X-ray detector system for computed tomography apparatus, has primary and secondary detector elements whose portions in raster with raster spacings are arranged with respect to respective adjacent detector elements along detector array

摘要

The X-ray detector system has a detector array which is provided with several detector modules, each having several detector elements. The portion of the primary detector elements in a raster with first raster spacing is arranged with respect to respective adjacent detector elements, and portion of secondary detector elements in raster with secondary raster spacing is arranged with respect to respective adjacent detector elements along the detector array.
