Abstract

Elasticity imaging is an emerging diagnostic modality whose development now is largely empirical. This paper outlines a framework for designing ultrasonic bioelasticity imaging systems based on a maximum-likelihood estimator of tissue motion. A principal goal for image formation is to maximize waveform coherence, which is to correctly match Fourier coefficients of the echo data recorded before deformation to those recorded after deformation. A crosstalk matrix is developed for strain imaging to obtain new insights into the physics of elasticity imaging, in particular resolution, and a simple figure of merit for evaluating system designs.
