Abstract

The invention discloses a coronary artery internal and external membrane boundary segmentation method based on adjacent scale complementation. The method comprises the steps of obtaining a to-be-detected IVUS image and inputting the to-be-detected IVUS image to a deep learning network; a cavity convolution module based on multi-scale dense linking extracts image features and establishes a corresponding relation between the IVUS image and the intima and the adventima of the coronary artery; the complementary information learning module based on the adjacent scales obtains complementary information between the scales and determines the sizes and positions of the inner membrane and the outer membrane of the coronary artery; a context supplementing module based on adjacent scales obtains complementary information of contexts, and complements the mutual relation of the intima, the intima and the intima missing in different scales and the vascular structure; and outputting a segmentation result. By using the method, the inner and outer membrane boundaries of the coronary artery can be quickly and accurately segmented. The method can be widely applied to the field of image processing and detection.

Description

technical field [0001] The present invention relates to the field of image processing and detection, in particular to a method for segmenting the border between the inner and outer layers of coronary arteries based on adjacent scale complementarity. Background technique [0002] The identification of the intima and adventitia of coronary vessels is the first step in the clinical quantification of coronary cross-section data. Quantitative vascular indexes are important reference indexes to guide clinical diagnosis. Therefore, it is very important to accurately identify the intima and adventitia of coronary arteries for the diagnosis of patients with coronary artery disease. Clinically, intravascular ultrasound image technology (Intravascularultrasound, IVUS) can clearly show the cross-section and internal structure of coronary arteries, so IVUS images are widely used in clinical detection of coronary intima and adventitia. However, it is time-consuming and inefficient for c...
