Dental MRI Motion Correction
Description
This is the demo datasets that can be used with the open-sourced code for the Motion-Robust Dental MRI: https://github.com/ZihanNing/dental_MRI_motion_correction
The raw data was collected from a 0.55T MR scanner (MAGNETOM Free.Max, Siemens Healthineers, Forchheim, Gemany) with a PD-weighted SPACE sequence (using DISORDER trajectory) from a 29-year-old male healthy volunteer under head and mandibular movements. The sequences will be open-sourced on Siemens' C2P platform soon.
To use with the open-sourced code, please put the raw into a generated subfolder under /Studies-deploy (e.g., /Studies-deploy/1). Then modify the path in the main script 'batch_dental_multiple.m' to align with the raw path. For example:
rootFolder = './Studies-deploy';
studiesFile = fullfile('./Studies-deploy', 'studies.m');
numCases = 1;
caseList = [1];
- Trained nnUNet models for teeth segmentation (Dataset003_Dental_autolandmark_PDwMPRAGET2w.zip) and head segmentation (Dataset004_Dental_headseg_PDT1T2.zip)
To run the segmentation-enabled workflow, you will need nnUNetv2 installed in a Python environment. Please download the two models, unzip, and place them under your local nnUNet_results directory.
In batch_dental_multiple.m, these are currently set through the local variables CONDA, ENVNAME, and NNUNET_BASE. You will likely need to edit these paths for your system before running the workflow.
For detailed instructions of using the dataset, please refer to the linked git repo: https://github.com/ZihanNing/dental_MRI_motion_correction
