摘要： A temporal image processing system includes a temporal processing controller receiving a first image signal and a second image signal from a scanning unit. The temporal processing controller includes a segmentation module, which isolates at least one region of interest between at least two image signals and generates therefrom a segmentation signal. The temporal processing controller also includes a registration module, which receives the segmentation signal and registers the region of interest and generates therefrom a registration signal. The temporal processing controller still further includes a comparison module, which receives the segmentation signal and the registration signal. The comparison module generates therefrom an adaptive comparison signal of the image signals.

摘要： A temporal image processing system includes a temporal processing controller receiving at least two images temporally spaced apart, from a scanning unit. The temporal processing controller includes a registration module, which registers a region of interest within the images and generates therefrom a registration signal. The temporal processing controller further includes a confidence module receiving the registration signal and generating a confidence map therefrom. The confidence map enhances contrast of temporal changes in the object relative to a contrast due to misregistrations.

摘要： A method and apparatus for analyzing CT images to determine the presence of pulmonary tissue pathology, such as in emphysema, IPF, sarcoid, etc. In accordance with one embodiment, a CT slice is selected to perform an automated, objective, and quantitative analysis of the slice. Initially, an image processing stage is performed, which includes segmentation and edgementation of the selected CT slice for preparation of a series of objective, quantitative measures to be performed on the slice. A region of interest (ROI) is selected on the CT slice in which these objective, quatitative measures are to be taken. The first set of objective, quantitative measures are first order texture measures that describe a frequency of occurrence of all gray levels assigned to pixels within the ROI of the image slice. The second set of objective, quantitative measures are second order texture measures that characterize the spatial interdependencies between particular pixels of the ROI. Fractal analysis could also be performed to provide additional objective, quantitative measures of the ROI. The ROI is classified to a particular tissue pathology class based upon an optimal subset of first or second order texture measures and fractal measures obtained. A color-coded output is displayed for visual presentation to a user indicating the different tissue pathology classes assigned to different regions of the CT slice.

摘要： A portable tomosynthesis imaging system is disclosed that includes a portable X-ray source assembly and a portable detector assembly. The source assembly may be coupled to a portable power supply and controller such that multiple projection X-ray images may be obtained at a site that is not accessible by conventional tomosynthesis imaging systems. Image data may be transmitted from the detector by wired or wireless communication. Tomosynthesis image reconstruction may be performed locally at the portable system or remotely by the transmission of raw or filtered image data from the portable system. The portable system is particularly well-suited to field deployment, such as at accident scenes, scenes of natural or other disasters, or in confined clinical settings.

摘要： Systems, methods and apparatus are provided through which a specialized back-projection process reconstructs a finely detailed and crisp three-dimensional image (3-D) from a series of two-dimensional (2-D) images by pre-filtering the 2-D images with a first group of settings before back-projecting the 2-D images into a 3-D image, and then post-filtering the 3-D image with another group of settings. In some embodiments, the first group of settings and the second group of settings are synergistically optimized in relation to each other to provide emphasis on a structure of interest in the object.
