Patent ID: 8747321

Claim:
An ultrasound-based diagnostic medical imaging system, the system comprising: at least one transducer, the transducer configured to be placed near a tissue surface, the transducer comprising a piezoelectric crystal configured to produce ultrasound waves for transmission into the tissue surface and to receive ultrasound waves reflected from structures below the tissue surface; a modulator configured to be connected to the piezoelectric crystal, the modulator configured to generate an output signal by modulating an input signal according to a structured random permutation pulse compression sequence, the modulator further configured to transmit the output signal through the piezoelectric crystal; a data processing controller configured to be connected to the transducer, the data processing controller configured to receive the reflected ultrasound waves through the transducer, the data processing controller further configured to correlate the reflected ultrasound waves with the produced ultrasound waves; and an image generator configured to generate an image based on the correlation of the reflected sound waves with the produced ultrasound waves.
