Simulation on 2D microwave imaging of finger joint with a Newton iterative method

Osteoarthritis (OA) is one of the most common arthritic diseases that causes of disability. For most people arthritis pain and inflammation cannot be avoided as the body ages. Although x-ray radiography is the most widely accepted method for diagnosis of joint-related diseases, but its validity of detecting OA is limited due to its inability to resolve well between soft tissues of similar densities. In this paper, we present a simulation experiment on 2D microwave imaging of finger joint by using a Newton method-based finite element reconstruction algorithm. Simulation results show that a 2mm-thick finger joint can be quantitatively imaged based on its microwave property.
