A computer-implemented method for rendering medical volume data including first volume data is described. The method comprises: performing a first volume rendering process on the first volume data to generate a first volume rendering of the first volume data. The first volume rendering process includes determining first depths of respective locations of the first volume rendering and storing the depths in association with the respective locations. The method also comprises performing a further process, including a second volume rendering process, on the medical volume data, to generate a second volume rendering, using the determined first depths and respective locations.

Computer-implemented method for rendering medical volume data

A computer-implemented method is for visualization of a three-dimensional object represented by volume data for a user in the form of a two-dimensional visualization image including a plurality of visualization pixels. In an embodiment, the method includes: providing an image synthesis algorithm designed for visualization of the three-dimensional object by mapping the volume data onto the visualization pixels; detecting an instantaneous viewing direction of the user; determining a focus area defined as a region of the visualization image, upon which the user focuses based upon the instantaneous viewing direction; adjusting the image synthesis algorithm such that the computing effort required for the mapping for visualization pixels outside of the focus area is lower than for visualization pixels inside of the focus area; and mapping volume data onto the visualization pixels with the adjusted image synthesis algorithm.

Method and device for visualization of three-dimensional objects

The present embodiment relates to a renderer and an interactive method for image editing of medical 3D anatomical data. The method includes receiving a dataset with volumetric image data, which have been acquired from an image acquisition modality, and providing a signed distance field data structure of the received dataset. Further, editing operations are received from a user interface for editing at least a part of the provided signed distance field data structure. A visualization of the editing operations is calculated and displayed on a display.
