Patent number: 8049752Abstract: A system and method of determining a sampling rate for rendering a volumetric image, the method includes determining a regional variation value representing regional data, color, and/or alpha variation. An accumulated opacity value is determined that represents opacity accumulated over a ray in the image, and a regional opacity value is determined that represents regional opacity. A quality setting is accessed that represents a default image quality, and the sampling rate is adjusted as a function of the regional variation value, the accumulated opacity value, the regional opacity value, and the quality setting. The regional variation value may be determined by iteratively generating a maximum regional variation table during pre-processing, quantizing the maximum regional variation table where the transfer function is defined based on a histogram of the volumetric image, and computing the regional variation value using the maximum regional variation table.Type: GrantFiled: April 18, 2007Date of Patent: November 1, 2011Assignee: Siemens Medical Solutions USA, Inc.Inventors: Lining Yang, Udeepta D.

Patent number: 7903113Abstract: A system and method for rendering an MIP image that has reduced high frequency component loss and reduced chessboard artifacts. The method includes accessing volumetric data, having random noise. Rays are shot, or cast, through the volumetric data, onto a voxel grid, which has grid points. Sampling data along each ray is performed to obtain selected sample data points on the ray and a distance from a selected point to a nearest grid point is determined. A voxel intensity value is accessed at each selected point, as a function of the position of the selected point relative to the nearest grid point. The difference between the voxel intensity at each selected point is minimized an image is rendered from the volumetric data as a function of the minimizing step. Multiple methods may be used to minimize the difference between the voxel intensity at each selected point. These include for example 1.) applying a localized low pass filter, 2.) applying a localized high order interpolation kernel, and 3.Type: GrantFiled: June 29, 2007Date of Patent: March 8, 2011Assignees: Siemens Medical Solutions USA, Inc., Siemens AktiengesellschaftInventors: Smita Krishnan, Robert Schneider, Lining Yang, Min Xie

Patent number: 7839404Abstract: A method and system of increasing the speed of a ray-casting algorithm for producing direct volume rendering images in the melt-through interaction mode. Since the viewing direction is not changed during a melt-through interaction, it is possible to reuse the samples calculated along each ray from one frame to another. The samples along each ray are partitioned into different groups, and the samples within each partition can be composited to generate an RGBA-tuple (Red Green Blue and Alpha, which is an opacity factor) for the partition. The associative property of the composition operation allows computation of the final RGBA value for each ray by compositing the RGBA-values of the partitions, instead of compositing the RGBA-values of each sample along the ray.Type: GrantFiled: June 27, 2007Date of Patent: November 23, 2010Assignee: Siemens Medical Solutions USA, Inc.Inventors: Udeepta D.

Patent number: 7675517Abstract: A system and method for rendering an image that includes accessing image data and dividing the image data into one or more blocks. One or more corner points of the blocks are identified and rays are cast through voxel space of the image data in the direction of the corner points to determine one or more integrated values for the corner points. The integrated values are then sampled and compared to the sampled values for each combination of the corner points. A difference value (diffvalue) is calculated as a function of the comparison and an initial gradient (grad) is calculated as a function of a Reduced Path Octree (RPO) structure during the casting of rays. Next, a maximum gradient (maxGrad) is calculated based on the initial gradient (grad). Finally, an image processing operation is determined as a function of the maximum gradient (maxGrad) and the difference value (diffvalue).Type: GrantFiled: February 21, 2007Date of Patent: March 9, 2010Assignee: Siemens Medical Solutions USA, Inc.Inventors: Lining Yang, Daqing Xue
