Computed Tomography slice interpolation in the longitudinal direction based on deep learning techniques: To reduce slice thickness or slice increment without dose increase

Fig 7

Comparison of linear interpolation, the proposed parallel U-net architecture, and the proposed organ-oriented method (all p < 0.01).

Vertical axis shows the absolute errors of the liver region in the reconstructed slices.
