摘要： Method and apparatus for locally enhancing image data represented as pixels having CT numbers is provided. The image data includes bony structures, and the method comprises segmenting pixels within the image data into areas based on the pixel's CT number. A first area represents a combination of soft tissue and lower density bones and a second area represents higher density bones. A subset of pixels is identified within the first area representative of the lower density bones. An enhancement is applied to the subset of pixels within the first area and to the second area to create an enhanced dataset, and a locally enhanced image is generated based on the image data and the enhanced dataset.

摘要： A method for generating a simulated patient image is disclosed. In an exemplary embodiment, the method includes obtaining image data from an actual patient image and generating simulated noise data. The image data is then combined with the simulated noise data to create the simulated patient image. In one aspect, scan data from the actual patient image is combined with the generated simulated noise data to create pre-image data, and the pre-image data is then reconstructed to create simulated image data. In another aspect, a set of individual noise pattern images for each a plurality of phantom objects is created. At least one of the individual noise pattern images is selected for combination with the actual patient image. The at least one selected individual noise pattern image is then combined with the actual patient image, thereby creating the simulated patient image.

摘要： A method for reducing slice thickness of a computed tomography imaging system including a source configured to direct an x-ray beam through an object toward a plurality of rows of detector elements configured to collect projection data in slices. The method includes steps of obtaining imaging data from a pair of adjacent rows, each of the adjacent rows having an outer edge; deconvolving at least a portion of the imaging data obtained from an area bounded by the adjacent row outer edges; and combining the deconvolved imaging data to obtain a slice sensitivity profile for the adjacent row pair. This method allows a multi-slice imaging system user to implement imaging data deconvolution to reduce slice thickness to less than one millimeter. Thus image resolution is improved without having to modify hardware in existing multi-slice imaging systems.

摘要： The present invention is directed to a method and system of blending data acquired from neighboring partial-scans. Data is acquired from an imaging volume in a series of fractional or partial-scans. Each partial-scan samples a fraction of the imaging volume. During reconstruction, data from the partial-scans are combined to compensate for the unsampled portion of the imaging volume that is experienced in any partial-scan alone.
