32 Bringing CV and Robotics to the OR part of my work was to develop a means to get this ground truth evaluation to compare with our competitors. We’ve used the trackers our competitors use, and we’ve developed their algorithms. We don’t know if they’re exactly the same, but we have the same data. We can tell the orientation and position errors by comparing the algorithm registration with the ground truth registration. ” Ganymed Robotics has a prototype that works, but when developing a medical device, the road to market can be long and winding, incorporating regulatory approval and industrialization of the hardware and software. It currently anticipates completing all steps by the end of 2024. “ We’ve had four patents accepted for the vision part, ” Marion tells us. “ We’ve started the process with the FDA, but it’s differs from the surrounding soft tissue, like muscles and tendons. The algorithms have been tested on simulated and cadaver data with and without soft tissue to evaluate their robustness. The system provides information to help preserve the soft tissue surrounding the bones’ rigid structures. Ganymed collected data from 100 patients through a semi-quantitative evaluation to assess whether their algorithm performed optimally under operating roomconditions, considering factors such as bone exposure, lighting, anddraping , andensuredaccurate bone detection within the images in all cases. “ When I joined Ganymed, my initial focus was on making something that worked qualitatively, ” Marion recalls. “ As soon as the bone registration seemed to work, I wanted to know how well it worked.
