RedBrick 1.0

​

Workspaces and cohort creation

We are introducing a new concept called “workspaces.” These workspaces allow you to group similar projects and share data between them. 

We also have a new data quality control layer called “cohort creation” (previously soft-launched), making it easy to manage your data with searching, filtering, and summarization tools. Read more about cohort creation here: https://redbrickai.com/cohort. You can still create standalone projects as you are currently used to.

​

Introducing RedBrick AI Boost

The RedBrick Boost add-on is a self-hosted container that enables tight integration of AI assistance tools into the RedBrick AI ecosystem. At launch, Boost supports two features: FAST’s server-side component and an automatic CT scan pre-segmentation model. 

Since launching the FAST segmentation tool last year, we have received many requests for the ability to self-host this for privacy, compliance, or performance reasons. Starting July 2024, we will deprecate the RedBrick-hosted FAST and replace it entirely with Boost. Boost will be charged at an hourly metered rate to scale alongside your GPU usage. Get in touch with us at support@redbrickai.com to get started with Boost.

​

Updated contouring tool suite

We’ve upgraded our contour tool to offer many more refined annotation capabilities that don’t exist in other browser-based tools. With the new contouring tool, you will be able to: 

• Edit any mask created as a contour. Previously, an explicit rasterization step was required to go from contour to mask. Now, there is a fluid & automatic transition between contour and mask. 

• You can now hover over an arbitrary edge of a contour and interactively drag by a node to edit contours. 

The existing contouring tool has the following changes to it: 

1. The old contour tool is now the “interpolate tool,” allowing you to select an existing contour on two slices and interpolate between them. 

2. The old pen tool is now the “3D scissors” tool, which retains only the best part of the pen tool for 3D viewing. 

​

Updates to project workflows

Several long-awaited features have been added that unlock new capabilities for your project’s workflow. 

1. Task clawback: Annotators who have finalized a task can now “clawback” if a reviewer has not started reviewing it. This should help with a typical scenario where an ADMIN had to go in and manually reject the task to send it back to an annotator.

2. Send task to stage action: You can now send any task to any stage at any time.

3. Archive stage: A new way to remove tasks from your projects without deleting them permanently. The most common use case would be discarding bad-quality images from the annotation queues. 

4. Pre-review: A new review stage is now implemented at the beginning of your project to assess the quality of your data. Any rejected tasks will be moved to the archived stage.

5. Pre-label: A new duplicate annotation stage for miscellaneous use cases such as SDK pre-labeling.

6. Overwrite annotations SDK method: A new SDK method enables you to overwrite annotations at any point in the pipeline. This is useful in many active learning workflows. 

7. Task duplication: A new project configuration that automatically duplicates your tasks. This allows you to have the same image annotated by multiple users and independently reviewed. This was a common shortcoming of our consensus/super truth framework.

​

​

Comment Pins

Now you can add a pin to a comment. This allows reviewers to be specific about where in a series they are referring to. You can create multiple comments and multiple pins. The labeler will be warned if they try to submit without resolving the comments.

​

Other stuff

• Add an optional endpoint field to s3 storage integration, this allows for the use of S3-API compatible storage methods (such as MinIO)

​

ROI Tools

In order to better handle the tagging of Regions of Interest, we have added rectangle and ellipse tool support for annotating on 3D volumes. At this time these ROI tools should be considered experimental. This feature will report area measurement and intensity statistics of the targeted region. To use this, add the ellipse or box type to your taxonomy. You will only be able to draw these types on the imaging axis.

​

Other changes:

• Now 2D versions of tools can be used alongside label mirroring.

• Performance improvements when loading a multipart DCM file (Video)

• Fix issues related to rotating 3D views

• Fix color of contour labels not getting updated with vibrant mode or category change

​

Addition of new Project admin role

“Labelers” have been renamed to “Member” and can now be upgrade to see the Admin dashboard in a project. Check Here for more info.

​

Minor changes:

• Enable threshold preview where previously disabled (label mirroring and oblique planes)

• Fix an issue where Members could not access their Account settings page

• Minor tweaks to improve rendering performance in the DICOM viewer

​

”Draft then Finalize” workflow for Label stage

Now when you are annotating tasks, you can choose to first submit as a draft. This allows you to build up a batch of “pending finalization” tasks that you can then finalize all at once. Read more here

​

Smart contour selection tool

When using the contour tool, hold down the “alt” or “option” keys to automatically select a region at the cursor.

Click to create a contour from that selection. For contours that have wavy edges, you can click and drag while holding “alt” to do some smoothing of the contour.

​

Add a review stage to an existing project

Under project settings, you can now add a new review stage to your workflow. You won’t be able to delete any, but if you want to skip a stage, just set the review percent to zero.

Minor changes and bug fixes:

• Significantly faster pen tool and contour tool conversion to mask.

• Show “corrected” as a part of task history, before only accepted/rejected were showing even when a task was corrected.

• Modifications to the display of left side bar on annotation tool.

• Handling special chars in CSV export.

• Show number of assigned tasks in project workforce/

• Improvements to API speed.

• Fixes for pen tool in safari.

• Disable filter on data page while tasks are loading.

• Show “API key” in assignment on data page, this is to support tasks that are annotated via SDK.

​

Contour Tool

Do you have a large organ to segment that doesn’t work well with thresholding? We have created the manual contour tool to allow you to quickly draw outlines of your regions, then interpolate between slices.

To activate it:

• Select the tool from the top bar, or

• Press the “k” hotkey, or

• Search for the Contour tool in the command bar

The contour tool works very similarly to the pen tool. To get started click on a 2D viewport. You can click and drag or add points one click at a time. To close click the end node. You can then change the slice and repeat the process. If you skip slices, the in between slices will be interpolated.

To edit, simply hover near the edge of your region and click and drag to draw a new segment. Editing an interpolated contour will make that contour a key point that will be used for interpolation of the nearby slices.

Important: When you are done with your contour, you will need to convert it to a pixel mask. This process is called “rasterization.” There is a button on the right panel to do this, or you can use the Shift+Enter hotkey.

​

Single instance per series

In order to improve the annotation experience and the correctness of exported data, a single segmentation instance will now only apply on a single series. The series name will show up on the label object now.

​

Who does this affect

If you are labeling data on a single series (Xray or other images, Ultrasounds or other videos, or single CT scans) then this change will not affect you.

This will only affect you if you are annotating studies with multiple series AND you use the same instance on more than series (i.e. creating a single label object and annotating a T1 and T2 MRI scan).

​

What you need to do:

Nothing, however you will now need to create separate instances for each series with the same category that you want to annotate. Data that was annotated previously will be automatically processed to determine if which series have a given label.

​

Minor changes:

• Adds software version to the bottom of the Accounts page

• Adds unique icon to labeler queue for identifying tasks

• Improvements to 3D hole filling execution time

• Tweaks to improvement thresholding range adjustment

• Editing category names, attributes, etc. after taxonomy creation.

• Series and study level classification.

• One-click label creation workflow.

• Easily accessible label attributes.

• and more!

See a more comprehensive overview of Taxonomy V2 vs. Taxonomy V1 here. See more detailed documentation about Taxonomy V2 here.

For the time being, we will continue to support Taxonomy V1, but will eventually plan to deprecate it.

​

User tagging

Add tags to your team members. This is useful for managing different teams and different roles such as “Radiologist” or “Radiographer”. Head over to the Team tab to add custom user tags, and view them while hovering over a User Avatar.

​

Labeling Queue

We’ve increased the size of the labeler queue to show up to 100 tasks that are assigned to you and up to 100 tasks that you’ve skipped (for a total maximum of 200 tasks).

The legacy annotation tool has been deactivated on all projects.

​

Hanging protocols

Write a custom Javascript function to automatically set your annotation tool’s layout and viewing settings. Using Hanging protocols, you can standardize the viewing workflow/layout for all members of your team. Here is a list of some of the parameters you can define:

1. Layout dimensions.

2. Display position for a series.

3. Which reconstructed plane to display.

4. View flipping.

5. Intelligent Syncing activation by default.

Please read more about the hanging protocol, and how to activate it here.

​

Other changes

Remove “Large Data Mode” as a layout, this was a performance improvement to only render a single image when a series was larger than approximately 200 slices. Now, even large data will follow the hanging protocol script.

​

Intellisync

Intellisync unifies support for synchronizing different series in a single task/study. Intellisync is available in tasks with more than 1 series/volume. When intellisync is activated, the scroll position is synchronized across series in your study.

Activate Intellisync from the viewport actions dropdown, or using ctrl/cmd + a. Activate Intellisync for all volumes using cmd + shift + a.

Read more about intellisync here.

​

Fixes

• Fix a bug where using the mouse for windowing while having label mirroring activated changed the window level/width for the wrong series.

You can now adjust the review percentage without needing to create a new project. This is available for all projects with a review stage under general settings of a given project. However, please note that for projects from before September 14 that contain a “task-random-filter” stage, this does not apply.

For teams that want to handle all task assignment manually, you can now disable our automatic assignment engine for each project stage individually.

​

Other changes:

• Improvement to undoing (Cmd/Ctrl + z) after deleting a segmentation label

• Misc minor improvements to the brush tool “shadows” shown on reconstructed viewports

​

Add a dropdown menu on the viewport top right with:

- action for activating segmentation mirror (see below)
