Background, Motivation and Objective Ultrafast and 2D intracardiac blood flow imaging could enhance the diagnosis of congenital heart disorders in newborn patients since current clinical ultrasound modalities are hampered by aliasing, beam-to-flow angle dependency and low frame rates. Hence, we investigated, using in-vitro data and multiphysics simulations, how 2D speckle tracking (ST) might overcome these limitations when performed in a high frame rate setting realized by diverging waves.
