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 present application discloses a temporal bone spatial data processing and positioning method, device and electronic equipment. Wherein, the processing method includes: based on the first image containing the bone canal structures of the bilateral lateral semicircular canals, determining a reference plane between the bone canal structures of the bilateral lateral semicircular canals; Symmetric feature points; determine the origin of coordinates and the median sagittal plane according to the corresponding symmetrical feature points of the bilateral lateral semicircular canal bony canal structures; use the voxel point information corresponding to the bilateral lateral semicircular canal bony canal structures in the first image to determine the transverse axis plane ; Determine the coronal plane according to the transverse axis plane and the median sagittal plane; establish the temporal bone spatial coordinate system based on the coordinate origin, the median sagittal plane, the transverse axis plane and the coronal plane. After the user triggers a calibration request for a point in an image, the embodiment provided by this application can automatically determine and display the coordinate value of the point using the temporal bone space coordinate system, providing a good foundation 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...
