Notice of Removal: Investigating the impact of elevated acoustic output in B-mode harmonic imaging and harmonic motion tracking

Abstract

Harmonic imaging techniques are widely used in B-mode abdominal imaging and motion tracking in shear wave elasticity imaging (SWEI) to reduce clutter and improve data quality. Harmonic imaging can be both signal-to-noise (SNR) and penetration depth (PD) limited, resulting in decreased diagnostic utility. This work evaluates B-mode harmonic imaging and SWEI harmonic tracking data quality between imaging sequences using a Mechanical Index (MI) within the FDA guideline of 1.9 and an elevated MI (1.9 < MI < 2.6), to determine if there is clinical benefit in exceeding the current FDA guideline for MI in the context of hepatic imaging.
