Problems solved by technology

[0002] In recent years, with the continuous development of medical surgical methods, minimally invasive surgery and robotic navigation surgery have been gradually applied to brain surgery. Doctors can observe the surgical site through micro-probes, but the viewing angle of micro-probes is limited, and the data collected by micro-probes The image is a two-dimensional (Second Dimension, 2D) image, which cannot provide more visual information for the doctor, and does not use the doctor to accurately diagnose and analyze the lesion

Abstract

The invention provides a brain structure three-dimensional reconstruction method and device and terminal equipment. The method comprises the following steps: acquiring a 2D image of a brain, inputtingthe 2D image of the brain into a trained 3D brain point cloud reconstruction model for processing, and outputting to obtain a 3D point cloud of the brain, wherein the 3D brain point cloud reconstruction model comprises a ResNet encoder and a graph convolutional neural network, the ResNet encoder is used for extracting an encoding feature vector of a 2D image of the brain, and the graph convolutional neural network is used for constructing a 3D point cloud of the brain according to the encoding feature vector. Based on a brain structure three-dimensional reconstruction method provided by the invention, the 2D image of the brain can be converted into the 3D point cloud of the brain, more visual information is provided for doctors, and the doctors can better diagnose and treat.

Description

technical field [0001] The present application belongs to the technical field of artificial intelligence, and in particular relates to a method, device and terminal equipment for three-dimensional reconstruction of brain structure. Background technique [0002] In recent years, with the continuous development of medical surgical methods, minimally invasive surgery and robotic navigation surgery have been gradually applied to brain surgery. Doctors can observe the surgical site through micro-probes, but the viewing angle of micro-probes is limited, and the data collected by micro-probes The image is a two-dimensional (Second Dimension, 2D) image, which cannot provide more visual information for the doctor, and does not use the doctor to accurately diagnose and analyze the lesion. Compared with the flat space of 2D images, three-dimensional (Three Dimensional, 3D) point cloud data contains more spatial structure information, which can provide doctors with more visual informati...
