    摘要: A system and method are provided for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system that allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ; where imaging data sets are acquired using conventional two-dimensional scans of the object in both a supine and prone orientation, and correspondence between the respective data sets is determined to permit jumping from one visualization orientation to the other while remaining at the same virtual location within the organ.

    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.

    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: A computer based system and method of visualizing a region using multiple image data sets is provided. The method includes acquiring first volumetric image data of a region and acquiring at least second volumetric image data of the region. The first image data is generally selected such that the structural features of the region are readily visualized. At least one control point is determined in the region using an identifiable structural characteristic discernable in the first volumetric image data. The at least one control point is also located in the at least second image data of the region such that the first image data and the at least second image data can be registered to one another using the at least one control point. Once the image data sets are registered, the registered first image data and at least second image data can be fused into a common display data set. The multiple image data sets have different and complimentary information to differentiate the structures and the functions in the region such that image segmentation algorithms and user interactive editing tools can be applied to obtain 3d spatial relations of the components in the region. Methods to correct spatial inhomogeneity in MR image data is also provided.

    摘要: Method of converting continuous 3-D geometrical representations into a discrete set of voxels in discrete 3-D voxel space. In one embodiment, a method is provided for converting a continuous 3-D straight line segment into a discrete set of voxels connected together in discrete 3-D voxel space. In another embodiment, a method is provided for converting a continuous 3-D parametric polynomial curve segment into a discrete set of voxels connected together in discrete 3-D voxel space. In an alternative embodiment, a method is provided for converting a continuous 3-D parametric polynomial surface patch into a discrete set of voxels connected together in discrete 3-D voxel space. Yet in another embodiment of the present invention, a method is provided for converting a continuous 3-D parametric polynomial volume element into a discrete set of voxels connected together in discrete 3-D voxel space. The method of the present invention is incremental in nature and uses all integer arithmetic. The method of the present invention is also characterized by symmetrical decisional process loops using substantially the same decisional process logic in each of the x, y and z coordinate directions, and thus is capable of generating discrete sets of voxels having a variety of connectivities.
