Ultrasound Artifacts | Ultrasound Physics Course | Radiology Physics Course #25

[@radiologytutorials]

Thank you all for watching. At 3:04 I misspoke 😖 The diagrams here are correct. What I meant to say was, if speed of sound increases in the second medium the angle of transmission will be more than the angle of incidence. And visa versa. Apologies for that!

[@radiologytutorials]

If at all confused I explain it correctly in talk #7 of this series (refraction) 🙂

[@Naijascan]

Thank You sir❤❤❤❤

[@rubyamir5245]

😂😂😂😂… I had to go back to your video on refraction to digest this “new” concept… I wish I had seen your apology before 😂😂😂😂😂

[@rosalibruggemann5595]

I cannot begin to tell you how much these videos have helped me. Even though they are assumingly for human ultrasonography, the same concepts apply for veterinary, and it has been SUCH a huge help to have these videos as supplementary learning material for the course I am doing at the moment. You are a freaking rockstar, thank you! Your explanations make some relatively difficult concepts easy to understand and you have a gift for visualising concepts and making them relatable to the general ultrasound-studying public! Truly awesome videos, thank you so much!

[@drguruprasadn]

Wonderfully conceptualised and explained. You make ultrasound physics look so easy. Thank you

[@KelleyVanScoyk]

I am studying for my veterinary radiology preliminary board exam and these videos have been immensely helpful. Thank you for taking the time to make them!

[@radiologytutorials]

You're welcome! Hope the exam goes well. Veterinary radiologists are the best!

[@ClaireWhittaker-b6m]

Me too!!!

"Thank you so much for this amazing tutorial! Your explanations were clear and concise, and I learned so much from your lecture. Your knowledge and expertise in this subject were evident, and I appreciate all the effort you put into creating this tutorial. Keep up the fantastic work!"

Thank you Atiqullah. Appreciate you taking the time to write such a lovely comment. Warm regards from South Africa 🇿🇦

[@mohammedsaboor4461]

Simple, Informative and Brilliant. Hats-off. Thank you so much.

[@radiologytutorials]

Wow, thank you. I appreciate it!

[@hashemel-lakany286]

Is the Question bank subscription for life? Amazing content❤️❤️

[@radiologytutorials]

Lifetime access! All future updates etc will be available too. Thanks for your support Hashem

[@giggitygoo92]

Awesome videos! I think you may be misspeaking during the refraction explanation. Your explanations about the sound waves slowing down or speeding up seem to be backwards relative to the diagrams (c2>c1; c1>c2)

[@stellamakrigianni608]

Fantastic work!

[@colourless2843]

Thank you so so much！hope I get my license next January

[@radiologytutorials]

Awesome! I'm sure it's very much deserved!

[@nialladams4009]

Your videos are a godsend.

Thank you! Appreciate the support 🙂

excellent class ,me a fan of u

[@BenceMány]

great videos, thanks for them!

[@daniell9062]

But the enhancement artefact can also be due to "falsely" applied Time Gain Compensation no?

[@coleenjones7531]

Hello, thank you so much for your videos. please can you clear up the twinkling artifact? on radiopaedia, it says lower the PRF, but when you read the papers the website sites, they both say to increase the PRF?!? any help would be great

[@kemchobhenchod]

2:20 You forgot rule #1 of sound club, we do not talk about sound club

[@kazuya9696]

Thank you for the great video. I just have a question regarding Snell's law. You mentioned in the video that "if the speed of sound increases, we will get an angle of transmittance that is smaller than the angle of incidence" but the diagram seems to show otherwise. I've gone through the calculation via the formula and I think if the speed of sound increase in the 2nd medium, the angle should also increase. Pls let me know if there's a mistake in my understanding. Thank you

[@radiologytutorials]

Hello. Not sure I did say that. If I did, do you mind letting me know when in the video so I can highlight the mistake for others? You’re right angle of transmission is higher than incidence of speed increases.

@@radiologytutorials it's around 03:00 to 03:20

[@radiologytutorials]

@@kazuya9696thank you so much! I will pin a comment to the top to let people know. The diagrams are correct! I misspoke 😖😖

How do you explain pseudotumor and pseudocyst?

[@CalebChou-i2i]

Dr Michael, I am a dedicated fan of your Radiology Tutorials on KZbin and greatly appreciate the quality of your content. I am writing to seek your permission and guidance regarding a project I have in mind. I would like to translate and dub your ULTRASOUND PHYSICS series videos into Chinese. To make your invaluable educational content more accessible to Chinese-speaking students on Bilibili, a popular video-sharing platform in China. By providing Chinese voiceovers, I aim to bridge the language gap and facilitate their understanding of the complex concepts you explain so effectively. Please rest assured that I will respect your intellectual property rights and adhere to the following guidelines: 1. The translated videos will not be monetized on any platform, including Bilibili. 2. Proper attribution will be given to you as the original creator, both in the video description and within the video itself. 3.

If you have any concerns, suggestions, or specific instructions, I am more than willing to accommodate them. I eagerly await your response and look forward to the opportunity to share your exceptional work with a wider audience.

[@radiologytutorials]

Hi Caleb. Sorry for the delay. Keen to chat with you on Zoom. Will send you an email now. Let’s chat 🙂
