Abstract

The invention discloses a personalized mitral valve automatic modeling method. The method comprises the following steps: constructing a mitral valve three-dimensional ultrasonic image database; inputting data in the mitral valve three-dimensional ultrasonic image database into a convolutional neural network as a training data set to obtain a trained mitral valve automatic segmentation model; acquiring a three-dimensional ultrasonic image of a target mitral valve, inputting the target ultrasonic image into the mitral valve automatic segmentation model, and outputting a target segmentation result; obtaining point cloud data through the target segmentation result; performing curved surface fitting according to the point cloud data to obtain a curved surface equation of the mitral valve, and obtaining a three-dimensional curved surface model of the mitral valve through the curved surface equation of the mitral valve. The invention also discloses a corresponding system and equipment. According to the method, automation of personalized mitral valve modeling is realized, and the modeling time is greatly shortened. The curved surface model obtained through automatic modeling can be subjected to three-dimensional zooming rotation checking, and can also be used for measuring the spatial position relation between mitral valve tissue structures.
