Xenon versus ceramics: a comparison of two CT X-ray detector systems.

Purpose: The purpose of this work was to compare image quality in phantom and patient CT scans acquired by xenon and ceramic CT detector systems.

Method: High and low contrast resolution and image noise were determined with a standard CT phantom for both detector systems. In patient CT images, the effect on image noise was measured in anatomical regions of interest in the head, lumbar spine, chest, and abdomen.
