ABSTRACT:
A collimator blade assembly for a computed tomographic X-ray scanner comprising a blade of X-ray beam stopping material having an aperture for passing X-rays and an X-ray penetrable member closing at least a portion of that aperture to reinforce the material and thereby minimize collimator blade/detector clearances while preventing undesirable collimator blade vibration.
