1. A computer-implemented method for navigation and display of 3D image data, comprising:
retrieving a 3D image dataset to be displayed;
receiving identification of a highlight position within the 3D image dataset;
calculating a scalar opacity map for the 3D image dataset, the scalar opacity map having a value for each of a plurality of positions in the 3D image dataset, the respective value being dependent on a respective distance from the highlight position, and on the value of the 3D image at the respective position relative to the value of the 3D image at the highlight position; and
applying the opacity to the 3D image dataset to generate a modified 3D image view.
