Weight-Bearing C-arm Computed Tomography for the Early Diagnosis of Osteoarthritis

Osteoarthritis (OA) is the leading cause of functional decline and disability in aging populations. The causes and progression of OA, particularly in the early stages, remain poorly understood. Current OA imaging measures are insensitive to early changes, or are logistically challenging and limited by expense and long scan times. 


The overarching goal of this project is to develop a novel weight-bearing computed tomography (CT) imaging method to expand our understanding of the mechanical stresses that affect cartilage and meniscus health and to provide a quantitative measure of knee joint health. 


Therefore, patients are scanned in standing upright or squatting position. In contrast to acquisitions in supine position, patients are more likely to show involuntary motion which results in motion artifacts in the reconstructions decreasing the diagnostic image quality. Focus of current research is the development of novel motion correction approaches using surface cameras.
