Comparing the performance of ultrasonic strain imaging algorithms

Three displacement estimation algorithms that can be used in ultrasonic strain estimation are introduced. Different displacement models are used in these algorithms with the intention to improve the spatial resolution and extract as much strain distribution information as possible from the recorded pre- and post-compression rf echo waveforms. The performance of these algorithms is compared by means of measuring their modulation transfer function (MTF) and generalized noise equivalent quanta (NEQ).
