    摘要： An apparatus and method for real-time volume processing and universal three-dimensional rendering. The apparatus includes a plurality of three-dimensional (3D) memory units; at least one pixel bus for providing global horizontal communication; a plurality of rendering pipelines; at least one geometry bus; and a control unit. The plurality of rendering pipelines each preferably include hardware for interpolation, shading, FIFO buffering, communication and table lookups. The apparatus of the present invention may be coupled to a geometry pipeline for mixing surfaces, images and volumes together in a single image. A method for performing volumetric ray casting of a 3D volume includes the steps of calculating a distance along a major projection axis from a predefined viewpoint; dividing the volume into a plurality of consecutive regions having exponentially increasing bounds; casting a plurality of rays from the viewpoint through the volume; either merging two or more rays or splitting one or more rays at the region boundaries; and repeating the ray casting and merging/splitting steps until the entire volume has been processed. The apparatus and methods of the present invention achieve true real-time performance for high-resolution volume rendering, mixing surfaces and volumes in a single image, and accelerating other imaging operations, including texture mapping and image-based rendering.

    摘要： An apparatus and method for real-time volume processing and universal three-dimensional rendering. The apparatus includes a plurality of three-dimensional (3D) memory units; at least one pixel bus for providing global horizontal communication; a plurality of rendering pipelines; at least one geometry bus; and a control unit. The apparatus includes a block processor having a circular ray integration pipeline for processing voxel data and ray data. Rays are generally processed in image order thus permitting great flexibility (e.g., perspective projection, global illumination). The block processor includes a splatting unit and a scattering unit. A method for casting shadows and performing global illumination in relation to light sources includes sweeping a two dimensional array of rays through the volume can also be implemented with the apparatus. A method for approximating a perspective projection includes using parallel projection.

    摘要： Imaging systems and methods for viewing medical images of human anatomy and, in particular, to a 3-dimensional imaging system that allows a user to efficiently and accurately detect and view coronary artery calcification as displayed graphically on a computer screen. In one aspect, a method for displaying medical images comprises obtaining an image dataset comprising anatomical image data (step 50), automatically grouping connected components in the image data to form groups of connected components (steps 50-57), and displaying the groups of connected components are distinguishable in the displayed image (58-59). The image dataset may comprise a volume data set and the groups of connected components comprise regions of neighboring voxels that share a similar property. The image dataset may comprise a 2-dimensional data set and the groups of connected components comprise regions of neighboring pixels that share a similar property. Different groups of connected components may be displayed in different colors and/or different opacities or certain groups may not be displayed at all.

    摘要： A method of computer aided treatment planning is performed by generating and manipulating a three dimensional (3D) image of a region which includes at least one anatomical structure for which treatment, such as surgery, biopsy, tissue component analysis, prosthesis implantation, radiation, chemotherapy and the like, is contemplated. A virtual intervention, which simulates at least a portion of the contemplated treatment, is performed in the 3D image. The user can then determine the effect of the intervention and interactively modify the intervention for improved treatment results. Preferably, a warning is automatically provided if the intervention poses a risk of detrimental effect. The user can navigate through the contemplated region in the 3D image and assess the results. The treatment plans can be saved for comparison and post treatment evaluation.
