Abstract
Medical imaging modalities generate increasingly more and very large three-dimensional data sets. According to an exemplary embodiment of the present invention, a three-dimensional data set of an object of interest is interactively visualized with a varying sampling rate in an image. Advantageously, a focus area may be moved by a user interactively during rendering, wherein the sampling rate of a particular part of the image is defined by its relative position to the focus area. Advantageously, this may allow for an improvement of an overall rendering performance.
Claims14
A method of interactively visualizing a three-dimensional data set of an object of interest, wherein the method allows for an interactive input, the method comprising the step of:
- varying a rendering method in an image during the interactive input;
- wherein the variation of the rendering method causes a non-uniform quality of the image;
- and wherein the image is determined on the basis of the three-dimensional data set.
A data processing device, comprising:
- a memory for storing a three-dimensional data set of an object of interest;
- a data processor for performing an interactive visualization of the three-dimensional data set, wherein the interactive visualization allows for an interactive input, wherein the data processor is adapted for performing the following operation:
- loading the three-dimensional data set;
- varying a rendering method in an image during the interactive input;
- wherein the variation of the rendering method causes a non-uniform resolution of the image;
- and wherein the image is determined on the basis of the three-dimensional data set.
A scanner system, comprising:
- a memory for storing a three-dimensional data set of an object of interest;
- a data processor for performing an interactive visualization of the three-dimensional data set, wherein the interactive visualization allows for an interactive input, wherein the data processor is adapted for performing the following operation:
- loading the three-dimensional data set;
- varying a rendering method in an image during the interactive input;
- wherein the variation of the rendering method causes a non-uniform quality of the image;
- and wherein the image is determined on the basis of the three-dimensional data set.
A computer program product for performing an interactive visualization of a three-dimensional data set of an object of interest, wherein the interactive visualization allows for an interactive input, wherein the computer program product causes a data processor to perform the following operation when the computer program is executed on the data processor:
- loading the three-dimensional data set;
- varying a rendering method in an image during the interactive input;
- wherein the variation of the rendering method causes a non-uniform quality of the image;
- and wherein the image is determined on the basis of the three-dimensional data set.
