In this video I explain how we can use the acronym FPADSCRYN to figure out relation between various parameters such as Frequency, Resolution, Sensitivity etc.

Studying about this acronym, with your questions at the end was actually pointed out something which I was not paying attention in the class or maybe instructor did not explained well. Thank you for giving your time.
Ducer A yields a higher frequency as well as resolution because the crystal being thinner flexes faster than the thicker crystal, the resolution is higher because the wave isnt traveling as far due to the lower penetration value
Thiner crystal will produce high frequency .ans is A Resolution means the power to identify the discontinuity situated nearby . So higher frequency can find more discontinuity, so answer is higher frequency will give better resolution .
Couldn't fit diameter in it. Well imagine a water hose with a large opening vs you pressing your thumb on the opening. Which case the water coming out will spread more? The thumb one right? So smaller the diameter larger the beam spread. Hope this helps.
@@NDTVideoLibrary Sorry for late answer... 3 years... I watched your video, started to use your acronym during UT course. On the exam Day in 2019, I wrote the acronym on my draft paper. You can have some confusion because of stress during exam. But this acronym will give you answers to many questions and calm you down. RESULTS: PASS. Thanks a lot.🙏🙏🙏

Would there be a way to convert this app for iPhones?
I really like acronyms, please give more in ultrasound.
Thanks for information!!
Very easy to remember, great job!!!
If possible make more videos like this.
Very informative!
Thanks, will do!
1, A Higher frequency gives better resolution
What a great Acronym - I'm going to use this from now on
hlo

Thanks. 4 years I can't understand this today I got
Haha. Good to hear that Philip. I am glad. Thank you for letting me know.
Thank you VERY MUCH for posting this video and offering up this acronym. I found it very helpful.
Thin crystal produces high frequency.
High frequency probes give better resolution..
Thanks this is super practical:)
Thank you for this video
thanks you so much for this trick
You are welcome!
Ducer A yields a higher frequency as well as resolution because the crystal being thinner flexes faster than the thicker crystal, the resolution is higher because the wave isnt traveling as far due to the lower penetration value
Jeremy Medlock, your explanation is spot on!!
Thanks
Cool
A gives high Frequency as well better Resolution.
A is answer, thanks for your trick
You are welcome Gogul Prasath
I would like to choose NDT as my career....any suggestions??
A gives high frequency and it’s frequency will give high resolution since it has thinner crystal
1.A (thin crystal) gives more frequency
2.A(high frequency gives better resulution)
Perfect
Thiner crystal will produce high frequency .ans is A
Resolution means the power to identify the discontinuity situated nearby . So higher frequency can find more discontinuity, so answer is higher frequency will give better resolution .
Element "A" produces sound with higher frequency ,it also provides better resolution !!
Parham Radmanesh , that's correct!
Very clever acronym , thanks a lot for sharing !! Looking forward to more informative videos !!
Thank you. And sure, if you have any suggestions on topics for such videos, let me know on pratik.9821@gmail.com
Low crystal thickness give high frequency
High frequency High resolution and sensitivity
Perfect!
This reminds me of FPADSCRAD from my days in RT. I hated that method.
The thinner the crystal gives a higher frequency, better resolution, greater sensativity
small crystal will gives a high frequency.
High F will gives a better resolution.
low crystel tthicnesss Hiigh HZ, frequenncy directly proportional to resulation.
suresh chowdary yes, you are right!
Neeto !
A = crystal thinner
High frequncy
High resolution
A higher frequency
A better resolution
1. Low thickness prob
2. High frequency
what about diameter?
Couldn't fit diameter in it. Well imagine a water hose with a large opening vs you pressing your thumb on the opening. Which case the water coming out will spread more? The thumb one right? So smaller the diameter larger the beam spread. Hope this helps.
Imagine mobile flash light (small dia) gives high beam divergence, big torch gives small beam divergence

For both questions answers is a
Higher frequency better resolution
Thanks
