Technique for dynamically adapting an exposure value in interactive rendering

A computing device for dynamically adapting an exposure value for consistent interactive rendering of a volumetric medical dataset, the computing device comprising:

• a first receiver configured to receive a volumetric medical dataset;
• a processor configured to provide a rendering set comprising a plurality of rendering types, wherein each rendering type within the rendering set is adapted for providing an image dataset derived from the received volumetric medical dataset, wherein the plurality of rendering types comprises at least two different rendering types;
• a graphics processing unit configured to output, to a display device, an image dataset pertaining to the received volumetric medical dataset according to a first rendering type within the rendering set, wherein the outputting comprises applying a first exposure value to the image dataset;
• wherein the processor is further configured to determine a second exposure value for a second rendering type within the rendering set, wherein the second exposure value is adapted for displaying the image dataset according to the rendering type on a display device, and wherein the second exposure value for the second rendering type is determined based on the first exposure value according to the first rendering type, wherein the determining of the second exposure value for the second rendering type is based on a consistency requirement for changing rendering types of the image dataset output;
• a second receiver configured to receive a user input for modifying the output of the image dataset;
• wherein the processor is further configured to select, based on the received user input, the second rendering type with the determined second exposure value for outputting the image dataset pertaining to the received volumetric medical dataset, wherein the second rendering type differs from the first rendering type;
• wherein the graphics processing unit is further configured for outputting, to the display device, the image dataset according to the selected second rendering type with the determined second exposure value.

A non-transitory computer readable storage medium having stored thereon a computer program, that when executed by a computer, performs:

• receipt of a volumetric medical dataset;
• provision of a rendering set comprising a plurality of rendering types, wherein each rendering type within the rendering set is adapted for providing an image dataset derived from the received volumetric medical dataset, wherein the plurality of rendering types comprises at least two different rendering types;
• output, to a display device, of an image dataset pertaining to the received volumetric medical dataset according to a first rendering type within the rendering set, wherein the outputting comprises applying a first exposure value to the image dataset;
• determination of a second exposure value for each rendering type within the rendering set, wherein the exposure value is adapted for displaying the image dataset according to the rendering type on the display device, and wherein the second exposure value for each rendering type is determined based on the first exposure value according to the first rendering type, wherein the determining of the exposure value for each rendering type is based on a consistency requirement for changing rendering types of the image dataset output;
• receipt of a user input for modifying the output of the image dataset;
• selection, based on the received user input, of a second rendering type with the determined second exposure value for outputting the image dataset pertaining to the received volumetric medical dataset, wherein the second rendering type differs from the first rendering type;
• and
• output, to the display device, of the image dataset according to the selected second rendering type with the determined second exposure value.
