| description | The embodiment of the invention relates to the technical field of image or video recognition or understanding, and discloses a method and system for measuring the diameter of an aortic dissection angiography true and false cavity. The method for measuring the diameter of the aortic dissection angiography true and false cavity comprises the following steps: (1) image acquisition: acquiring a CT angiography image set of the aortic dissection position from a system, caching in sequence, and taking the first image as the current image; (2) extracting features; (3) comparing type libraries; (4) finishing inspection; and (5) summarizing. The problems of true and false cavity identification and diameter measurement can be solved through an image geometric feature processing technology, the efficiency is high, the calculation amount is small, and the cost is low. The method can well meet the actual requirements of measuring the diameters of the true and false cavities on the premise that the critical and severe aorti |
