Thank you for your feedback! We are glad you found it useful.
even now, 7 years apart, it's really easy to understand! thank you so much, you did a really good job
Hai it was a wonderful crispy video that almost explains everything at the same time keeping things simple. Thanks a lot
Much appreciated.
thanks
Merci docteur
That's awesome and extremely simple to follow.
Thank you
good clip n presentation
Hi Peter, thanks so much for your feedback! We have 2 complete Ultrasound Physics e-learning modules on our website with detailed text, full-length videos, graphical models and quizzes.

TH-cam subscribers can get a 30% discount - please use coupon TH-cam30 during sign up. Thanks for your support! (You can also find us on Facebook, just search for simtics.healthcare )
Very useful for my Physics class. Thanks for posting!
I know it's been a long time, but I was just curious; how did your class go?
Helped a lot, thank you
Thank you for your feedback. We're happy you found it helpful.
Doppler? More like "dope-ler", because this stuff is really cool!
what is the operating frequency of the transducer?
Hi there. Transducer frequencies are typically 2-10 MHz, and you'd select an appropriate one according to the anatomical structures you want to obtain images for. You can learn more about this topic in our Ultrasound Physics modules www.simtics.com/shop/imaging/sonography/sonography-fundamentals/
very useful.. tnx :))
Спасибо, отличные лекции по узд и допплерометрии, жаль нет на русском
undetectable doppler effect on that ambulance sound example in the video
Hi, the sound pitch does change - can you not hear that? As the vehicle approaches, the siren's pitch sounds higher than when it is moving away from you.
lol you got it all right except for the siren example. In emergency services we call that siren mode “wail” it would’ve made that sound even if the ambulance wasn’t moving. Nice try. in the future use a train horn which is a constant pitch sound that will illustrate your example much, much better.
Thanks for the feedback. Will pass that on to our Content Team! 😀
Why do they use Blue and red the opposite of Blue and red shift 🥲
We don't know where it originally came from, but it's just the default on most machines - blue flows away and red flows toward the transducer. You can usually change the color settings on the ultrasound machine if you prefer to use different colors.
