20090016482 | ARTIFACT SUPPRESSION - A computed tomography scanner ( | 01-15-2009 |
20090290774 | DYNAMIC COMPUTED TOMOGRAPHY IMAGING - Projection data ( | 11-26-2009 |
20110096971 | IMAGE RECONSTRUCTION FOR TRUNCATED DETECTOR ARRAY - A reconstruction system reconstructs projection data generated by a detector array of an imaging system having at least one truncated row of detector modules. The reconstruction system includes a projection data generator that augments the projection data with projection data created for the at least one truncated row of detector modules. The reconstruction system further includes a convolver that convolves the augmented projection data. The reconstruction system further includes a back-projector back-projects the augmented projection data and generates volumetric image data indicative thereof. | 04-28-2011 |

20130089252 | METHOD AND SYSTEM FOR NOISE REDUCTION IN LOW DOSE COMPUTED TOMOGRAPHY - A method includes de-noising projection data from a lower dose scan in the projection domain, reconstructing the de-noised projection data to generate volumetric image data, and de-noising the volumetric image data in the image domain. A system includes a projection domain processor ( | 04-11-2013 |
20130202178 | UNDER-SAMPLED, MULTI-ENERGY COMPUTED TOMOGRAPHY (CT) DATA ACQUISITION DATA PROCESSING - A method includes extracting a fully sampled fixed kVp sinogram for a pre-determined kVp of interest from an under-sampled mixed kVp sinogram generated from a switched kVp computed tomography scan. A system includes a fixed sinogram extractor that extracts a fully sampled fixed kVp sinogram from an under-sampled mixed kVp sinogram from a switched kVp computed tomography scan. A method includes de-noising at least one of a fully sampled fixed kVp sinogram extracted from an under-sampled mixed kVp sinogram or the under-sampled mixed kVp sinogram by smoothing lower kVp measurements of the sinograms and sharpening higher kVp measurements of the sinograms. | 08-08-2013 |
20140056503 | MULTI-ENERGY IMAGING - A method includes generating landmarks, for different compositions of materials in scanned structure, wherein a landmark represents a location of a composition of materials, distorted by beam hardening, in a multi-energy Hounsfield Unit space and using the landmarks to perform an image domain material separation and quantification free of beam hardening artifacts. | 02-27-2014 |
