摘要： An apparatus including a scintillator panel which absorbs X-rays radiated from an X-ray generator and converts the X-rays into visible light; an image detector including a plurality of pixels arranged in a matrix array and charging the plurality of pixels with electric charges proportional to intensity of the visible light converted by the scintillator panel; a gate driver which selects a line in the image detector and applies a drive signal to pixels in the selected line; an automatic exposure request signal generator which generates an automatic exposure request signal as a trigger signal informing of X-ray radiation through detection of X-rays radiated from the X-ray generator; and a controller which controls a time point of performing an exposure operation depending on a state of the drive signal applied to the pixels of the selected line in response to the automatic exposure request signal is disclosed.
摘要翻译：一种装置，包括：闪烁体面板，其吸收从X射线发生器射出的X射线，并将X射线转换成可见光; 图像检测器，包括以矩阵阵列排列的多个像素，并且以与由闪烁体面板转换的可见光的强度成比例的电荷对多个像素进行充电; 栅极驱动器，其选择图像检测器中的线，并将驱动信号施加到所选择的线中的像素; 自动曝光请求信号发生器，其通过检测从X射线发生器辐射的X射线产生作为通知X射线辐射的触发信号的自动曝光请求信号; 公开了一种控制器，其根据自动曝光请求信号控制根据施加到所选行的像素的驱动信号的状态进行曝光操作的时间点。

摘要： The present disclosure provides an X-ray imaging apparatus and method. When capturing an X-ray image using an automatic exposure request signal generated through detection of X-rays emitted from an X-ray generator, the X-ray imaging apparatus and method may verify validity of the automatic exposure request signal, thereby preventing unintentional generation of the automatic exposure request signal due to vibration, temperature change, noise, etc.
摘要翻译：本公开提供了一种X射线成像装置和方法。当使用通过从X射线发生器发射的X射线的检测而产生的自动曝光请求信号来拍摄X射线图像时，X射线成像装置和方法可以验证自动曝光请求信号的有效性，从而防止意外产生由于振动，温度变化，噪音等自动曝光请求信号
