Abstract:
1. A system for ultrasonic imaging, comprising: a signal generator unit for generating at least two out-of-phase pulses, wherein the signal generator unit convolves at least two out-of-phase sine waves with an envelope function to produce the at least two out-of-phase pulses, and wherein the at least two out-of-phase sine waves are modulated in a way to produce a chirped Gaussian pulse width modulated waveform; a signal transmitter unit coupled to the signal generator unit for transmitting the at least two out-of-phase pulses into media of interest; a receiver and raw data averager unit for receiving the at least two out-of-phase pulses modified by the media of interest, the receiver and raw data averager unit providing a point-by-point arithmetic average of the received at least two out-of-phase pulses modified by the media of interest; and a data processing unit coupled to the receiver and raw data averager unit, the data processing unit constructing an area of acoustic image based on the point-by-point arithmetic average provided by the receiver and raw data averager unit.
