Hero

What's New in This Release

DCE-MRI Support
Hero now includes a comprehensive suite of nodes for analyzing dynamic contrast-enhanced MRI (DCE-MRI) data. The package supports:
- Automatic detection of arterial input function (AIF) voxels
- Generation of standard AIFs
- Estimation of contrast agent (CA) concentration
- Pharmacokinetic (PK) modeling with Patlak, Tofts, and Extended Tofts models
  This enables flexible and quantitative perfusion analysis directly in your workflows.
New Node: Create Mosaic
The Create Mosaic node arranges slices or channels from a higher-dimensional image into a tiled layout along one plane, reducing the dimensionality by one.
For example, selecting the channel dimension in a 4D image (X, Y, Z, T) creates a 3D image where each slice displays all time points for that position. This is useful for inspecting all frames or slices at once.
Beta DICOM Reader & DICOM Export
A new, more robust DICOM reader is now available in beta. It improves compatibility with various DICOM formats and can be selected manually in the import nodes.
Additionally, Hero now supports exporting DICOM files from HeroStructs, allowing for seamless reintegration with external systems.

Include .img as DICOM file
Support added for .img files when importing DICOM files and folders.
Progress bar in “Load DICOM Folder”
A progress indicator has been added when loading large DICOM folders for improved user feedback.
“Save to Database” now exclusive by default
To avoid conflicts, the “Save to Database” setting is now exclusive, preventing multiple writes from happening simultaneously.
Renamed “Create Geometric Shape Mask” to “Create Mask”
The node title was updated for clarity and brevity in the workflow editor.
Custom Orientation Code in MPR Node
The Multi-Planar Reconstruction (MPR) node now includes support for custom orientation codes, enabling advanced control over image orientation handling.
Broadcasting in Combine Image Using Masks
The Combine Image Using Masks node now supports broadcasting across shapes and has improved output type handling.
Updated Batching Functionality
Several improvements made to batching logic, ensuring more consistent behavior across batch-based workflows.

Fixed spelling in “Split Image” node
Corrected a minor spelling issue in the node title.
Updated “Contour to Mask” subtitle
Now clearly reflects whether filter settings are being used in the conversion.
Improved node right-click behavior
Fixes and enhancements to the context menu on nodes for better usability.
Fixed node selection bugs
Resolved issues where nodes could not be selected correctly under certain conditions.

Python 3.10.9
This release includes support for Python version 3.10.9, enabling newer language features and broader package compatibility.
heropytools Compatibility
Fully compatible with heropytools version 1.3.3.
