Phase images for detector frame rates from f = 0.08 kHz to f = 5 kHz: reconstructions (a) using a spatiotemporal constraint and (b) using the standard CDI algorithm; (c) the SSIM compares the reconstruction quality of standard CDI (dashed line) with the spatiotemporal constraint method (solid line), where the shaded region indicates the optimal range of experimental imaging rates [f_{\rm i}], delimited by twice the rotational critical sampling frequency [2f_{\rm c}(v_{\rm R}) ] = 0.667 kHz (lower axis intercept) and SNR = 1 (upper axis).
