Hello community,
What would be the best approach to create an interpolated volume (ideally a vtkImageData) from a stack of 2D non parallel slices (UltraSound images) ? Is it possible ? Here is a snapshot of all images …!

Thanks,

Freehand tracked ultrasound reconstruction is available in the VTK-based [PLUS toolkit](https://plustoolkit.github.io/). It is based on @dgobbi’s implementation (developed over a decade ago) but many added features added since then, such as GPU acceleration (using OpenCL), hole filling, automatic fan angle detection, various compounding options.
- GUI is available in 3D Slicer (in [SlicerIGT extension](http://www.slicerigt.org/wp/)). Both batch-mode and real-time volume reconstruction. These old video shows the concept (volume reconstruction is continuous now, you don’t need to wait 1-2 seconds for updates):
- Command-line interface is available [here](http://perk-software.cs.queensu.ca/plus/doc/nightly/user/ApplicationVolumeReconstructor.html)
- You can also link the algorithm directly into your application (it is available in [IGSIO library](https://github.com/IGSIO/IGSIO/tree/master/Source/VolumeReconstruction), so you don’t need to pull in the entire PLUS toolkit to use it).

Thank you !
We will try the IGSIO library, it seems to be the good solution for us 🙂
