DICOM Labeling Editor

Overview of the DICOM Labeling Editor interface on Ango Hub

This page is temporarily out of date. We have recently merged our multi-page DICOM and video editors, so that they share the same interface. Thank you for your patience as we rewrite this page.

In the meantime, you can refer to the page on the video editor, which is nearly identical to the DICOM editor.

Ango Hub provides a labeling editor with which single- and multi-page DICOM files can be annotated.

This article will exclusively go over Ango Hub’s DICOM labeling interface. Features common to all labeling editors (audio, image, PDF, and text) are instead explained here.

Overview of the DICOM Labeling Editor in Ango Hub

DICOM Interface Elements

Pages Bar

The back and forward arrows allow you to move backwards and forwards one page at a time. The slider allows you to move quickly between pages by clicking on it dragging it to find the frame you need. If you already know the number of the page you'd like to visualize, enter it in the text box on the right and press Enter to immediately jump to it.

Patient and File Information

If embedded in the DICOM file, patient data such as Patient ID and Patient Name will be shown. If present, the thickness of the slices in the DICOM file is shown.

How to Annotate DICOM Files

Annotating DICOMs is similar to annotating images and videos since a single-page DICOM is, in essence, an image, and a multi-page DICOM a video. There is, however, additional functionality to consider.

The following are the labeling tools supported on DICOMs:

From the Tools panel on the left sidebar, select a supported labeling tool. Then, follow the instructions found on each tool's docs page, linked to above.

If no tools are present in the project, only answer the questions in the Classifications panel.

When done, move forward to the next page and repeat the process until all pages are labeled.

Nested Questions and Classifications

If the labels have nested questions, right-click on each label and click on the menu item that appears to see and answer the nested questions.

If classification questions are present, you may answer them from the Questions panel on the left sidebar.

Annotating Multiple DICOM Files at Once

For information on how to import multi-DICOM assets, please consult this docs page.

Entering Focus Mode

When multiple DICOM files are displayed on screen, you may choose to focus the layout on a smaller number of them.

For example, in this asset, we have eight DICOM files displaying at once:

While holding Alt (Option) on your keyboard, click on the DICOMs you would like to focus on. A button will appear:

Clicking on it will enter "Focus Mode" with the selected DICOMs, where they will be displayed in their own, larger, layout:

To exit Focus Mode, click on "Default" again.

Changing Window Levels

By clicking on the "Window Level" icon, windowing level options will appear.

Keyboard Shortcuts

A full list of keyboard shortcuts is available by clicking on the Keyboard button on the right side of the top bar:
