Summary

We were contacted by Nicolas Vuignier, a Swiss professional freeride skier, for the making of short 3D animations of freestyle jumps. To this aim, we spent a day at Crans-Montana to follow Nicolas on the slopes where we performed his motion capture using our Xsens motion capture suit. His body was also 3D scanned using body scanning technology and as a result the virtual skier was animated.

Multiparametric Imaging of ORL Tumors

Contouring for radiotherapy planning

Project Info

Start date:
January 2018

End date:
December 2020

Funding:
Swiss National Funds (SNF)

Coordinator:
HUG – Division of Radiology

Back

Summary

This project aimed to improve the image-based diagnosis and treatment of head and neck squamous cell carcinoma. Multiparametric imaging with morphological MRI, diffusion-weighted MRI (DW-MRI), dynamic contrast enhanced MRI (DCE-MRI) and PET may offer precise tumor and lymph node staging, improved risk stratification and effective management of patients with primary and recurrent head and neck cancer. Moreover, by combining multiparametric data, target volume delineation and biological dose painting for radiotherapy planning can be improved. The goal of this project was to improve tumor diagnosis and tailor therapeutic approaches in view of a personalized treatment strategy.

In this project, Artanim was in charge of 3D tumors reconstruction and participated in the development of an histologically validated computer-aided tumor model for the accurate contouring of gross tumor volume for radiotherapy planning.

Summary

VR-Together offers new ground-breaking virtual reality (VR) experiences based on social photorealistic immersive content. For this purpose, this project developed and assembled an end-to-end pipeline integrating state-of-the-art technologies and off-the-shelf components. The challenge of VR-Together was to create photorealistic truly social VR experiences in a cost effective manner. Immersive media production and delivery through innovative capture, encoding, delivery and rendering technologies. The project demonstrated the scalability of its approach for production and delivery of immersive content across 3 pilots. It introduced new methods for social VR evaluation and quantitative platform benchmarking for both live and interactive content production, thus providing production and delivery solutions with significant commercial value.

In this project, Artanim worked on content production for the 3 pilots combining VR and offline/real time motion capture and developed new tools for immersive media production. We also participated in the evaluation of the developed social VR experiences.

Summary

Altered scapulothoracic alignment may be a contributing pathoanatomic factor to the development of the B2 pattern of osteoarthritis. The purpose of this study was to use a patient-specific 3D measurement technique coupling medical imaging and optical motion capture to evaluate and compare scapulothoracic alignment in patients with B2 glenoids. The results of this study may improve our understanding of glenohumeral pathoanatomy and posterior glenoid erosion patterns, and assist with osteoarthritis prevention.

In this project, Artanim was responsible for dynamically simulating shoulders from kinematic data.

Summary

Magic Window is a choreographic piece in augmented reality (AR), created for the renovation of the Aula des Cèdres in Lausanne, Switzerland. Through screens of mobile phones or tablets, users can see the space of the Aula des Cèdres in direct but also virtual dancers embedded in the image and disseminated on the site.

For this piece, we created the 3D bodies of the dancers using body scanning technology, and we performed the motion capture and animation of the virtual dancers.
