Coming Soon - June, 2023

Flywheel 16.19 Release

 

16.19.0

NEW Features

‘Enhanced’ API Keys

• A new format for all new API Keys (User & Device) created with 16.19.0 and later
• Makes use of stronger storage security measures
• Supports tracking “Last Used” date/time and will support additional security features in the future. 
• Existing 'Legacy' API keys can can be used with SDK & CLI versions prior to 16.19.0 and later.
• Enhanced API Keys can be used with SDK & CLI versions prior to 16.19.0

Enhanced API Keys - Device Settings UI Changes

• Device creation is now independent from API Key creation.
• Disabling a device behaves the same as disabling a user
  • The device will immediately no longer be able to authenticate with the Flywheel service
  • Disabling and re-enabling will not cause associated API Keys to be revoked or regenerated.
    

Enhanced API Keys - Compatibility

• Existing ‘Legacy’ API Keys and CLI & SDK versions in use will work after the Flywheel 16.19.0 service update.
• Flywheel Enterprise service will end all support for Legacy API Keys in a future version release - no sooner than December 2023.
  • To ensure compatibility replace all usage of Legacy API keys with the new 'Enhanced' API Keys.

Conceal API Keys by Default

• With 16.19 API Keys will be not be viewable after their initial creation. Concealing API Keys by default reduces the likelihood of unintentional exposure.

Updated 'Save' Experience

• Making updates to multiple sections, or navigating away from the current Web UI view was liable to unsaved changes being unintentionally lost. To mitigate this, we are introducing the following features:
  • Saving changes will now apply to all unsaved changes in a Web UI view, rather than each individual section.
  • Users will now get a warning when navigating away from a page that has unsaved changes.

Granular Purge of Deleted Files

• To better manage storage costs in relation to data recoverability requirements, Flywheel can now be configured to retain certain derived data for shorter periods after a user marks them for deletion.

X/Y Aspect Ratio Stretching

• For image review & annotation workflows on anatomy that is difficult to assess due to how close the features are, such as tissue planes, the viewer now supports stretching the aspect ratio.

Blinded QA Review of Reader Tasks

• For blinded reader studies, it is important to not only blind the readers from one another but also to blind the QA personnel who are interpreting and comparing readers’ data. This is now possible.

Visualization of DICOM SEG

• As Flywheel continues to expand its file type support in the viewer, DICOM SEG visualization is now supported in the viewer.

Option to Export as DICOM SEG

• Following our addition of SEG visualization support, we now also support exporting mask segmentations generated in the viewer as DICOM SEG.

High-Level Visibility Toggle for ROIs

• In order to better support reader task QA workflows in the viewer, a high-level visibility toggle option has been added.

Fundus Ring Overlay Tool

• For color fundus labeling workflows, the ability to define a fundus ring overlay is critical for understanding the clinical impact of certain findings. This is now possible in the viewer.

Lock Circle ROI Diameter

• For workflows that need a simple “click & annotate” option with consistent area captures, the viewer now supports locking the circle ROI diameter.

FIXES

• Viewer is now keeping active tool when there are multiple defined.

• Tool selected from Annotate menu is no longer getting switched when multiple "measurementTools" are configured for a study form question.

• Manage Project Settings permission now allows user to modify the deidentification Profile.

• Resolved issue with Project permission role migration (v14 to v16 upgrade)

• Jobs Log - corrected filtering on dates

• Corrected descriptions of gear version differences when downgrading gear.

• Red (R 100%, G 0%, B 0%)
• Green (R 0%, G 100%, B 0%)
• Blue (R 0%, G 0%, B 100%)

We also support hotkey definition for resetting back to RGB

Flywheel 16.17 Release

 

16.17.0

NEW Features

Viewer

Hanging Protocol Support for Web Images

• With additional image labeling functionality being added for web images, the need for displaying multiple in a custom HP was clear

125um Tooltip Marker UX Enhancements

• Added the proximity cursor functionality to both Zoom and Pan tools
• “proximityRoiCursor” now has a “lineStyle” option to display the cursor as either ‘solid’ or ‘dotted’

Options for ignoring saved user settings in the viewer

• Improves the user experience for QA reviewers of reader tasks 
• Currently, the system saves the settings applied in the viewer when they last saved the task
  • Zoom, rotation, W/L, slice location, etc
• With the historical behavior, when a QA person loads a task (or multiple tasks), they were getting a poor UX while navigating the tasks and reinstating different users settings.  As such, we have provided the following solutions:
  • Default behavior is to ignore when multiple tasks are launched simultaneously
  • URL Component: “ignoreUserSettings=true”

FIXES

• Improved form field and response display/saving
• Enabled edit mask option on first click and improved saving of edited mask
