New Features

AI Features

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.

Visualizer Features

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.

Database Features

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.

Registration Features

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

Added node for Creating Expressions on columns of data tables.
Added node to create a plot (Data to Curve) from the columns of data tables.

Miscelaneous new nodes and functionality

Added nodes CTD1, CTD2, CTD3.
Added node String Concatenate.
Added multiple quick processes.
Added slicewise metdata.
Added quick processes that can be used in the visualizer.
Added application layouts.
Added node to extract metadata string.
Added node to extract image name.
Added DTI Forward Model node.
Add a repeater quickly by pressing ALT+Left Click on a connection.
Added frame-wise and slice-wise settings to the Descriptive Statistics node.
Added node to assert Boolean, Double, String and Image data.
Added 4D support for multiple nodes.
Added quartile statistics for ROI.
Added support for mirror and wrap padding in the padding node.
Added Fast Marching node.

Changes

Visualizer Changes

Removed image sets from visualizer.
Layer order inversed in visualizer.
Histogram of RGB images now show the histogram of all three channels.

DICOM RT Structure Changes

Removed Struct Selector
Removed Struct Renderer
All struct related nodes now operate on collections of structs, no single struct is allowed.
Improved RT-Struct export.

Database Changes

Patient images are now grouped by study in the database control.

Registration Changes

Transformix and Elastix transformations can now handle initial transforms.
Inverting an Elastix transform can now handle initial transforms.
Elastix node now handles multiple moving images faster.

General Changes

Images now use a new metadata structure.
Updated the About form.
Deprecated Patch Based Denoising node, and replaced it with Bilateral Denoising.
PCA node now works in all dimensions.
All reshape nodes now support multiple image types (Masks, Complex, Float).
In the Chan Vese segmentation node, “Image” was changed to "Initial Guess" while “Initial Guess” was renamed to "Initial Level Set".
