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