摘要： A method for selecting and/or labeling a vessel image includes operating an imaging system to obtain reconstructed image data including a volume having vessels therein. A bone removal routine is then applied to the reconstructed image data to produce a bone-free image. An initial point on a main vessel in the bone-free image is located, and bifurcation points and branches departing from the main vessel are identified. An adjacency graph of each branch coming from the main vessel is built. The method includes either or both of selecting and displaying a best or at least a favorable path through the vessels in accordance with predetermined criteria using the adjacency branch, or labeling and displaying branches of the main vessel.

摘要： An automatic segmentation of the left or right cavities of the heart muscle is carried out. Once it is decided which cavities have to be isolated, three steps are implemented. A first step is performed to determine which is the volume comprising the cardiac cavities in a volume image resulting from an examination. This first step comprises a thresholding operation and an erosion, and then the determining of the greatest connected component. In a second step, an identification) is made of the left and right cavities. In a third step, a precise reconstruction is made of the contours of the left or right cavities for which it is sought to make the segmentation. The reconstruction is done by the watershed algorithm.
