    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: An automated method (1) for the automatic extraction of a pulmonary vessel tree from a 3D medical image, such as multi-slice CT data, is disclosed. A segmented pulmonary vessel is identified as either an artery or a vein by determining a measure for arterialness for the vessel. The measure is based on a relation of the orientation of a local bronchus to the orientation of the segmented pulmonary vessel of the local bronchus. When a vessel is identified as a pulmonary artery, it is added to the pulmonary artery tree. Radii of the pulmonary artery and bronchus are measured automatically and positions where a ratio of these radii exhibits unusual values are presented in a display, preferably for suggesting further assessment by a radiologist, which for instance is useful for pulmonary embolism detection.

    摘要: A string of computer instructions is presented to output medical image data containing voxels representative of contrast enhanced material, and arranged to operate on a first object data set comprising voxels depicting contrast enhancement, whereby it segments a sub-set of voxels in the first object data set which voxels describe contrast enhanced vessels, and uses the results of the segmentation to partition the voxels depicting contrast enhancement into a first group of voxels describing the segmented vessels and a second group of voxels describing the remaining contrast enhanced voxels, and uses the partition to output a second object data set comprising voxels depicting contrast enhancement in which the difference between the voxels of the first group and the voxels of the second group is identifiable. It is particularly advantageously applied to dynamic contrast enhanced breast imaging.
