Import Data

In this section we’re going to download and register our data.

1. Download Sample Data

   Download and extract the DICOM-Lung-Lesion.zip sample DICOM dataset.

2. Create a Mirrored Dataset

   You’ll need to create a Mirrored Dataset before registering any data. Navigate to the Datasets section of the platform.
3. Import DICOM Series

   This step assumes you want to import DICOM files from your local machine. To learn how to register cloud data click here.

   Now import the sample data from DICOM-Lung-Lesion.zip into the Dataset E2E - Dataset - DICOM. The platform automatically detects that all files belong to the same DICOM series and groups them into a single data unit.
