DISA: DIfferentiable Similarity Approximation for Universal Multimodal Registration

1 code implementation19 Jul 2023 Matteo Ronchetti, Wolfgang Wein, Nassir Navab, Oliver Zettinig, Raphael Prevost

Our method is several orders of magnitude faster than local patch-based metrics and can be directly applied in clinical settings by replacing the similarity measure with the proposed one.

Anatomy Image Registration

Global Multi-modal 2D/3D Registration via Local Descriptors Learning

no code implementations6 May 2022 Viktoria Markova, Matteo Ronchetti, Wolfgang Wein, Oliver Zettinig, Raphael Prevost

Multi-modal registration is a required step for many image-guided procedures, especially ultrasound-guided interventions that require anatomical context.

Generative Tomography Reconstruction

no code implementations26 Oct 2020 Matteo Ronchetti, Davide Bacciu

We propose an end-to-end differentiable architecture for tomography reconstruction that directly maps a noisy sinogram into a denoised reconstruction.

TorchRadon: Fast Differentiable Routines for Computed Tomography

1 code implementation29 Sep 2020 Matteo Ronchetti

The library is designed to help researchers working on CT problems to combine deep learning and model-based approaches.
