FEATURES

File Type Support

Added automatic file type detection for .avi video files. Files with the .avi extension are now automatically classified as video files upon upload.

Video Annotation

Updated CVAT integration to the latest version (2.44.1+) to provide the most current features and improvements for video annotation workflows.

Viewers

V3 Viewer
  • Annotations:
    • Configure pre-defined colors for annotation labels to maintain consistency across reading sessions and enable standardized workflows within your organization.
    • Annotations now highlight in the viewport when you hover over them in the measurement panel, making it easier to locate and review specific measurements.
  • Segmentations:
    • Export ROI statistics as CSV files for downstream analysis and integration with statistical analysis tools.
  • Ophthalmology Imaging - The V3 Viewer now includes specialized tools for ophthalmology workflows:
    • RGB Channel Filter for Fundus Images: Select individual color channels or manually adjust each channel's intensity to enhance visualization of pathology in color fundus images.
    • OCT Stretch Tool: Vertically stretch OCT images to improve definition and measurement accuracy of retinal layers.
  • Enhanced Synchronization:
    • Scrolling can now be synchronized between viewports displaying the same image dataset, even when the DICOM tags ImagePositionPatient or ImageOrientationPatient are missing.

FIXES

Data Management

  • Fixed an issue where restoring a prior version of a file added via Bulk Import could result in the file no longer being visible.
  • Improved LDAP query performance for LDAP Sync operations.
  • Improved the performance of the project list interfaces by using pre-calculated subject and session counts.
  • Fixed an issue of degraded performance after site upgrade due to a failed index rebuild.

Data Transfer

External Storages
  • Fixed an issue with File System type External Storages where the storage status check would fail due to incorrect user context when checking directory permissions.
Bulk Export
  • Fixed an issue with Bulk Export where exports of very large projects would fail due to memory issues when reading large export snapshot files (3-4GB).
  • Fixed an issue where creation of access logs for projects with many subjects was too slow due to a missing index.

Gears and Compute

  • Resolved an issue where the jobs log archiving was not occurring for sites using Azure Workload Identity.

Python SDK

  • Fixed an issue where the get_daily_usage_range_report() function returned results outside the requested date range.
  • Fixed an issue preventing analysis input files from being downloaded using the SDK download() function.
  • Fixed an issue where modify info and classification functions did not automatically retry failed requests.
  • Corrected SDK documentation for the Metadata parameter in container file upload functions.

Smart Copy

  • Improved retry logic and logging for Smart Copy operations that fail due to intermittent network errors.

Viewers

V3 Viewer
  • Annotations fixes:
    • Fixed an issue where length measurements were not accurate on Ultrasound data with single SequenceOfUltrasoundRegions DICOM sequence.
    • Fixed an issue where annotations could not be saved when it included an annotation arrow.
    • Fixed an issue where area measurements would sometimes be missing in the annotation quick view.
  • Segmentations fixes:
    • Fixed an issue where segmentation edits would trigger computing of 3D rendering even when no 3D viewport was being displayed.
    • Fixed an issue where switching between common layouts and advanced layouts would trigger duplicate notifications for conversion of segmentations to 3D.
    • Fixed issues with undo/redo functionalities after deleting ROIs.
  • Other fixes:
    • Fixed an issue where the viewer configuration would no longer be applied after opening images from the session list.

Web App

  • Fixed an issue where the Move Acquisition dialog allowed invalid session selections when changing projects.
  • Fixed an issue where the bundled video player was available for MTS files that it does not support.
  • Fixed an issue in the Jobs Log UI where launching a viewer on job input or output files resulted in the viewer content being obscured by the job detail panel.
  • Fixed an issue where clicking "Edit Query" after executing an Advanced Search query would clear the query.
  • Fixed missing icons in the bundled text editor's search/replace feature.
  • Fixed an issue where the API Key expiration alert failed to appear on login.
