A Comprehensive Interpolation for Medical Slices Based on Combination of Linear and Matching Interpolation

In the process to obtain 3D reconstructed isotropic data volume for medical slices, a comprehensive interpolation for medical slices that combines matching interpolation with linear interpolation is proposed. This method solved the problem that linear interpolation tends to blur the boundaries in interpolated images, whereas matching interpolation is time-consuming. The simulation showed that the comprehensive interpolation method produced clearer boundaries than linear interpolation while it largely reduced data handling compared to matching interpolation.
