Abstract: 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.

Abstract: The invention relates to visualization of medical images, and in embodiments to the visualization of the left ventricle of the human heart or other organs. A method of visualizing one or more sets of voxel data is disclosed. The method comprising: providing one or more sets of voxel data, providing and segmenting the voxel data in accordance with a segment model. The segmented voxel data is reformatted to fit a reference shape (20) being defined by at least an inner (22) reference surface and an outer (23) reference surface. The reformatted voxel data is mapped to a target shape being defined by at least a first (29) target surface and a second (200) target surface. The target shape is moreover visualized. The mapping of the reformatted voxel data to a target shape is a mapping of one or more property values from the inner reference surface to the first target surface, and from the outer reference surface to the second target surface, and where a direction (26, 27) extending along the inter- surface distance of the reference shape is maintained in the target shape.

Abstract: The invention relates to a system (100) for determining a feedback on a three- dimensional location of a pointer in a three-dimensional region of image data, the system comprising: a display unit (110) for computing a view of the three-dimensional region for displaying on a display; a pointer unit (115) for computing a two-dimensional location of the pointer on the view of the three-dimensional region, based on a pointer location input; a location unit (120) for computing a three-dimensional location in the three-dimensional region, based on a two-dimensional location on the view of the three-dimensional region; and a shadow unit (125) for determining a set of two-dimensional locations for displaying a shadow on the view of the three-dimensional region, wherein the set of two-dimensional locations for displaying the shadow comprises the two-dimensional location of the pointer on the view of the three-dimensional region, and wherein a set of three-dimensional locations, computed based on the set of two-dimensional locations for displaying the shadow, is connected. Typically, the connected set of candidate three-dimensional locations comprising the three-dimensional location of the pointer is comprised in a structure indicated by the pointer. Therefore, the determined feedback on a three-dimensional pointer location on a view of the three-dimensional region of the image data improves clarity and decreases ambiguity of indicating a 3D location on the structure.
