Cardiac Substructures Segmentation

This notebook provides a minimal working example of PlatiPy, a tool for the segmentation of the heart and 17 cardiac substructures from non-contrast CT images. The model leverages both Deep Learning and Atlas-based techniques, and was trained using a dataset of 20 all-female breast cancer patients.

We test PlatiPy by implementing an end-to-end (cloud-based) pipeline on publicly available chest CT scans hosted on the Imaging Data Commons (IDC), starting from raw DICOM CT data and ending with a DICOM SEG object storing the segmentation masks generated by the hybrid pipeline. The testing dataset we use is external and independent from the data used in the development phase of the model (training and validation) and is composed of a wide variety of image types (from image acquisition settings, to the presence of a contrast agent, to the presence, location and size of a tumor mass).

The way all the operations are executed - from pulling data, to data postprocessing, and the standardisation of the results - have the goal of promoting transparency and reproducibility.

You can find the notebook here.
