A moving X-Ray Machine for research on joints and bones

Sitem-insel has inaugurated Europe’s inaugural Dynamic Imaging Center (DIC). This cutting-edge laboratory captures X-ray images of individuals in motion, presenting a groundbreaking approach to diagnosing ailments related to the musculoskeletal system.

While movement is integral to understanding the human musculoskeletal system, conventional computed tomography (CT) and magnetic resonance imaging (MRI) scans necessitate patients to remain still, posing challenges in diagnosing various musculoskeletal disorders such as osteoarthritis and back pain. The ability to obtain images of patients in motion would enhance the detection of these conditions. Currently, musculoskeletal disorders are primarily treated symptomatically, often with painkillers, and advanced stages may require joint replacement or surgical stiffening.

This state-of-the-art laboratory employs a split-belt treadmill where patients’ movements are simultaneously recorded using high-speed motion capture cameras, force sensors, muscle electromyography (EMG), and a customized high-speed dynamic biplanar radiographic imaging (DBRI) system. The DBRI system can capture X-ray videos at frame rates of up to 1000 images per second in each direction, providing precise three-dimensional measurements with sub-millimeter accuracy. This capability allows for the detection of even the subtlest rolling and sliding movements within the joints.

The DIC’s moving X-ray images are not intended to replace three-dimensional images from MRI and CT devices but to complement them. The combination of these images offers a comprehensive overview of joint movement, particularly when individuals are in motion. This innovative approach yields valuable insights into joint diseases, including osteoarthritis, and facilitates improved diagnostics and treatments for prevalent issues like back pain, affecting a significant portion of the Swiss population.
