I want to congratulate you on this incredible video lecture series and the service you are providing to students and professionals everywhere. In the coming years, our nation will continue to need educators like yourself that are keen seeing future generations prosper. Please continue this great work, as I join the American people in thanking you for making this world-class educational series free and accessible for everyone.

Hi sir, Your stated of Nyquist theorem (which read: We need to sample a returning doppler shift frequency at least twice within one wavelength). Coming from a signal processing background, I want to ask if that is the physical meaning of saying to reconstruct a signal you need to sample at least twice the sampling frequency.

12:48 Why does increasing the SPL narrow the bandwidth?
@BethelHealthBuilders7 ай бұрын
Would it be correct to say that by having at least two return signals in a wave cycle, the wave function can be fitted (this is a sine wave) and thus the frequency and amplitude can be derived. That is how I can understand the Nyquist limit.

Many thx for your excellent talks. I may not understand the active region of color doppler. Outside of the box we have the general 2D picture by merging A-lines with short pulses and SPL. However, in the active region we have 2 poeces of information: A-lines in 2D-constellation and color. Color indicates as you mentioned the doppler shift. For me it is not clear that in this region we use two different pulse waves to have the 2 distinct values? Or a longer PRP enables both of them: 1) Time and intensity show us the A lines woth brightness? 2) The longer SPL allows to have the doppler shift value and position? Is this the solution or two different methods are running in parallel? Thank ypu inadvance, Tamas

It’s a difficult one. Next week I’m releasing an MRI video on aliasing (also using the Nyquist limit) and I’ve made much better illustrations. Hopefully I will be able to show how we need to sample a frequency at least twice per wavelength in order to accurately measure that frequency.

huh? So is duplex equal to spectral doppler equal to pulse wave doppler equal to continuous wave doppler? Or can you clarify the terms in short sentences?: Power doppler, spectral doppler, color doppler, duplex, pulse wave doppler and continuous wave doppler?
@joestevenson556811 ай бұрын
Spectral Doppler is continuous or pulse wave Doppler. Power Doppler is colour Doppler but without direction information
