“ Find the right balance between professional and family life… ” 16 Application: EOS Imaging Marie Meynadier is the CEO of EOS Imaging, a company that develops advanced imaging and image-based solutions for musculoskeletal pathologies and orthopedic surgical care. Computer Vision News Application EOS Imaging improves patient treatment through safe imaging by reducing radiation while still providing complete and precise image-based data and surgical planning, based on relevant 3D patient anatomies. Millions of patients suffer from musculoskeletal conditions . About 2% of teenagers do not have normal bone growth. In addition, as a person ages, they may experience bone degeneracy that develops pathologies in the musculoskeletal system. Treatment of those patients involves orthopedic surgery such as hip or knee replacement or spinal surgery. For the surgeon to plan and diagnose the surgery, they need to have an image of the patient’s bones. This requires the repeated use of X-rays to obtain highly valuable medical images. Prior to the innovation by EOS, two modalities existed based on X-rays. Invented in the late 19 th century, the planar X-ray remains the #1 modality used in bone imaging. However, this type of X-ray emits a high level of radiation . In addition, it can only produce a flat, projection image and doesn’t give a view of the bones in 3D. For example, if a person’s femur or neck goes forward or backward 20 degrees, a planar radiograph does not detect the difference. In order to acquire 3D data, doctors use a CT scan which appear in 3D and can capture the entire body. However, the patient must lay down in a position which precludes some information about bone organization in the skeleton, a key point in treatment of orthopedic surgery. Patients also get an even higher dose of radiation during a CT scan. EOS Imaging provides the solution, putting together a number of technologies to solve these issues . One is an X-ray detection, based on a technology developed by Nobel Prize in physics Georges Charpak. It allows EOS to take X-rays with a very low dose of radiation while still capturing the entire body. They combine a linear scan of the patient from head to toe. That solves the issues of size and dose.
