I feel like I'm getting a physics lesson from Tom Hollands Peter Parker

😂 hoping for some superhuman skills round about now!

Thank you, these videos are so helpful for revision for my upcoming exams :) Don't know if it's already on your radar but a video on radioactive decay would be very helpful if you ever have the time

[@radiologytutorials]

Thank you Kerry. Yes 🙌🏼 it’s on the radar but will only be after the whole of ultrasound/MRI and CT 😣 I suspect your exam will be done by then!

[@kerryswales8135]

@@radiologytutorials Thank You! Yes they may well be but I still have another 2 years to go after this one, I'm sure it's something that will come up again!

Superb presentation, very nicely presented 🎁

Doubt : Inherent filtration is increased if beryllium instead of glass is used in tube window? T or F

[@otakuguy0054]

Thank you, sir, for making these videos. I'm a student starting the summer semester labs for the radiologic technologist program. I have a question regarding added filtrations: WHEN would added filtrations be used for an exam?

[@ankitajadhav2116]

Thank you, Sir. Can you please make more videos on CT Radioanatomy?

Hi senior Michael I've got a question hoping to find an answer. What is the impact of filtration on image contrast? Some books like Oxford says it worsens image quality because of beam hardening! Another researches says it improves image contrast because of removal of lower energy photon that contribute to image noise! So I got confused! Could you please clarify it?!

[@radiologytutorials]

Hi 👋 great question. It’s not a straight forward increase/decrease question. It very much depends on the primary beam energy, filter type and thickness, tissue type, thickness etc. As a general rule of thumb in diagnostic energy ranges, increasing kVp will reduce image contrast. Filtration, as you’ve said does this through beam hardening. If asked in an exam (MCQ) and given no other information, I would say filtration reduces contrast. Important to remember that contrast does not equal image quality and high contrast is not always better. Hope that help a little

[@abdovitamins6331]

@@radiologytutorials i also tend to choose this, filtration degrades image contrast. Thanks a lot 🙏

Thanks!

Is filtration and half value layer similar?

[@dorusmaassen1881]

verry clear thankyou!
