Higher order detector z-slope correction for a multislice computed tomography system
Реферат: A system for producing a tomographic image of an object from projection data, comprising: an x-ray source (14) emitting x-rays; a detector (18) having a plurality of detector cells, said detector receiving said x-rays and providing said projection data as an output, said projection data representing the attenuation of said x-rays; and an image processor that applies a correction factor to an error factor extracted from said projection data to correct for image artifacts resulting from non-uniformity among said projection data, said correction factor having a computational complexity that remains substantially the same regardless of the complexity of said non-uniform projection data. 3273 ה' בכסלו התשס" ג - November 10, 2002
