operation for flushing out dark current accumulated in an internal image sensor of each unit row, an exposure operation for absorbing X-rays emitted by an X-ray generator , and a readout operation for allowing the X-ray imaging apparatus to read charges generated by e...
