摘要： An x-ray image detector monitors the intensity of incident x-rays to detect an end of radiation from an x-ray source when the x-ray intensity decreases to a threshold level or less. The x-ray intensity gets down to zero with a variable time lag from the start of decreasing, called radiation wave tail. Depending on the gradient of declivity in time curve of the decreasing x-ray intensity, calculated at the time when the end of radiation is detected, the x-ray image detector decides a delay time from the end-of-radiation detection time to a reading start time to start reading signal charges from the image detector. Thus, the reading start time may be adjusted to the point when the x-ray intensity gets down to zero, which will improve S/N ratio and prevent shading artifacts.
摘要翻译：当X射线强度降低到阈值水平或更低时，X射线图像检测器监测入射的X射线的强度以检测来自X射线源的辐射的结束。 X射线强度从减小开始的可变时间滞后变为零，称为辐射波尾。根据在检测到辐射结束时计算出的x射线强度减小的时间曲线下的倾斜度的梯度，X射线图像检测器决定从放射检测结束时间到延迟时间的延迟时间读取开始时间开始从图像检测器读取信号电荷。因此，可以将读取开始时间调整为当x射线强度降至零时的点，这将提高S / N比并防止遮蔽伪像。

摘要： A flat panel detector has an imaging area, in which pixels are arrayed in a matrix and signal lines for reading out electric signals from the pixels are provided, to detect an image of a subject from x-rays which are incident on the imaging area after penetrating the subject. Detective elements are arranged in the imaging area, to output electric signals corresponding to incident x-rays. Based on previously stored sensitivity data on the detective elements, high-sensitivity elements are selected from among the detective elements. The start of radiation and the end of radiation of x-rays toward the imaging area are detected by monitoring the electric signals from the selected high-sensitivity elements, to control operation of the imaging device on the basis of the detected start and end of radiation.

摘要： A method of processing images from an imaging device corrects defective pixels in an image acquired with the imaging device. The method includes a step of acquiring position information about continuous defective pixels from the position information about the defective pixels, a first correcting step of correcting the defective pixels with at least one normal pixel adjacent at least one defective pixels based on the position information about the defective pixels and a second correcting step of correcting the continuous defective pixels with a plurality of normal pixels adjacent at least one continuous defective pixels based on the position information about the continuous defective pixels. The second correcting step relies upon a greater number of normal pixels than the first correcting step to correct the defective pixels in a higher precision than the first correcting step.

摘要： A radiographic imaging method and system use a radiation solid state detector or a flat panel detector (FPD). The method and system enable radiographic imaging to be continued for a while after occurrence of pixel defects that may lower image quality and minimizing adverse effects of the pixel defects. The pixel defects are analyzed in the respective local regions on the detector. A pixel defect correction is not made on local regions where the pixel defect exceeds a given tolerance but these regions are marked on the radiographic image for recognition.

摘要： A radiation detector includes a detection unit, a detection control unit, an image analyzing unit and a determination unit. The detection unit detects radiographic image data by plural pixels that convert applied radiation into electrical signals and store the electrical signals. The detection control unit controls the detection unit so as to determine that radiation has been applied if a read value obtained by reading the electric signals stored in the plural pixels is equal to or greater than a threshold value, and acquire radiographic image data corresponding to radiation that has passed through a subject. The image analyzing unit performs an image analysis with respect to the radiographic image if the read value is equal to or greater than the threshold value. The determination unit determines based on the result of the image analysis whether or not the radiographic image has been detected at an intended timing.
