--- license: afl-3.0 tags: - medical size_categories: - 100M<n<1B --- # Dataset for AVS-Net Pre-training The dataset utilized in the pre-training of the AVS-Net: Attention-based Variable Splitting Network for P-MRI Acceleration model, developed by Y Zhang, J Li, Z Wang, J Duan, and J Li, incorporates data from five distinct protocol sequences. These are: - (coronal_pd)Coronal Spin Density-weighted without Fat Suppression - (coronal_pd_fs)Coronal Spin Density-weighted with Fat Suppression - (sagittal_pd)Sagittal Spin Density-weighted - (sagittal_t2)Sagittal T2-weighted with Fat Suppression - (axial_t2)Axial T2-weighted with Fat Suppression The dataset is structured on a slice-by-slice basis, with each slice containing 20 cases. Each case is comprised of two files: rawdata*.mat and espirit*.mat. The dataset's structure can be outlined as follows: ## Dataset architecture: - name: /rds/projects/d/duanj-ai-in-medical-imaging/knee_fast_mri - Protocol: [coronal_pd, coronal_pd_fs, sagittal_pd, sagittal_t2, axial_t2] Approximately 40 slices per protocol, each slice containing 15 channels, with a height and width (HW) of (640, 368) ``` knee_nyu - axial_t2 coronal_pd(X) coronal_pd_fs sagittal_pd sagittal_t2 | | | | | - [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], [11, 12, 13, 14, 15, 16, 17, 18, 19, 20] masks | | - [train] [val] | | - espirit*.mat(1-40), rawdata*.mat(1-40) *_masks.mat ``` In this structure, each protocol has approximately 40 slices, each consisting of 15 channels. The dimensions of the data are 640x368 (height x width). For each protocol, the slices are further divided into two groups: the training set ([train]) and the validation set ([val]). The training set includes the espirit*.mat and rawdata*.mat files for each slice, while the validation set contains *_masks.mat files. ## Dataset Usage > For a standalone knee dataset download, use `git lfs`(<https://git-lfs.com/>) to download from the `huggingface` datasets(<https://huggingface.co/datasets/AVS-Net/knee_fast_mri>): ```bash # Make sure you have git-lfs installed (https://git-lfs.com) git lfs install git clone -j8 git@hf.co:datasets/AVS-Net/knee_fast_mri ``` ## Known Issues and Resolutions - 1. Network Connection Issue For enhanced network connection quality, it is recommended to employ the `ssh` protocol instead of `https`. ```bash # Rather than utilizing `https://huggingface.co/datasets/AVS-Net/knee_fast_mri` # Clone the repository using `git@hf.co:datasets/AVS-Net/knee_fast_mri` # As an example: git clone -j8 git@hf.co:datasets/AVS-Net/knee_fast_mri ``` - 2. Interruptions During Download Certain error messages may appear during the download process due to interruptions. These errors can include: ``` error: ... : cannot add to the index - missing --add option? batch response: Post ... : read: connection reset by peer error: failed to fetch some objects from 'https://hf.co/datasets/AVS-Net/knee_fast_mri.git/info/lfs' ``` Following the instructions below allows for the handling of these interruptions. ```bash # Navigate (`cd`) to the directory containing the `lfs` folder # Intead of using `git pull`, # Use `git lfs pull` to resume the download progress for `lfs` projects git lfs pull ``` Please note that this process will resume the download from where it was interrupted, thereby ensuring the integrity of your downloaded data.
