Release date: 1/30/2024
Features:
- New Feature: Segmentation panel with a range of interactive tools like brushes, erasers, shapes, and thresholding tools. These tools empower you to create, modify, and perfect your segmentations effortlessly.
- New Feature: Cornerstone 3D now fully supports NIFTI data.
- Redesigned the side panes, which maximizes space for your content while minimizing the room occupied by the panel header.
- New Feature: Added button and ability to download segmentations as Radiotherapy Structure Sets (RTSS) or DICOM SEG in segmentation panel.
- New Feature: Added WindowLevel component with histogram and colormap for voi range and transparency control, and ViewportWindowLevel component for calculating and displaying histograms for volumes.
- Improved performance for metadata retrieval in large studies
- Removed unit from measurement display when unit does not exist
- New Feature: Added a new JSON configuration option use16BitDataType that defaults to false, if set to true the viewer will attempt to use 16 bit rendering, greatly reducing memory consumption.
- Added proper error handling to fix infinite loading issue and ensure correct logging of errors in the console for the "DisplaySet Messages" feature.
- New Feature: Added the option to lock a segmentation or measurements in the side panel to prevent editing.
- Added server and study fallbacks for unreachable servers and problematic studies, along with a check for SeriesInstanceUID filter in the URL.
- Refactored storePresentation to preserve viewport VOI LUT and allow calling from both set and update actions.
- Improved cine playback performance by minimizing unnecessary updates.
- Fixed resize listener in OHIFCornerstoneViewport to properly fire on DICOM SR load and added ready events for image rendered for testing purposes. Also adjusted scrollbar size to reflect the number of images.
- Added the ability to configure the max number of image sets per series returned for Amazon HealthImaging datasets. By default it is set to 300 as suggested by AWS to prevent delayed study list loading for datasets with very large series.
- Added support for dataset URLS that contain port numbers
- Added user documentation for essential DICOM metadata fields
- Added new warning messaging for unsupported inputs
- Added integration for AWS Marketplace billing
- Improved user experience when copying information from the studylist
- Improved browser memory detection and user warnings
- Fixed active measurement color for microscopy to be consistent with other measurements (Active measurement is green. Inactive is yellow)
- Fixed issue with microscopy point measurement tool not appearing on image as expected
- Relocated Microscopy scale so that is is not obstructed by the help icon
- Resolved rounding error issue in the onscreen display of some calibrated measurements
- Updated indications for use to reflect the latest updates to the text
- Fixed issue where Cornerstone3D displays inverted images when WL/WW is 0 or undefined
Known limitations:
- Saving measurements requires STOW endpoint which may not be supported by some DICOMWeb datasources
- Some datasources (ie Amazon HeathImaging) may not support all search queries and therefore search or filter on the study list will return no matches
- Not yet recommended for use on mobile devices
Known anomalies:
- PET SUV mode and MPR may not render correctly in Safari v17.1 on a Mac; these features will work best in Google Chrome.
