CORONARY ARTERY CALCIFIED PLAQUE DETECTION METHOD AND APPARATUS

摘要

The present disclosure relates to a coronary artery calcified plaque detection method and apparatus. The method comprises: segmenting an image to be processed, and determining a plurality of target regions of a first organ in said image; for any target region, determining a first grayscale threshold value and a second grayscale threshold value of the target region according to grayscale information of the target region; respectively determining a suspected lesion region and a pseudo lesion region in the target region according to the first grayscale threshold value and the second grayscale threshold value of the target region; and determining a lesion region of the first organ according to the suspected lesion regions and pseudo lesion regions of the target regions. According to the embodiments of the present disclosure, not only can the omission of calcified plaque at small branch blood vessels of a coronary artery blood vessel in an image to be processed be effectively reduced, but the recall rate of calcified plaque is also improved, and the accuracy of the identification of calcified plaque can be significantly improved.
