It is now possible to load and apply a pre-trained neural network in any workflow. We currently support .onnx and .pb formats for the frozen, stand-alone networks.
Multidimensional diffusion analysis using dVIEWR
The dVIEWR license contains an extensive collection of functionality for analysing multidimensional diffusion images using the QTI and Full-DTD models that has been added in collaboration with Random Walk Imaging.
- Added visualization node.
- Added support for simple ROI statistics in the visualizer.
- Adding a ROI to a locked viewport will visualize that ROI in other locked viewports.
- Vector images are now visualized as RGB in the visualizer.
- It's now possible to drag images from databases and viewport items to the viewport directly.
- Added colormap settings editor.
DICOM RT Structure Features
- Added node struct apply transform.
- Added image iso to struct node.
- Added structure merge node.
- Added structure decimation node to reduce the number of points in a structure.
- Added simple count variable $i to struct renamer.
- Added support for MHD images in the database.
- Added support for NIfTI in MICE databases.
- Added NIfTI import control.
- Added support for importing images to MICE databases from workflows.
- Added support for tagging in MICE and MIQA databases.
- Datasets can now be linked in the database from workflows.
- Added default pixel value to transformix processor.
- Added support for multiple initial transforms in transformix parameters.
- Added support for frame by frame elastix registrations.
- Added default pixel value to pre-defined registrations.
Plot and Data Table Features
