Layout & Multiple Volumes

The RedBrick AI annotation tool layout can be customized to display your volume(s) as needed. If your tasks have multiple series, you can view all the series together, along with MPR, 3D, and MIP views.
The layout is configurable only with 3D images, or when there is more than 1 series in your task.

Default Layout

For tasks with a single series, the annotation tool will be in MPR (Multi-planar Reconstruction) mode by default.

For tasks with multiple series, the annotation tool will display all the imaging plane for all series (up to 9).
Axial plane displayed for all four series
You can modify the default layout for a project using hanging protocols.

Modifying your layout

In the Layout context panel, you will be able to select your view layout - you can display up to 9 volumes/reconstructions at once. When the Layout settings are toggled, you can drag and drop series/reconstructions from the context panel to construct your viewports.
Configuring your annotation layout

Multi-planar Reconstruction

You can toggle multi-planar reconstruction for any volume using the actions dropdown on the viewport. Toggling the MPR mode will re-adjust your layout to display a single volume with its reconstructions. You can also manually drag and drop the reconstructed views from the Layout Context Panel.


Once in MPR mode, activate crosshairs from the topbar, or with the c shortcut to synchronize the reconstructed views. You can also use the selection tool to select the visible crosshairs. Double click anywhere to move the crosshairs to the cursor location, or click and drag the crosshairs to adjust.
The MPR crosshairs will be visible but inactive in all modes by default. You can hide crosshairs outside of the crosshairs tool through the command bar (Toggle Permanent Crosshairs) or with Shift+Cmd/Ctrl+c.

Max/Min Intensity Projection (MIP)

Maximum intensity project takes several slices of 3D data and merges them together. This feature is available as a separate viewport.

Activating MIP

Open the layout panel -> Click a series to expand the view options, the MIP option is at the bottom, you can drag it onto a viewport.

Using MIP

Once activated, you will not be able to paint or draw labels here, but you will be able to use this a reference visualization for annotating the main view. MIP is only available along the imaging axis (not with MPR). Use the slider on the viewport to adjust the slab thickness.
