Before harmonic imaging, our imaging transducers had major limitations when it came to obtaining high velocity gradients with continuous-waved (CW) Doppler. Two of the main restrictions included the ultrasound frequency (no ability to drop down to a lower frequency) and the large footprint of the...

Evaluating the aortic valve is a routine part of an echocardiogram. There are many methods we use to determine the structure and function of the valve, including 2D, color Doppler and a combination of pulsed & continuous-wave Doppler. With short examination times being a common challenge, it...
