Adaptive interference filtering in acoustic radiation force based ultrasound imaging

摘要

For clutter reduction in ultrasound elastic imaging (42), the contribution of clutter to different frequency components (eg, transmission fundamental and propagation of the second harmonic generated) is different. Consequently, a difference in the (40) displacements determined in the various frequency bands is used to reduce the contribution of clutter to the displacements (41) used for the elasticity imaging (42).
