Speed of sound in tissue, at 2:24 in the video, is not around 1040 m/s. It's in the range of 1450 to 1580 m/s depending on the tissue type. Ultrasound machine default speed assumed for soft tissue is 1540 m/s because it's a weighted average of what's most likely to be encountered in a scanning session.

Also be careful with BART for Doppler colors. The speed colorbar shown on US displays will tell you unambiguously if the flow is towards or away from the transducer by looking at the color AND the corresponding positive or negative sign for the speed value. Don't just assume BART gives the proper interpretation.

Awesome man...loved the lecture.only faced one problem...you talk so fast...I had to reduce the speed...but the lecture was awesome...will look the rest of the lectures now to learn what many teachers usually never talk about.... In indopak region, the teachers never teach you just so that no one can replace them.they will rob you off your money but you will get nothing at the end of 6 months unfortunately.... Once I mentioned the B mode and A mode modalities and the teacher got furious and he said there is no such thing like B mode or A mode. Now what to do with such a person. 90% of the echo reports formed at even the major hospitals in kpk, Pakistan are damn damn inaccurate.quackery is practiced at its worst but I refuse to practice any such quackery.... Let me amaze you now 😵 it takes atleast 20-30 min to perform one examination but here in my country it takes 2-3 mins only.... Now decide what kind of echo report would that be...thanks to KZbin that gave me teachers from around the world

I m too from Pakistan, Karachi . I take more than 20 minutes to complete one normal scan of heart but if there are abnormal findings it take more than 30 minutes and sometimes more than an hour. I work in tabba heart institute where we follow almost all international protocols to make sure the study should be perfect.
@anasuyamukherjee78723 жыл бұрын
Same situation in India too. U mention anything that your professor didn't mention while he/she was explaining something ,they take it all in their ego and humiliate you with unrelated things to make sure you never speak up again. Even though you literally have to beg, for them to take any form of class and even if they ever teach anything that comes down 'how to break a student's morale'. But, this is not the case for very senior professors though.
