Abstract

Aiming at the problem of low interlayer resolution in medical tomographic images, this paper proposed an interlayer super-resolution algorithm based on deformation estimation and motion compensation. The method aimed to enhance interlayer resolution by generating interslice images. Firstly, the algorithm employed U-Net for multi-scale feature extraction and fusion of two adjacent images. To handle the complex deformation of interlayer images, it estimated slice bidirectional deformation by utilizing a warping module based on adaptive collaboration of flows. Multi-scale information fusion module performed feature aggregation on pyramid feature layers, to compensate for the motion of the generated map. Finally, it employed a post-processing network to reduce pixel outliers. The results on two CT datasets show that the PSNR of the proposed algorithm reaches 35.59 dB and 30.76 dB, the output effectively restores image details. Comparative experiments with existing methods demonstrate the effectiveness of the proposed algorithm.
