Spatial resolution in elasticity imaging with ultrasound

Abstract

We are exploring the resolution limits of ultrasonic strain imaging techniques by building tissue-mimicking gelatin resolution phantoms with various targets imbedded. Through acquiring scan data with applied compression, we compute the strain and study the visibility and separability of targets with different sizes and separations. Our preliminary results have shown that targets with 4.2 mm in diameter separated by 1.6 mm are easily seen.
