摘要： A method and system for the computerized registration of radionuclide images with radiographic images, including generating image data from radiographic and radionuclide images of the thorax. Techniques include contouring the lung regions in each type of chest image, scaling and registration of the contours based on location of lung apices, and superimposition after appropriate shifting of the images. Specific applications are given for the automated registration of radionuclide lungs scans with chest radiographs. The method in the example given yields a system that spatially registers and correlates digitized chest radiographs with V/Q scans in order to correlate V/Q functional information with the greater structural detail of chest radiographs. Final output could be the computer-determined contours from each type of image superimposed on any of the original images, or superimposition of the radionuclide image data, which contains high activity, onto the radiographic chest image.

摘要： The present invention provides a system for performing fast segmentation and image processing for enhanced three dimensional (3-D) visualization of a subject. The present invention automatically extracts unwanted dominant features from images while preserving the desired information. The present invention works especially well with Computed Tomography Angiograms (CTA) for viewing vasculature of a subject's head. Segmenting and removing dominant structures from image data permits visualization techniques such as maximum intensity projection (MIP), surface rendering and volume rendering, to provide enhanced vessel visualization.

摘要： Digital image processing method for local determination of the center and the width of objects in the form of contrasting bands on a background. A digital image processing method, for representation of objects in the form of contrasting bands of substantially uniform intensity on a substantially uniform background, includes a step for the identification of pixels situated on the central lines of the objects, which step is referred to as a "tracking" step. This method is characterized in that the step includes a first filtering operation which is executed by applying, to each image, a series of N lozenge-type-bidimensional, selective, recursive low-pass filters having respective ones of the principal directions angulary spaced apart 180.degree./N in order to determine the direction of each band-shaped object segment as that in which the response of one of the filters is maximum.

摘要： A digital radiographic image is segmented into various regions and a region thereof is further decomposed into subregions, wherein digital image data is acquired and subjected to multiple phases of digital imaging processes. The region decomposition method first uses progressively smoothing techniques to generate smoothed regions at multiple scales. Next, the number of connected components at each scale is computed for each smoothed region. A shape spectrum, which is the number of connected components as a function of scale, is subsequently constructed to determine the most stable range of scales and the most stable number of subregions into which the region is decomposed. Each pixel is then classified into subregions, according to the geometrical relationship of the connected components detected at most stable scales. Finally, a decomposed map is generated to function as multivalued templates for any further image processing to be done on various decomposed subregions.

摘要： In the image processing apparatus, the control unit generates a plurality of divided regions by dividing the image in accordance with similarity calculated based on pixel values and pixel locations, and identifies a selection range constituted by one or more of the plurality of divided regions in accordance with the selection operation received by the input unit. The control unit performs erosion processing with respect to the selection range by reducing a number of pixels constituting the selection range, and performs dilation processing with respect to the selection range resulting from the erosion processing by increasing the number of pixels constituting the selection range resulting from the erosion processing. The number of pixels constituting the selection range resulting from the dilation processing is greater than the number of pixels constituting the selection range before the erosion processing.

摘要： A system and method for extracting image information from a video frame for regions of a the video frame that likely are objects of interest in a scene. An initial region set is generated by comparing luminance image information and color image information of a video frame with luminance image information and color image information of a background image for the scene. A high confidence region set is generated comprising regions from the initial based upon edge information of the regions and edge information in the background image. A final region set is generated by combining one or more regions in the high confidence region set if such combinations satisfy predetermined criteria, including size, region proximity and morphological region dilation.

摘要： An automatic computer implemented technique which may be used for identifying markers and determining the centroids of fiducial markers (e.g., cylindrical fiducial markers) attached to the head in magnetic resonance (MR) and X-ray computed tomography (CT) volume images is disclosed. This technique may be referred to as image space localization. A first portion of the technique identifies many candidate voxel points included in a bright area of the image which may correspond to candidate markers. A second portion of the technique selects from the identified candidate voxels a predetermined number of candidate points of the image volume that are most likely to lie within an actual fiducial marker. The centroid for each of these markers is then determined. The method finds markers whose images are of a higher intensity than their surroundings and which have a given shape and size.

摘要： A method of processing digital angiographic images which enables automatic detection of stenoses includes a tracking step for the identification of pixels or points situated on the central lines of vessels, and a step for the detection of stenoses by measurement of the intensity of pixels along the central lines of the vessels. The stenoses detection step includes a sub-step for deciding whether a pixel zone is a potential stenosis zone when the intensity of its pixels exhibits a local variation so as to assume an intermediate value between the intensity of the pixels to both sides of this zone and the intensity of the pixels of the image background, a sub-step for defining an icon around potential stenosis zones, and a sub-step for the extraction of the pixels of edges of the vessel segments in the icons.
