Deconvolution of medical ultrasound data with consideration of the pressure field, the excitation pulse and focussing

Medical ultrasound data suffers from blur caused by the volume expansion of the pressure field of the mechanical wave. This blur is dependent on the used excitation signal and focussing of the ultrasonic wave and can therefore be examined and manipulated to compute a set of better parameters for deconvolution on the data in order to improve overall system resolution. Looking at the ultrasound transfer function we can focus on the examination of the "point spread function" and ways to influence its size especially in the lateral and elevational direction. Furthermore the combination of several measurements from different directions is analyzed to compensate the worse elevational resolution with the lateral resolution of measurements from other directions.
