Patent ID: 7674228

Claim:
A method of producing an ultrasound image, comprising: generating ultrasound; transmitting N pulses of the ultrasound into a subject at a first location, wherein a first reference point of an ECG signal taken from the subject triggers the ultrasound transmission; receiving N pulses of ultrasound reflected from the subject at the first location; transmitting N pulses of the ultrasound into the subject at a second location, wherein a second reference point of an ECG signal taken from the subject triggers the ultrasound transmission; receiving N pulses of ultrasound reflected from the subject at the second location; processing the N pulses of received ultrasound from the first location to form N′ first ultrasound color traces and processing the N pulses of received ultrasound from the second location to form N′ second ultrasound color traces, wherein N′ is less than or equal to N−1; incrementally repeating from n=1 to N′ reconstructing the N′ first ultrasound color traces and N′ second ultrasound color traces into N′ image frames, wherein each image frame is comprised of a first line corresponding to the nth first ultrasound color trace and a second line corresponding to the nth second ultrasound trace.
