    摘要: If image data is input to an image processor (step S1), the image processor generates an integrated image sum (step S2). The image processor extracts a maximum output max from the integrated image sum (step S3). The image processor compares the maximum output max with a preset threshold (step S4). In this case, the threshold is set to 80% of the saturation amount. When the saturation amount is 3 V, the threshold is 2.4 V. If the maximum value max is smaller than the threshold, imaging continues. If the maximum value max is equal to or larger than the threshold, the integrated image sum is cleared to 0 (step S5), and a refresh operation is performed.

    摘要: A plurality of correction images are obtained while changing the radiation energy of an incident radiation in the absence of an object. Subsequently, an object image is obtained in the presence of the object by emitting the radiation to the object. Then, the object image is corrected by using a correction image obtained under a radiation energy condition closest to the radiation energy of the obtained object image.

    摘要: At least one exemplary embodiment is directed to a radiography apparatus configured to have an offset reading period, where during the offset reading period an offset reading operation is performed without illumination by radiation (e.g., X-rays). The offset reading period can be different from a radiation (e.g., X-ray) reading period in timings of applying a gate pulse. During the offset reading period, a pixel addition can be performed such that the switching elements corresponding to two or more lines are concurrently turned on-off thus reducing the offset reading period.
