I know it's been a long time, but I was just curious; how did your class go?

Спасибо, отличные лекции по узд и допплерометрии, жаль нет на русском

what is the operating frequency of the transducer?

@SIMTICS 4 года назад

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/

undetectable doppler effect on that ambulance sound example in the video

@SIMTICS 2 года назад

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.

@pb5640 Год назад

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.

@SIMTICS Год назад

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 🥲

@SIMTICS Год назад

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.
