A detector capable of securing space for arranging pixels in the vicinity of edges of adjacent readout chips according to design of counting circuits. A 2-dimensional hybrid pixel array detector configured to detect radiation rays, including a detection unit configured to detect the radiation rays incident in a region of each pixel, and a plurality of the readout chips including counting circuitsrespectively connected to each of the pixels, the counting circuitshaving a smaller set pitch than the pixelsalong a certain direction in a detection surface. The regions occupied by the pixels and counting circuits corresponding to the pixels overlapping at least partially, and the connection being made in the overlapping regions.

Detector

An image processing method and an image processing apparatus which remove the effects of cosmic rays, noise and defective pixels without losing data in a specified time and which can correct image data efficiently and with high accuracy are provided. An image processing method of performing correction processing on an abnormal value of X-ray image data is provided which includes the steps of: (S) determining whether or not there exists a target element with intensity significantly different from intensity of peripheral elements, in a three dimensional space formed with a space axis and a time axis defined by a series of captured image frames; and (S) replacing the intensity of the target element with a replacement value calculated from the intensity of peripheral elements.
