method, storage medium, and system for monitoring clairseme imaging by acoustic radiation force pulse

摘要

The sparse tracking (30) used in acoustic radiation force impulse imaging. Tracking (30) is sparse. Displacements are measured (26) only once or sometimes for each reception line. Although this may result in insufficient information to determine the displacement phase shift and / or the maximum displacement over time, resulting displacement samples for different reception lines as a function of time can be used together to estimate ( 34) the speed, such as by a Transform (40) of Radon. The estimate may be less prone to noise due to the sparse nature of the displacement samples using compression detection (36).
