Getting started

AltaDB is a performant and flexible medical imaging cloud storage alternative to systems like AWS s3, Google Cloud Storage, and Orthanc. AltaDB provides a modern interface for storing DICOM data in the cloud, with medical imaging-specific features and organization. This document walks you through getting started with AltaDB.

AltaDB v0.0 is currently in Beta. We recommend experimental use with up to 100 series only.

Sign-up and organization creation.

  1. Head to https://preview.altadb.com/createaccount to sign up for a new account.

  2. You will require a confirmation code (sent to your e-mail) to complete account creation. If you don't receive a confirmation code, please check your spam.

  3. After creating an account, create an organization. The organization is the parent entity of AltaDB. All members and assets live inside an organization.

  4. Invite collaborators from the "Team" tab.

  1. AltaDB v0.0 has a single permission level - Admin. Admins have access to all assets within an organization.

  2. API keys give developers organization-wide access to all assets.

Dataset creation and importing data

In a single organization, you can organize your data into multiple datasets. A single dataset is a collection of several DICOM series.

All DICOM data is indexed and automatically organized into series within your dataset. Data will be organized by series using the Series Instance UID DICOM headers. Once indexing is complete, you can view all DICOM headers and search/filter your dataset by Series Instance UID, Study UID, or Patient ID.

AltaDB v0.0 will not maintain any folder structure you upload. The folder structure will be traversed, and individual series will be extracted and indexed.

AltaDB will ignore the entire series if it encounters an "invalid" DICOM file.

Importing data

  1. Create a dataset.

  2. Click on Import data, and drag & drop your DICOM files into the data importer. AltaDB v0.0 only supports direct upload through the browser.

  3. Once the upload is complete, AltaDB will index the DICOM headers and re-compress the DICOM pixel data with state-of-the-art compression. This process will take a few minutes for 10 series.

  4. You can monitor the status of your imports inside the "Import" tab.

Processing an import will take several minutes to completely index all DICOM headers and re-compress pixel data with state-of-the-art compression.

Viewing data

You can preview your images by clicking on the thumbnail. The simple viewer offers a view of the imaging axis and supports a few key functions:

  1. Change slice: Mouse scroll.

  2. Windowing: Right-click drag.

  3. Zoom: Left-click drag.

  4. Pan: Middle mouse drag.

Searching & filtering

You can filter your dataset by the following parameters:

  1. Series UID.

  2. Study UID.

  3. Import ID: A single import session gets assigned a unique import ID, which can be found on the "imports" page.

  4. Created by: The person who uploads the series.

  5. Imported at: The date range when the upload took place.
