a Qualitative comparison with close-up views for two representative cases. The first case is with acceleration rate of 2×. The second case is with acceleration rate of 3×. More visual comparisons can be found in Supplementary Fig. 2–8; b Quantitative comparison for different organs with acceleration rates of 1.5×, 2×, and 3× in terms of PSNR, SSIM, and LPIPS. Acceleration is achieved by avoiding averaging of multiple noisy acquisitions.
