Adaptive optimisation method for ultrasound measurement signals

摘要

The method comprises the steps of controlling an ultrasound transducer with a signal (sk(n)) to generate an ultrasound wave and to receive a reflection. An error value (gamma) is formed for use-specific optimisation of an ultrasound measurement signal (ek(n)). The signal shape of the ultrasound signal is changed by step-wise variation of the shape of the transmission signal (sk(n)). The ultrasound signal is radiated, received, and a new error signal is formed. This process is repeated until the error signal is minimised. The ultrasound signal with a minimised error signal represents the optimised signal. A microprocessor is provided for adaptive optimisation.
