Patent ID: 7691061

Claim:
An ultrasonic diagnostic apparatus comprising: at least one ultrasonic transducer configured to send an ultrasound signal to an object and receive a reflected signal from the object; an A/D converter connected to the at least one ultrasonic transducer and configured to convert the received reflected signal into a digital data; a data averaging processor connected to the A/D converter to receive the digital data and configured to store lines of said digital data and average the stored lines of said digital data before demodulation; a demodulator connected to the data averaging processor to receive averaged digital data produced by the data averaging processor and configured to demodulate the averaged digital data to produce demodulated digital data, the data averaging processor being positioned between the A/D converter and the demodulator; an image constructor configured to construct a constructed image from the demodulated digital data; and a display unit configured to display the constructed image constructed by the image constructor.
