It is very important for correctionofdistortion of these images to find focus of infection fast and correctly and diagnose the cases quantitatively and qualitatively.
畸变的校正对于快速发现、准确定位病灶，定量、定性分析病情具有重要意义。

The method USES the model of radial nonlinear distortion with the symmetry of optical axis to obtain correction coefficients of the optical lens, and then corrects the distortion image.
