Methods and systems for ultrasonic imaging
First Claim
1. A method for ultrasonic imaging by an ultrasonic imaging system that comprises a transducer, an echo signal processor and a display device, the method comprising:
- emitting, via the transducer, a sequence of ultrasonic pulses at a target to be detected, the sequence of ultrasonic pulses comprising Doppler pulses from which a Doppler image can be produced interleaved with B pulses from which a B-mode image can be produced;
receiving, via the transducer, ultrasonic echoes from the target to obtain echo signals, wherein the echo signals are Doppler pulse echo signals and B pulse echo signals;
processing the echo signals via the echo signal processor, wherein processing comprises;
processing the B pulse echo signals to obtain B-mode image signals, obtaining additional B-mode image signals by processing said Doppler pulse echo signals, and combining the B-mode image signals obtained by the B pulse echo signals with the additional B-mode image signals obtained by the Doppler pulse echo signals to obtain new B-mode image signals;
processing the Doppler pulse echo signals to obtain flow image signals, wherein the flow image signals are based on a velocity value for a specific position at first and second times,processing a portion of the Doppler pulse echo signals that are used to obtain the flow image signals to also obtain spectrum image signals based on a Doppler shift at or proximate to the specific position; and
displaying a representation of the new B-mode image signals, flow image signals, and spectrum image signals on the display device.
