Abstract:
A method of measuring properties of a solid test subject using ultrasound comprising the steps for:a) generating a wide-band signal having a coded varying frequency waveform of fixed but arbitrary duration such that when convolved with itself will produce an approximation of an ideal impulse response of an ultrasound system; b) storing a replica of the wide-band signal; c) applying the wide-band signal to an ultrasound transducer and directing the ultrasound generated by the transducer at the test subject; d) capturing a received signal being the ultrasound transmitted through or reflected from the test subject with an ultrasound transducer time referenced to the signal in step c); and e) convolving the replica and the received signal to form one or more synthetic impulse images of said solid test subject, whereby measurement of properties of the test subject may be enhanced.
