From: Three-dimensional nanoscale reduced-angle ptycho-tomographic imaging with deep learning (RAPID)
Performance of RAPID under \(N_\theta =21\) acquisition within the range \(\theta = 140.8^\circ \). a, b Quantitative (PCC, MS-SSIM, BER, and DICE) comparison among approximant, RAPID, FBP, and SART. c–g Layer-wise visualization of the reconstruction results from different methods, including the golden standard reconstructed from \(N_\theta =349\) angles, Approximant, RAPID, FBP, and SART recovered from \(N_\theta =21\) angles. h PSD distribution in \(k_z\)-\(k_x\) plane of different methods. For \(k_z\)-\(k_y\) and \(k_x\)-\(k_y\) planes, refer to the Additional file 1: Fig. S4
