A nonuniform detector aperture for CT.

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 in a CT image with a minimum cost in dose efficiency by varying the sensitivity of...

Spectral detector CT for cardiovascular applications.

Spectral detector computed tomography (SDCT) is a novel technology that uses two layers of detectors to simultaneously collect low and high energy data. Spectral data is used to generate conventional polyenergetic images as well as dedicated spectral images including virtual monoenergetic and material composition (iodine-only, virtual unenhanced, effective atomic number) images. This paper prov...
