Abstract:
1. An ultrasound-based diagnostic medical imaging system, the system comprising: a transducer configured to be placed adjacent a tissue surface, the transducer comprising a piezoelectric crystal configured to produce ultrasound waves for transmission into the tissue surface, the transducer configured to receive ultrasound waves reflected from structures below the tissue surface and convert the reflected ultrasound waves into a digital received signal, wherein the transducer comprises an impulse response that represents characteristics of the transducer; a signal generator coupled to an input of the transducer, the signal generator configured to generate an initial signal based on the impulse response of the transducer, wherein the signal generator receives an indication of the impulse response of the transducer from the transducer, and wherein the signal generator generates the initial signal in a manner that reduces noise introduced by the transducer into the digital received signal when the transducer converts the reflected ultrasound waves into the digital received signal from a first level to a second level that is lower than the first level; a data processing engine coupled to the transducer, the data processing engine configured to receive the digital received signal from the transducer, the data processing engine further configured to correlate the digital received signal with the initial signal; and an image generator configured to generate an image based on the correlation of the digital received signal with the initial signal.
