## Import Data

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

<Steps>
  <Step title="Download Sample Data">
    Download and extract the [`DICOM-Lung-Lesion.zip` sample DICOM dataset](https://storage.googleapis.com/docs-media.encord.com/E2E%20Artifacts/DICOM-Lung-Lesion.zip).
  </Step>

  <Step title="Create a Mirrored Dataset">
    You’ll need to create a Mirrored Dataset before registering any data. Navigate to the **Datasets** section of the platform.

    <div
      style={{

paddingBottom: '50.847457627118644%',
position: 'relative'
}}

      <iframe
        allowFullScreen
        frameBorder="0"
        mozallowfullscreen=""

  top: '0',
  width: '100%'
}}
        webkitallowfullscreen=""
      />
    </div>
  </Step>

  <Step title="Import DICOM Series">
    <Info>
      This step assumes you want to import DICOM files from your local machine. To learn how to register cloud data [click here](/platform-documentation/Curate/add-files/index-register-cloud-data-cloud-sync).
    </Info>

    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.

## Create Ontology

<Tip>We recommend learning about [Ontology structure](/platform-documentation/Annotate/annotate-ontologies/annotate-ontologies) in Encord before creating Ontologies. </Tip>

1. Click the **+ New ontology** button in the **Ontologies** section.

<div class="flex justify-center">
  <img src="https://storage.googleapis.com/docs-media.encord.com/static/img/new-ontology-new.png" width="700" />
</div>

2. Name your Ontology `DICOM - E2E - Ontology` and provide an optional description.
3. Click **Next** to continue.
4. Define your Ontology structure.
