Abstract
Osteoarthritis (OA) is the most common form of arthritis and is characterized by inflammation of the synovium which plays a role in pain production and cartilage degradation. To visualize and quantify the inflammation, our lab has developed a 3D US musculoskeletal imaging system, equipped with a mechatronic counterbalanced arm that supports a 3D US-based linear motorized scanner and allows tracking of the 3D US scanner. The work being presented describes the validation of the system’s tracking and image fusion properties, as well as a demonstration of the system’s utility for imaging large joints, such as the knee. The validation was conducted using agar phantoms containing inclusions for spatial and volumetric validation. Results indicated accurate and precise tracking and fusion, making the system a promising tool for quantitative monitoring of soft-tissue changes in joints afflicted with musculoskeletal pathologies.

Clara Duquette-Evans is a graduate student at the University of Western Ontario, in London, Ontario, Canada. She completed her undergraduate degree with a double major in Medical Biophysics and Physiology at Western and is pursuing a master’s in biomedical engineering. She is currently working at the Robarts Research Institute, in Dr. Aaron Fenster’s medical imaging lab. Her research explores the clinical use of 3-dimensional ultrasound for musculoskeletal pathologies and is at the moment focused on inflammatory changes occurring in the thumb and wrist as a result of osteoarthritis.
