摘要： A method and apparatus for displaying arbitrary cross-sectional views of a three-dimensional body from a regular array of values of at least one physical property in the interior of the body includes making physical property measurements with such systems as computerized tomographic x-ray systems, or magnetic resonance imaging systems. Cut planes are defined by the user as displacement from, and rotations from, an arbitrary coordinate origin in the data space. An initial plane of pixel positions of arbitrary density is displaced and rotated to correspond to the cut plane. The values for the physical property at the pixel positions are interpolated from the surrounding measurements of actual values. Cross-sectional images are thereby supplied interactively in real time to support; for example, ongoing surgical procedures.

摘要： A method for processing medical images (240) for use in the detection and diagnosis of disease comprises classifying regions of interest within the medical images based on a hierarchy of anatomical models and signal models of signal information of an image acquisition device (110) used to acquire the medical images. The anatomical models are derived to be representative of anatomical information indicative of a given disease. A computer-aided system for use in the diagnosis and detection of disease comprises an image acquisition device (110) for acquiring a plurality of image data sets and a processor (120) adapted to process the image data sets. The processor (120) is adapted to classify selected tissue types within the image data sets based on a hierarchy of signal and anatomical models and the processor (120) is further adapted to differentiate anatomical context of the classified tissue types for use in the diagnosis and detection of disease.

摘要： An apparatus and method for determining connected substructures within a body is disclosed. The system and method are particularly advantageous for use in medical diagnostic imaging applications. In particular, three dimensional regions exhibiting the same tissue type are similarly labeled. The system and method of the present invention is operable in any situation in which three dimensional signal patterns representing the value of one or more physical properties associated with the substructures within a body at regularly spaced grid locations within the body are presented. A subset of the original data may then be provided to a display processor, particularly one employing gradient normal shading for display of three dimensional images. Even more particularly, the present invention is related to a method and system for determining equivalence classes of of objects, the objects typically comprising one or two dimensional connected regions found in a planar slice of data from magnetic resonance imaging or x-ray tomography systems.

摘要： A graphics workstation displays a polygonal model generated with computer aided design (CAD) software or volumetric data by first converting the the model or volumetric data to a point and normal display list. The "dividing cubes" method is used to convert the polygonal model, while the "marching cubes" method is used to convert the volumetric data. A model clipping circuit determines points which are to be displayed corresponding to the model cut plane desired. A rotate circuit transforms the point and normal display list according to the desired orientation and also converts the normal vectors into levels of shading according to the direction of the normal vector. The voxels in the transformed display list are clipped to a desired screen viewing region by a screen clipping circuit. A depth buffer, compare circuit, and an AND circuit determine voxels which do not lie behind other surfaces, and are proper to display. The AND circuit allows update of the depth buffer and an image memory buffer, the image memory buffer being a screen map. The image memory is displayed on a monitor. The models are manipulated and cut much more rapidly on a low end workstation than would be possible using conventional methods.

摘要： A span processor receives volumetric data from an imaging apparatus and stores the data as a condensed display list in a span memory. After the volumetric data has been stored, the span processor converts the display list to a display list comprised of points and normal vectors which is stored in a point and normal display list memory. A model clipping circuit determines points which are to be displayed corresponding to desired model cut planes. A rotate circuit transforms the point and normal display list according to the desired orientation, and also converts the normal vectors into levels of shading according to the direction of the normal vector. The points in the transformed display list are clipped to a desired screen viewing region by a screen clipping circuit. A depth buffer, compare circuit, and an AND circuit determine voxels which do not lie behind other surfaces, and are proper to display. The AND circuit allows update of the depth buffer and an image memory buffer, the image memory buffer being a screen map. The image memory is displayed on a monitor. The models are manipulated and cut much more rapidly on a low end workstation than would be possible using conventional methods.

摘要： In order to detect and display arbitrary interior surfaces of a three-dimensional body from a regular array of values of at least one physical property in the interior of the body, the physical property measurements are made with systems such as computerized tomographic x-ray imaging, or magnetic resonance imaging. A recursive algorithm starts with a seed voxel in the surface of interest and continues to all adjacent voxels having a common face which is penetrated by the surface of interest. The common surface penetrations are derived from a look-up table which lists the adjacent voxels having a common penetrated face for each voxel index. The voxel index, in turn, is the string of binary digits representing the voxel vertices whose vertex values exceed the surface value of the surface of interest. The resulting list of voxels can be processed by conventional processors to display the surface of interest with greatly reduced interference from nearby, closely intermingled surfaces with the same or similar surface values.
