To generalize the Multimodal Intrinsic Speckle-Tracking (MIST) framework to accurately image rapidly varying, rotationally isotropic diffuse X-ray dark-field signals without assuming spatial uniformity.
Extended the deterministic MIST formalism derived from the paraxial Fokker-Planck equation to remove the assumption of slowly varying diffusive dark-field signals.
Reconstructed multimodal attenuation, refraction, and small-angle scattering signals across two test samples exhibiting distinct X-ray attenuation and scattering properties.
Evaluated output image quality against prior MIST implementations using signal-to-noise ratio, the naturalness image quality evaluator, and azimuthally averaged power spectra.
The generalized formalism successfully resolved fine sample microstructures with non-slowly-varying spatial statistics that previous MIST variants failed to capture.
Reconstructed diffusive dark-field signals demonstrated superior image quality across all metrics, providing higher signal-to-noise ratios, improved naturalness scores, and refined power-spectrum profiles compared to conventional slowly varying models.
