Abstract:
The anisotropic diffusion equations-Perona &Malik(P&M)equations are resorted to to decrease the Rician noise introduced into the diffusion weighted(DW)images.To evaluate the efficiency of the P&M equations(with different functions)in accounting for the Rician noise,many experiments are designed.The results acquired from both Monte Carlo simulation experiments and real data based experiments proves the better performance of the reciprocal function based P&M equation in denoising the DTI images.
