Release Notes

v2.1.2 — Hot Fix Release October 2, 2026

Features​

Encapsulated PDF Display Fix​

Hotfix 2.1.2 corrects a defect in which DICOM Encapsulated PDF objects did not display in AdvaView. No new functionality is introduced in this release.

Issue addressed: Opening a DICOM Encapsulated PDF displayed the message "No online PDF viewer installed" in place of the document, and the PDF series thumbnail did not display properly.

Behavior after this hotfix:

  • Encapsulated PDFs now render inside the AdvaView viewport using the browser's built-in PDF viewer, and the "No online PDF viewer installed" message no longer appears.
  • PDF series thumbnails now display correctly in the thumbnail panel.
  • Standard (non-PDF) image series load and display unchanged.
info

PDF rendering in this release depends on the browser's built-in inline PDF viewer. A future release will implement PDF.js-based rendering to convert the PDF into a standard viewable image.

v2.1.1 — Hot Fix Release September 23, 2026

Features​

Platform Not Supported Warning on iOS​

This patch release adds a clear "not supported" warning when AdvaView is opened on iOS devices. Previously, loading the viewer on an iPhone or iPad gave no indication that the platform is unsupported, and the application could hang the device.

Message displayed to users:

Device Not Supported AdvaView is not supported on iOS devices. This applies to all browsers on iOS due to Apple's WebKit requirement. Please access AdvaView from a supported desktop workstation using Google Chrome or Microsoft Edge.

Supported Platforms: AdvaView is supported on desktop workstations using Google Chrome or Microsoft Edge. iOS devices (iPhone and iPad) are not supported.

v2.1.0 - Production Release - Sept 17, 2026

Features​

Study Navigation & Thumbnail Rail​

AdvaView Standard 2.1.0-STD introduces an updated study navigation experience, significant enhancements to Hanging Protocols and multi-monitor setups, clearer loading indicators for advanced 3D/MPR reconstructions, and more intuitive measurement workflows.

  • Upgraded thumbnail rail and study list, now standard, featuring customizable sizing (75%–150%), flexible placement (Top, Left, Bottom), and smooth multi-monitor spanning.
  • Added Quick Drop for drag-and-drop image placement, displaying an instant preview of all available viewports across your displays.
  • Added hover-intent background prefetching for faster series previewing.

Hanging Protocols & Multi-Stage Navigation​

  • Added support for sequential study stages (e.g., current overview followed by prior comparisons) via the new toolbar Stage Navigator.
  • Protocols now scale seamlessly across up to 4 monitors, with automatic mismatch alerts.
  • Added Quick Build preset tools and more flexible study selection criteria for faster creation and management of reading layouts.

MPR & 3D Volume Feedback​

  • MPR viewports now display an in-viewport Rendering Progress (%) indicator during volume loading.
  • Image processing controls (e.g., Maximum Intensity Projection, slab thickness) are now held until volume data is fully loaded, ensuring accurate visualization.

Measurement & Annotation Tools​

  • Added universal cancellation of in-progress measurements via Escape or Right-Click.
  • Added support for the Delete hotkey and standard Enter confirmation dialogs for cleaner keyboard navigation.
  • Enhanced precision and geometry constraints for Cardiothoracic Ratio (CTR), spine labeling, and spline area/perimeter measurements.

Standard Mode Enhancements & Security​

v2.0.2 — Hot Fix Release August 14, 2026

Features​

Software Quality and Security Improvements​

This hotfix release focuses on software quality and security. It strengthens validation of medical imaging data, improves the accuracy of the software component inventory delivered for the product, updates older third-party utilities, and reviews newly identified third-party security findings.

Highlights

  • Improved imaging data validation — Added stronger checks for certain numeric values in medical imaging files to help prevent invalid data from being processed.
  • Improved file handling safeguards — Strengthened controls around how file paths are handled to reduce the risk of unintended file access or writes.
  • More accurate software inventory documentation — Updated the software bill of materials so it better reflects the components included in the production package.
  • Third-party software maintenance — Continued cleanup of outdated or deprecated software packages and review of newly reported third-party vulnerabilities.
v2.0.1 — Hot Fix Release August 6, 2026

Features​

Streamlined DICOM Support​

AdvaView has removed support for RT Structure Set (RTSTRUCT) objects. RTSTRUCT series will no longer appear in the thumbnail rail or be available for selection in the viewer. Studies containing RTSTRUCT data alongside other modalities (e.g., CT, MR) will continue to load and display normally for all supported series types. If a study contained ths SOP class AdvaView woudl report an error to teh end user before loading the rest of the series normally.

v1.2.10 — November 4, 2024

Features​

No changes were made to the DICOM viewer functionality in this release.

Platform Features​

  • Added a new data source selector dropdown on the Study List page, allowing users to quickly switch between available data sources without navigating to the settings page.
  • Added two new properties to the viewer configuration: hotkeys and groupHotkeyPresets.
  • For customers who embed FlexView and launch it in a standalone tab, added support for the following query parameters: flexviewToken, baseUrl, dataSourceToken, extraHeaders.

Known Limitations​

  • Saving measurements requires a STOW endpoint which may not be supported by some DICOMWeb datasources.
  • Some datasources (e.g., Amazon HealthImaging) may not support all search queries.
  • Not yet recommended for use on mobile devices.

Known Anomalies​

  • 231 — Stack image sync toolbar is out of sync with actual sync state

    • Description: When displaying a study with series that are auto-image synced, if the user turns "off" the stack sync, it will turn "on" instead. Selecting it a second time will actually turn it "off". When dragging display sets into view that are syncable, the image stack sync will be "on" in the new viewports, even though stack sync is "off".
    • Impact to Users: No impact. Auto-image sync can only be enabled in a hanging protocol, and it is not in use for any hanging protocols in FlexView Diagnostic. Hanging protocols are not configurable by users; thus, the end user cannot create this state.
    • Workaround: This anomaly does not affect users of FlexView Diagnostic. No user workaround is required.

  • 537 — Rounding error in onscreen display of some calibrated measurements

    • Description: There is a slight discrepancy in displayed measurements due to a computational rounding error. This occurs when the software calculates the length of a line in pixels and converts it to millimeters based on the predefined pixel-to-millimeter ratio.
    • Impact: This issue does not occur consistently but may be more noticeable at certain levels of image zoom. The rounding error is minimal, generally within +/- 1% of the actual line length. For example, a calibrated measurement of 10mm might display as 9.99mm.
    • Workaround: No workaround needed; this anomaly will be fixed before the device is available to users.
v1.2.9 — June 13, 2024

Features​

  • Hotfix — Implemented a fallback for TransferSyntaxUID when it is missing in DICOM metadata, allowing images with unknown TransferSyntax to still be displayed.

Known Limitations​

  • Saving measurements requires a STOW endpoint which may not be supported by some DICOMWeb datasources.
  • Some datasources (e.g., Amazon HealthImaging) may not support all search queries.
  • Not yet recommended for use on mobile devices.

  • 537 — Rounding error in onscreen display of some calibrated measurements
    • Description: There is a slight discrepancy in displayed measurements due to a computational rounding error. This occurs when the software calculates the length of a line in pixels and converts it to millimeters based on the predefined pixel-to-millimeter ratio.
    • Impact: This issue does not occur consistently but may be more noticeable at certain levels of image zoom. The rounding error is minimal, generally within +/- 1% of the actual line length. For example, a calibrated measurement of 10mm might display as 9.99mm.
    • Workaround: No workaround needed; this anomaly will be fixed before the device is available to users.
