Combining pulse compression and adaptive drive signal design to inverse filter the transducer system response and improve resolution in medical ultrasound.
An adaptive inverse filtering technique has been incorporated into a medical ultrasound B-scan scheme that used a linear frequency modulated pulse for imaging. Resolution improvement is demonstrated with imaging experiments on wire targets and tissue-mimicking phantoms.
