PROBLEM TO BE SOLVED: To simplify a controller necessary to take out X-ray detection signals and to select pixel data in collecting part of pixel data, and in addition, to prevent detection operation of X-ray detection elements from becoming unstable.
SOLUTION: Even when a two-dimensional X-ray detector 2 collects part of pixel data, X-ray detection signals are taken out from all of the X-ray detection elements 8 by an all detection signal take-out mechanism, and in addition, all of pixel data are read out from an FIFO-type storage mechanism 19 by the controller 20 to select only pixel data of collecting objects by a pixel data selection output part 23. Therefore, the structure of the controller is simplified which is necessary to take out the X-ray detection signals and to selectively output pixel data. Further, X-ray detection signals are taken out from all of the X-ray detection elements 8, and resultantly, it is not feared that the existence of detection elements 8, which are not collecting objects of the pixel data, becomes a destabilizing factor to the detection operation of detection elements 8 which are the collecting objects of the pixel data.
