    {
	The finite width of the X-ray beam determined by the source
	and detector aperture limits the resolution of
	computed tomography (CT) images.
	Improved resolution can be obtained
	by reducing the width of the detector,
	but at a cost in dose utilization efficiency.
	We show that it is possible to improve the resolution of a CT image
	with a minimum cost in dose efficiency by varying the sensitivity
	(apodizing) the detector response function.
	Further, we demonstrate how to construct detectors with nonuniform
	response by changing the reflective coating on the scintillator.
	Finally, we show improved calculated point response functions for such
	modified detectors.
