METHOD AND APPARTUS OF MACHING MEDICAL IMAGES

摘要

A method for matching a plurality of medical images is disclosed. The medical image matching method according to an embodiment of the present invention comprises: obtaining a first medical image taken before a medical procedure and a second medical image taken in real-time during the medical procedure; extracting feature points for each of at least two adjacent entities, which are identifiable in the second medical image having a low resolution, from the first medical image and the second medical image among a plurality of anatomical entities adjacent to an organ of interest of a patient; and matching the first medical image and the second medical image based on a geometrical relationship between the adjacent objects displayed by the feature points of the first medical image and a geometrical relationship between the adjacent objects displayed by the feature points of the second medical image.
