This paper examines a phenomenon suspected of limiting the spatial resolution of ultrasound elastography, and pursues a technical development to reduce the error introduced by this phenomenon. Elastography determines tissue strain by mapping post-motion image data onto pre-motion image data. An error arises in this mapping due to the fact that spatial warping of image data implies a warping of both the tissue and the measurement system response. An approach to data processing is studied to compensate for this system response related error. Underlying principals are first examined in one dimension, followed by presentation of at three dimensional implementation, suitable for application to volumetric ultrasound data.
