Abstract [en]

The invention relates to a method and an apparatus for simplified alignment in scanned slot x-ray imaging. The apparatus has a first collimator (102) and a second collimator (104) arranged in a first distance (a) and a second distance (b), respectively, from a radiation source (100). Each collimator is provided with a slot (102a, 104a) and a detector (106) is located under the second collimator slot, said slot of said second collimator being wider than the said slot of said first collimator and said detector under the second slot is wider than the first collimator slot and the second collimator slot. The slot (104a) of said second collimator has a width (y') not less than a safety margin and the product of the width (x) of the slot (102a) of said first collimator (102) and said second distance (b) divided with the said first distance (a) for allowing a misalignment with respect to a central symmetry line (105) of said slots (102a, 104a).
