# Importing Multiple Single-Frame DICOM Files as One Multi-Page Asset

You may group together single-frame 2D DICOM files and upload them to Hub as a single multi-page asset, where each page is one of the DICOM files uploaded.

{% hint style="warning" %}
This functionality is only available for single-frame 2D DICOM files.
{% endhint %}

You may upload such multi-DICOM assets using the *Cloud Import* method outlined below.

## Uploading Multi-DICOM Assets

Prepare a JSON like the following, where each URL points to a DICOM you'd like to include in the asset. The order of the URLs will determine the order in which images will be presented to the annotator as pages.

The following JSON will import two assets of four DICOMs each:

```json
[
  {
    "externalId": "my-asset-external-id-1",
    "dataset": [
      "https://url.com/65c18c8b-4513-4a0a-b876-1aeb2e0908ec.dcm",
      "https://url.com/b0b70590-e4cc-42ef-8537-3ee3f7917fed.dcm",
      "https://url.com/38e11364-1ce0-417a-9e38-436468c555ce.dcm",
      "https://url.com/eff59355-03bd-447f-aa47-46028f90c2e6.dcm"
    ]
  },
  {
    "externalId": "my-asset-external-id-2",
    "dataset": [
      "https://url.com/65c18c8b-4513-4a0a-b876-123456789012.dcm",
      "https://url.com/b0b70590-e4cc-42ef-8537-234456566787.dcm",
      "https://url.com/38e11364-1ce0-417a-9e38-876345383488.dcm",
      "https://url.com/eff59355-03bd-447f-aa47-319485019239.dcm"
    ]
  }
]
```

From your project dashboard, go to the *Assets* tab and click on *Add Data*. Then, enter the *Cloud Storage* section and drag and drop your JSON on the file upload field. Then, press on *Upload*. Your multi-DICOM asset(s) will be uploaded.

If your DICOM files are in a private bucket, ensure you select the appropriate [storage integration](/data/storages.md) from the list on the left.

Assets uploaded this way will have a navigation widget at the top, allowing annotators to navigate between the DICOMs.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.imerit.net/data/importing-assets/bundled-assets/importing-multiple-single-frame-dicom-files-as-one-multi-page-asset.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
