Uncertainty quantification for ultrasound image velocimetry

Ultrasound image velocimetry (UIV) is a non-invasive method with high temporal-spatial resolution for measuring flow velocity in opaque media, particularly in biomedical fields. Velocity measurement uncertainty propagates into pressure and shear estimates, which are critical diagnostic parameters. Despite its importance, no method currently quantifies UIV uncertainty due to complex error sources. This study proposes the generalized moment of correlation (GMC), which builds on the moment of corre
