Abstract :
A new data processing technique, called the inversion algorithm, is described to produce an undistorted, high resolution and low noise image of tissue. The algorithm is a hybrid approach in which general wave diffraction theory is used to extrapolate the propagated part of the acoustic pressure field back to the transducer while a probabilistic method is used to estimate the acoustic propagation velocity
