摘要： A computer program product, segmentation algorithm, display image product, workstation and PACS system are disclosed, all allowing the closing of holes, or gaps, in failed segmentation algorithms. This is achieved by identifying at least one data point not included in the collection of data points identified by the segmentation algorithm and deriving a measure of the percentage of radial directions around that data point which intersect at least one detected data point in the segmentation, further including the newly identified data point into the segmentation only if the calculated percentage of radial directions is above a pre-determined threshold. The problem of holes and gaps in segmented lesions was previously only solved by amending the steps of the segmentation algorithm or by morphological reconstruction, which latter method requires use of structuring elements themselves not suitable for large holes.

摘要： A system (500) for visualizing a vascular structure represented by a three- dimensional angiography dataset is disclosed. Respective voxel values are associated with respective voxels. The dataset represents a vascular structure. The system comprises means (502) for establishing respective filling values; means (504) for identifying respective minimum filling values; means (506) for computing respective deficiency values; and an output (514) for providing a visualization in dependence on the deficiency values. A respective filling value is indicative of an amount of blood flow at the respective position in the vascular structure. A respective minimum filling value is a minimum of the filling values associated with the positions upstream of the respective position. A respective deficiency value is indicative of a difference between the filling value associated with the respective position and the minimum filling value associated with the respective position.

摘要： A computer program to identify a single seed point in an image is presented in which a manually positionable region of interest is presented to the user in the image and a single seed point is selected according to pre-defined criteria from the pixels delineated by the region of interest. Such seed points are used to initialise, for example, segmentation algorithms. The invention improves accuracy of seed point selection and also increases reproducibility. In an advantageous embodiment the region of interest is also sizable and a workstation and computer mouse with rotatable control device are provided, where the rotatable control device is used to control the size of the region of interest.

摘要： When adjusting parameters of a segmentation protocol for segmenting a volume of interest in an anatomical image, a user selects a superparameter (50) that includes multiple internal parameters (52) for adjusting a raw segmentation of the volume interest. As a weight of the selected superparameter is adjusted, weights of the internal parameters associated with the superparameter are adjusted according to a superparameter segmentation adjustment algorithm (20). The volume of interest is iteratively re- segmented after each internal parameter adjustment, transparently to the user, until a predetermined amount of change has been effected in the volume of interest segmentation, at which time the re-segmented volume of interest is displayed to the user.

摘要： A method includes registering a first sub-portion of a first image with a corresponding second sub-portion of a second image, and registering the second sub- portion of the second image with a corresponding third sub-portion of the first image. The first sub-portion encompasses a first object of interest, and the third sub-portion encompasses a third object of interest. The method further includes reducing a size of the first sub-portion when the first and third objects of interest are substantially similar. The method further includes repeating the steps of registering the first sub-portion, registering the second sub-portion, and reducing the size of the first sub-portion until the first and third objects are not substantially similar.
