Inverse Scatter Imaging

Many new techniques have been proposed for imaging the human body by the processing and manipulation of ultrasound data acquired from the scattering of wave fields incident on some region of interest.The plethora of methods are analysed here to show the following common features: (a) an underlying physical model which prescribes the diversity of interactions thought to be amenable to measurement".(1:) a data acquisition configuration that restricts the full complexity of interactions contributing to the measurements.and limits the impact of possible artefacts; (c) a computational model.which is essentially an approximation scheme for linking the measured data to the interaction parameters of the underlying physical model.This approach serves as a unifying basis for classifying the various quantitative scatter imaging methods.These statements are illuminated below by the explicit working of a few telling examples.
