Abstract: An X-ray collimator for collimating X-rays from an X-ray source that illuminate an array of columns and rows of X-ray detectors, the collimator having a first side that faces the X-ray source and a second side opposite the first side that faces the detector array, the collimator comprising: a plurality of strips formed from an X-ray absorbing material, wherein each strip is corrugated so that it has rectangular and/or square corrugations; and means for maintaining the plurality of strips one next to the other with the corrugations of one strip aligned with corrugations of an adjacent strip to form an array of rows and columns of square/and or rectangular wells corresponding to the X-ray detectors in the array.
