Abstract: An apparatus and method are provided for computed tomography (CT) imaging to reduce artifacts due to objects outside the field of view (FOV) of a reconstructed image. The artifacts are suppressed by using an iterative reconstruction method to minimize a cost function that includes a de-emphasis operator. The de-emphasis operator operates in the data domain, and minimizes the contributions of data inconsistencies arising from attenuation due to objects outside the FOV. This can be achieved by penalizing images that manifest indicia of artifacts due to outside objects especially those outside objects have high-attenuation densities and minimizing components of the data inconsistency likely attributable to the outside object.

Abstract: A method and apparatus is provided to generate a multiresolution image having at least two regions with different pixel pitches. The multiresolution image is reconstructed using projection data having various pixel pitches corresponding to the pixel pitches of the multiresolution image. By using a higher resolution inside regions of interest (ROIs) in both the image and projection domains and lower resolution outside the ROIs, fast image reconstruction can be performed while avoiding truncation artifacts, which result imaging is limited to an ROI excluding attenuation regions. Further, those regions of greater clinical relevance and greater structural variance within the reconstructed images can be selected to be within the ROIs to improve the clinical benefit of the multiresolution image. The multiresolution image can be reconstructed using an iterative reconstruction method in which the high- and low-resolution regions are uniquely evaluated.

Abstract: Technologies are provided in embodiments to monitor and analyze networks. The embodiments can cause a bit in a first bit sequence of a device filter to indicate a failure state based on not receiving a message from a node in a network during a reporting time interval, and upon the reporting time interval expiring, to combine the first bit sequence with a corresponding bit sequence of a shadow filter. The combination preserves, in the shadow filter, an indication of the failure state from the bit in the first bit sequence and any other indications of failure states from bits of the corresponding bit sequence of the shadow filter. More specific embodiments cause, upon the reporting interval expiring, a bit in a second bit sequence of the device filter to indicate a no failure state based on an indication of another no failure state in the first bit sequence.
