ARTORG wins MICCAI 2020 Cataract surgery challenge

Cataract surgery is the most frequent surgery worldwide with a rising tendency. This year’s international challenge on AuTomatic Activity Recognition for catarACT Surgery hosted by MICCAI 2020 aimed to push research in increased safety and efficiency of this intervention. On 4 October 2020, a team from the ARTORG Artificial Intelligence in Medical Imaging (AIMI) lab was ranked first among all challenge competitors with a method recognizing both surgical tools and activity from a microscope video stream.

The proposed approach trains a deep learning model to jointly recognize surgical tools and the activity from the surgical video stream (ARTORG Center, Artificial Intelligence in Medical Imaging)

With cataract interventions increasing, improvements in safety and efficiency of the surgery are active research topics. Examples include automated post-operative analysis, surgical training, and real-time decision support for which automated comprehension of surgical activities is an important part.

The method proposed by Michel Hayoz, Mathias Gallardo, Pablo Neila Marquez and Raphal Sznitman from the ARTORG AIMI lab together with Martin Zinkernagel, Ophthalmology Inselspital, takes the surgical video stream from the microscope and recognizes the surgical activity based on the current and past video frames. The team proposes to train a deep learning model to jointly recognize surgical tools and the activity in the scene. By exploiting the relationship between the two, the model achieved promising performance, winning the CATARACTS Workflow Challenge 2020 worth USD 1250.
