Embodiment Construction

[0040] Before introducing the technical solutions provided by the various embodiments of the present application, a brief introduction is made to the proper nouns involved in this article.

[0041] Temporal bone: one of the paired cranial bones in the skull, located on both sides of the skull, bounded between the sphenoid bone, parietal bone and occipital bone, small in size and irregular in shape, with complex internal structure and adjoining relationship, containing positional organs, The auditory organ, facial nerve, vestibulocochlear nerve and internal carotid artery are the most delicate and complex structures in the skull.

[0042] Semicircular canal: It is a part of the bony labyrinth, consisting of three semicircular small tubes perpendicular to each other. as reference figure 2 The schematic diagram of the structure of the semicircular canal structure is shown, the highest position is called the anterior semicircular canal 11 , the latter is called the posterior sem...

Abstract

The invention discloses a temporal bone spatial data processing and positioning method and device and electronic equipment. The processing method comprises the steps of based on a first image containing bilateral outer semicircular canal bone canal structures, determining a reference plane located between the bilateral outer semicircular canal bone canal structures; according to the reference surface, determining symmetrical feature points corresponding to the double-side outer semicircular canal bone canal structures respectively; determining a coordinate origin and a median sagittal plane according to the symmetric feature points corresponding to the bilateral outer semicircular canal bone canal structures; determining a transverse axis surface by utilizing voxel point information corresponding to the double-side outer semicircular canal bone canal structure in the first image; determining a coronal plane according to the transverse axis plane and the median sagittal plane; and establishing a temporal bone space coordinate system based on the coordinate origin, the median sagittal plane, the transverse axis plane and the coronal plane. After a user triggers a calibration requestfor one point in an image, the embodiment provided by the invention can automatically determine and display the coordinate value of the point by utilizing the temporal bone space coordinate system, thereby providing a good basis for subsequent medical research.

Description

[0001] cross reference [0002] This application refers to the Chinese patent application No. 201911337695.1 entitled "Construction method of temporal bone spatial coordinate system, spatial positioning method and electronic equipment" submitted on December 23, 2019, which is fully incorporated by reference into this application. technical field [0003] The present application belongs to the field of computer technology, and in particular relates to a spatial data processing method for temporal bone, a spatial positioning method, a data processing device, a spatial positioning device and electronic equipment. Background technique [0004] The temporal bone is the most delicate and complex bone structure in terms of structure and function in human bones, and it contains important auditory system, blood vessels, arteries and other fine structures. At present, doctors or researchers mainly use the three-dimensional reconstruction model of the temporal bone to improve the under...
