The invention relates to a system (SYS) for visualizing uncertainty of a contour within a contour uncertainty band in a 2-dimensional (2-D) image, the system comprising: a transfer unit (U30) for applying an uncertainty transfer function, which assigns a renderable property to each location of a plurality of locations within the contour uncertainty band, based on the value of the uncertainty at said location; and a mixing unit (U40) for computing a final image for displaying the 2-D image and the renderable property assigned to each location of the plurality of locations within the contour uncertainty band. The renderable property, e.g., a color, describes the uncertainty of the contour at each location of the plurality of locations within the contour uncertainty band. At each location of the plurality of locations within the contour uncertainty band, the uncertainty may be, for example, the probability that the location is (or, in an alternative embodiment, is not) on the contour. Since the final image comprises, at each location of the plurality of locations within the contour uncertainty band, both the 2-D image value and the renderable property, which can be displayed concurrently or in an alternating manner, the system of the invention is capable of showing the uncertainty of the contour without hiding image details. |
