Abstract: A data processing technique is provided. In one embodiment, a computer-implemented method includes receiving a set of dynamic computed tomography image data from a computed tomography imaging system, registering the image data, applying a smoothing filter to at least a selection of the registered image data, and outputting the results. The smoothing filter may be, for example, a uniform filter, a triangular filter, a Gaussian filter, a median filter, a percentile filter, a Kuwahara filter, an anisotropic filter, or any combination thereof. Additional methods, systems, and devices are also disclosed.

Abstract: Certain embodiments of the present invention provide systems, methods and computer instructions for detecting a pathological condition of a vasculature. Certain embodiments provide a method for detecting a pathological condition of a vasculature. The method includes accessing imaging data indicative of the vasculature and having a data type, selecting a detection process corresponding to the data type from among a plurality of detection processes, each of the detection processes processing data of a different data type. The method also includes processing the imaging data having the data type with the selected detection process, and superimposing the processed imaging data on the imaging data indicative of the pathological condition of the vasculature.

Abstract: A CT system includes a scintillator array having a first length in an axial direction of the CT system, the scintillator array includes a plurality of scintillator cells along the first length. The CT system includes a controller configured to repeatedly position a subject fore and aft along the axial direction and over a second length of the CT system, the second length greater than the first length, energize an x-ray source to emit x-rays toward the subject while the subject is being repeatedly positioned, and obtain non-uniform projection data of the subject from the scintillator array, the non-uniform projection data comprising the x-rays received from the x-ray source while the subject is repeatedly positioned.
