摘要:
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.

Generating anatomically specific movie driven medical image review is provided. Scan data is received representing an anatomy of a patient. A movie generation preset selection associated with the scan data is received. Anatomical landmarks within the scan data are detected. A movie of the patient is generated based on the scan data, the movie generation preset, and the anatomical landmarks.

A method of visualizing a three-dimensional object from a data volume is disclosed. In an embodiment, the method includes computing an irradiance cache for the data volume; and applying the irradiance cache during rendering of a three-dimensional image from the data volume. In an embodiment, entries of the irradiance cache are organized in a uniform grid.

A method and apparatus for volume rendering based 3D image filtering and real-time cinematic volume rendering is disclosed. A set of 2D projection images of the 3D volume is generated using cinematic volume rendering. A reconstructed 3D volume is generated from the set of 2D projection images using an inverse linear volumetric ray tracing operator. The reconstructed 3D volume inherits noise suppression and structure enhancement from the projection images generated using cinematic rendering, and is thus non-linearly filtered. Real-time volume rendering can be performed on the reconstructed 3D volume using volumetric ray tracing, and each projected image of the reconstructed 3D volume is an approximation of a cinematic rendered image of the original volume.
摘要:
A three-dimensional object is provided within a light probe, at least one intensive light source of the light probe is detected and selected. Furthermore, a multiplicity of rays are simulated for a respective visualization pixel. For a respective ray entering into an object volume, i) a scattering position is determined, ii) a scattering direction is selected, with a decision being made depending on a first random process as to whether the ray is scattered in the direction of the intensive light source or in a scattering direction to be selected depending on a second random process, and iii) the ray is scattered in the selected scattering direction. Steps i) to iii) are repeated until the ray is absorbed in the object volume or emerges from the object volume and impinges on the light probe.

The inner volume of an inhomogeneous three-dimensional object is visualized by a plurality of simulated visual rays. For a respective visual ray entering the object volume, i) a scatter position is determined along the visual ray, ii) a scatter direction is selected in dependence on a random process, and iii) the visual ray is scattered at the scatter position in the selected scatter direction. Steps i) to iii) are repeated until the visual ray is absorbed in the object volume or exits the object volume, wherein the exiting visual ray is incident on an illumination source and, in dependence on a brightness and/or color value of the illumination source, an illumination contribution of the visual ray to a respective visualization pixel is ascertained.
摘要:
An artificial intelligence agent is machine trained and used to provide physically-based rendering settings. By using deep learning and/or other machine training, settings of multiple rendering parameters may be provided for consistent imaging even in physically-based rendering.
摘要:
A first interface for reading image data of an anatomical region obtained by means of a medical imaging method is provided. A modeling module serves for establishing a volumetric biomechanical structure model of the anatomical region on the basis of the image data . Moreover, provision is made of a tracking module, couplable with a camera, for video-based registration of spatial gestures of a user. Furthermore, a simulation module, based on the biomechanical structure model, serves to assign a registered gesture to a simulated mechanical effect on the anatomical region , simulate a mechanical reaction of the anatomical region to the simulated mechanical effect, and modify the biomechanical structure model in accordance with the simulated mechanical reaction. Moreover, provision is made for a visualization module for the volumetric visualization of the biomechanical structure model.
