A medical image registration method is proposed by using Scale Invariant Feature Transform (SIFT) algorithm and edge points matching. First, the corresponding feature point pairs between the reference image and the float image are established by using the SIFT algorithm, and the preliminary registration result is obtained by estimating the transformation parameters. Then, the edge points of the preliminary registration result image and the reference image are extracted respectively, and the coherent point drift (CPD) algorithm is used to register these two points set. Finally the accurate registration result is obtained. The experimental results show that this method can achieve accurate registration result in complicated deformation of medical images.

The effect of Pb excess on the crystallization and ferroelectric properties in Pb(Zr0.3Ti0.7)O3 (PZT) thin films has been investigated. Owning to atomic interdiffusion and volatilization during heat treatment, the Pb loss has an impact on PZT stoichiometric composition, perovskite structure, and ferroelectric properties. The electrical characterization shows that the polarization-voltage (P-V) hysteresis loop is closely correlated with the appropriate Pb content and frequency. With the aid of the Ishibashi's power law model, we extract the frequency coefficient of the model dependence of the Pb excess.
