Segmentation method and device, computer equipment and storage medium

Abstract

The invention relates to a segmentation method and device, computer equipment and a storage medium. The outer boundary points of a target area are determined; a lower boundary line of the target areaand a reference seed point of the target area are determined according to the outer boundary point of the target area The computer equipment is executed according to the lower boundary line of the target area and the reference seed point of the target area; namely, the computer equipment automatically determines the segmentation from the determination of the outer boundary point of the target areato the segmentation of the target area; thus, each step in the process of segmenting the nasal cavity and paranasal sinus through the method is automatically carried out, the accuracy of the segmentation result of the nasal cavity and paranasal sinus is greatly improved, manual interference is not needed in the segmentation process, the segmentation time is greatly saved, and the high efficiencyand accuracy of the segmentation process are guaranteed.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a segmentation method, device, computer equipment and storage medium. Background technique [0002] The nasal cavity is an important part of the upper respiratory tract and an important channel for gas exchange between the lungs and the outside world. The paranasal sinuses connected to it are distributed around the nasal cavity. The construction of a three-dimensional model of the nasal cavity and paranasal sinuses is useful for studying the anatomical structure and lesions of the nasal cavity and conducting nasal It is of great significance in internal surgery, planning of transnasal surgery path and computer-assisted therapy. [0003] Usually, before constructing a three-dimensional model of the nasal cavity and paranasal sinuses, the nasal cavity and paranasal sinuses must be accurately segmented. In the prior art, most of the segmentation algorithms for the nasal ...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to provide a segmentation method, device, computer equipment and storage medium for the above-mentioned existing technical problems that the segmentation process of the nasal cavity and paranasal sinuses is more complicated, time-consuming, and less accurate.
