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/
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.
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.
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.
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

Doppler? More like "dope-ler", because this stuff is really cool!
thanks
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?
Hai it was a wonderful crispy video that almost explains everything at the same time keeping things simple. Thanks a lot
That's awesome and extremely simple to follow.
Thank you
Merci docteur
Helped a lot, thank you
Thank you for your feedback. We're happy you found it helpful.
Much appreciated.
what is the operating frequency of the transducer?

good clip n presentation

Thanks for the feedback. Will pass that on to our Content Team! 😀
undetectable doppler effect on that ambulance sound example in the video

Спасибо, отличные лекции по узд и допплерометрии, жаль нет на русском
very useful.. tnx :))
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.
