PCT No. PCT/SE97/01511 Sec. 371 Date May 3, 1999 Sec. 102(e) Date May 3, 1999 PCT Filed Sep. 9, 1997 PCT Pub. No. WO98/13706 PCT Pub. Date Apr. 2, 1998A method and device for detecting and analyzing X-ray radiation with a detector unit which is placed in connection with the X-ray radiation. The detection unit is connected to a processing unit for processing the information which is received from the detection unit. The detection unit is placed directly in the radiation field of the X-ray radiation, and the detection unit is in the form of a matrix or a vector provided with one of more detector elements. The processing unit processes the information which is obtained from each detector element in the detection unit. In addition, a collimator is arranged in front of the detection unit, with the collimator being formed such that the radiation is reproduced substantially in dot form on the detector element.
