    Abstract

    The goal of this work is to provide a quantitative comparison between ultrasound and mechanical techniques for measuring tissue elasticity. The biomechanical response of beef muscle and tissue mimicking gel to uniaxial compression are characterized with ultrasound derived stress-strain curves. Ultrasound estimates of the Young's modulus of elasticity for samples are computed from the slope of the initial linear region of sample stress-strain curves. Elasticity of tissue samples was independently determined from force-deformation measurements made with an Instron universal testing load cell device. Results from in vitro ultrasound elasticity measurements of beef muscle are presented. Ultrasonic elasticity measurements showed an overall 0.72 correlation with load cell measurements for tissue strains less than 2%. To our knowledge, these are the first reported comparisons between ultrasound tissue elasticity measurements and independent mechanical elasticity measurements.
