摘要： A method for curved planar reformation of an image includes receiving a data volume including a medial axis tree of a vessel tree, determining a global rotation axis of the medial axis tree, and casting a line segment from a vessel tree root of the medial axis tree into a predefined direction perpendicular to the global rotation axis. The method includes projecting the medial axis tree onto a reference plane along the line segment. The method further includes re-sampling, from at least one medial axis point of a reference plane, the data volume using a vector perpendicular to a medial axis tangent of the reference plane, wherein the vector defines a sampling direction. The method includes rendering an image of the vessel tree along the vector.

摘要： A method for segmenting coronary vessels in digitized cardiac images includes providing a digitized cardiac image, providing a seed point in the image, selecting a volume-of-interest about the seed point, performing a local segmentation in the volume-of-interest, including initializing a connected component with the seed point and a threshold intensity value to the intensity of the seed point, adding a point to the connected component if the point is adjacent to the connected component and if the intensity of the point is greater than or equal to the threshold value, lowering the threshold intensity value, and computing an attribute value of the connected component, wherein if a discontinuity in the attribute value is detected, the local segmentation is terminated, wherein a local segmentation mask of a vessel is obtained.
摘要翻译：用于在数字化心脏图像中分割冠状动脉血管的方法包括提供数字化的心脏图像，在图像中提供种子点，选择关于种子点的感兴趣体积，在感兴趣的体积中执行局部分割，包括使用种子点初始化连接的分量，并将阈值强度值初始化为种子点的强度，如果该点与所连接的分量相邻，并且如果点的强度大于或等于阈值，降低阈值强度值，以及计算所连接的组件的属性值，其中如果检测到属性值中的不连续性，则终止本地分割，其中获得容器的局部分割掩模。

摘要： A computer-implemented method for pre-processing image data of a three-dimensional volume includes providing the image data of a vessel, applying a super-sampling filter to the image data to generate super-sampled image data having an increased resolution as compared to the image data, applying an unsharp masking filter to the super-sampled image data for increasing contrast of an edge of the vessel, applying a de-noising filer for removing noise surrounding the edge after applying the unsharp masking filter, and storing the image data after applying the de-noising filter thereto.
