摘要： A system (20) an image acquisition device, an image workstation, computer-readable medium and method for visualizing an anatomical tree structure is disclosed. The anatomical tree structure is segmented from a three-dimensional image set of at least a portion of a body. A planar angular visualization of the anatomical tree structure is then determined. The planar angular visualization of the anatomical tree structure is then displayed. Since the displayed anatomical tree structure has no occlusions or intersections of segments, the anatomical tree is much easier to read which facilitates subsequent automated or manual diagnosis of the tree for anomalies.

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.
摘要翻译：公开了一种计算机程序产品，分割算法，显示图像产品，工作站和PACS系统，所有这些都允许在失败的分割算法中关闭孔或间隙。这是通过识别未包括在由分割算法识别的数据点的集合中的至少一个数据点来实现的，并且导出围绕该数据点的径向方向的百分比的度量，其与分割中的至少一个检测到的数据点相交，进一步只有当径向方向的计算百分比高于预定阈值时，才将新识别的数据点包括进分割。以前仅通过修改分割算法的步骤或形态学重建来解决分段病变中的孔和间隙的问题，后一种方法需要使用不适合大孔的结构元素。

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： Coronary artery segmentation is a crucial task in cardiac CT image processing. This is often a tedious task performed manually by an operator. According to the present invention, a method is provided which combines data from multiple cardiac phases during the segmentation process in order to deliver a complete and continuous coronary vessel tree. Advantageously, this may allow for an improved visualization and segmentation of vessels, for example, in coronary CTA.
