The invention discloses a method for three-dimensional reconstruction of the temporomandibular joint. The method is to fuse magnetic resonance data of different sequences in the temporomandibular joint area, and perform three-dimensional modeling according to the fused data, so as to finally obtain a reconstructed Temporomandibular joint soft and hard tissue; wherein, the magnetic resonance data includes oblique sagittal data and coronal data. The method of the present invention uses multi-sequence MRI image recognition and information extraction and fusion technology to accurately and quickly obtain high-quality magnetic resonance with several times the amount of original data for the region of interest, that is, the temporomandibular joint region at a lower cost. Image data, and then use more realistic data for 3D reconstruction. The invention can overcome the disadvantages of less amount of magnetic resonance data, poor quality of direct reconstruction model and filling distortion of computer simulation.
Description
technical field [0001] The invention relates to the technical field of medical image processing, in particular to a method for three-dimensional reconstruction of temporomandibular joints. Background technique [0002] At present, a known three-dimensional reconstruction method is based on MRI (magnetic resonance imaging) three-dimensional reconstruction method of difficult airway, including the following steps: ① DICOM image acquisition and DICOM format file conversion: based on MRI, supine position and backward position Scan the scanned sagittal MRI image in DICOM format, burn it on a CD, and mark the subject number for future use; ②3D digital model reconstruction: import the DICOM format data file into Mimics10.01 software, and automatically distinguish between scans Direction, set the corresponding viewing direction, and read in the data; determine the tissue range that needs to be three-dimensionally imaged; use the software to automatically identify the edges of the re...
