Abstract:
An ultrasound imaging method for forming an image of an object using signals reflected from the object after transmitting an ultrasound pulse to the object, comprising the steps of:(a) transmitting a first set of the ultrasound pulses to the object by applying voltages according to a first code of a pair of modified Golay codes to one or more transducers; (b) performing pulse compression on a first set of reflected signals of the first set of the ultrasound pulses reflected from the object; (c) transmitting a second set of the ultrasound pulses to the object by applying the voltages according to a second code of the pair of the modified Golay codes to said one or more transducers; (d) performing pulse compression on a second set of reflected signals of the second set of the ultrasound pulses reflected from the object; (e) adding the pulse compressed signals of the first and the second sets of the reflected signals; (f) producing a receive-focused signal by using the added signal to form the image of the object; and (g) displaying the image.
