Cardiac magnetic resonance CINE images of Sus scrofa
This is a data set with end-systolic and end-diastolic CMR CINE images of 11 individual pigs at 4 time points. Some of them received a treatment (induced myocardial infarction), others did not (control). See data/metadata/measurements.tsv.
This is a DataLad repository. You can clone the repository with plain git, but we recommend using datalad. After cloning all data files are just symlinks. In order to get the actual data, download the archive at zenodo: https://doi.org/10.5281/zenodo.7684034, unpack it and add it as a sibling. Then use datalad get to get the actual content of the files.
These commands can be used, to clone the latest version from GitHub and add the data from zenodo:
bash
git clone https://github.com/chfc-cmi/cmr-cine-sscrofa
cd /tmp
wget https://zenodo.org/record/7684034/files/cmr-cine-sscrofa.zip
unzip cmr-cine-sscrofa.zip
cd -
cd cmr-cine-sscrofa
datalad siblings add -s data --url /tmp/cmr-cine-sscrofa
datalad get data
Data
In addition to the MR images manual segmentation of the left ventricle and myocardium are provided.
The raw data is provided in the form of DICOM files and Contour files (format used by Medis).
Conversion to png
Both images and segmentation masks are also provided in png format with a unified naming scheme.
For reproducibility, the conversion steps are documented below.
DICOM to png
DICOM files are converted to png using the program code/dcm2pnm, the naming of png files is derived from the DICOM folder structure and file names. All steps are bundled in the script code/dcm_to_png.sh.
Contour to png
The conversion is done in two steps. First the con files are converted to tsv files (and a resolution.tsv file is created with number of columns, rows and slices per measurement). This is done using code/con_to_tsv.sh.
Then these tsv files are converted to png (filling implicitly missing slices but not missing timepoints/frames with empty masks) using code/tsv_to_png.py.
Usage
This data is used in the cmr-seg-tl-sscrofa project to train a deep learning segmentation model.
