Abstract :
Phase unwrapping problem in magnetic resonance electrical impedance tomography is discussed in this paper. We use the modified model-based phase unwrapping method to unwrap the wrapped phase images and its performance is evaluated through the experimental results. Several phase unwrapping methods are compared.
