Not sure if the question banks are for you?
If you're here, you're likely studying for a radiology physics exam. I've spent the last few months collating past papers from multiple different countries selecting the most commonly asked questions. You'll be surprised how often questions repeat themselves!
The types of questions asked in FRCR, RANZCR AIT, ARRT, FC Rad Diag (SA), ABR qualifying Core Physics and MICR part 1 are surprisingly similar and the key concepts remain the same throughout. I've taken the most high-yield questions and answered them in video format so that I can take you through why certain answers are correct and others are not.
Happy studying,
Michael

Wow, thank you so much! I can't believe I made it to the last tutorial, I appreciate your time putting this all together, it was phenomenal. I'm working in industrial ultrasound and this was fantastic. Cheers.

Thanks so much! I'm so glad and grateful that I made it through all the lectures. Especially the last slide on bioeffects and Intensities . I work in medical physics healthcare.

I'm a little confused about the relationship between the spatial average and the beam uniformity ratio. You said that the spatial average is equal to the spatial peak divided by the beam uniformity ratio, and that the beam uniformity ratio is the spatial peak divided by the spatial average. It seems like there's something kind of circular about that. What I mean is that in order to determine what the spatial average is, one would first need to know what the beam uniformity ratio is, but in order to determine what the beam uniformity ratio is, one would already need to know what the spatial average is, since the the spatial average is the denominator of that fraction. So therefore, in order to calculate the spatial average one would already have to know what the spatial average is. That can't be right. What am I missing? This was an excellent course by the way. I look forward to testing my knowledge with your ultrasound question bank.

Very informative, thank you! Would you have any comments on the safety of using Ultrasound skin tightening devices like Medicube Deep Shot and L & L Skin? These devices claim to heat collagen in the deep skin layer to stimulate more collagen production. Do you see long term negative effects on the body? I'm concerned that those devices could cause cavitation which could lead to cell damage from the free radicals created by the cavitation but I'm not sure if that would be considered a long term effect. Thank you for your time!

Please add a lecture on how to calculate resolution in ultrasound using phantoms and Perspex blocks…

@dhilshadjamal2255 7 месяцев назад

watched all 26 episodes and that was really enlightening and helpful. thank you for your time and keep rocking

thanks alot for making these videos. 👏👏👏🙏

@davidecappelli9961 6 месяцев назад

Very clear and very well summarized! 👍

@djalilaberbara3464 Год назад

Thank you so much for your efforts! Im an ENT specialist who wanted to understand the fondamentals of ultrasound. Your lectures are truely amazing!

@radiologytutorials Год назад

Thank you Djalila 🙏🏻 ENT is such an excellent specialty!

@mitchelwhorton4492 Год назад

really quality lectures - studying for radiology core exam currently. Are you also planning to cover nuclear physics in the future?

@radiologytutorials Год назад

Thank you Mitchel. Plan is do do MRI then CT then nuclear. Who knows how long it will take 😅 hope the studying is going well!

@sebifix 11 месяцев назад

Hey, thank you so much for all the effort you put in your videos! They really helped me a lot!!! Keep on the good work. If you find the time to answer, I would love to know which programs/software you are using to do your graphics? Thank you in advance!

@radiologytutorials 10 месяцев назад

Hi 👋🏼 sorry for the delay. I use PowerPoint for everything 🙂 in the MRI module I have been making 3D diagrams and for this I use a free program called tinkercad. Hope this helps!

POCUS will definitely change the approach of clinical medicine at all levels, primary to tertiary level care. How then it’s so imperative, according to me, that every clinician master this skill.( ALARA always considered). So wish was introduced to this as an undergraduate… Thank you Dr, your explanations are so comphrensive🙏🏽💕💖

@pietndala7394 11 месяцев назад

I follow also Dr Mark Yousef sono lectures on ultrasound instrumentation which solidifies the entire ultrasound background knowledge. I’m grateful for both selfless clinicians who assist us advance our skill set

@radiologytutorials 10 месяцев назад

I will check out Dr Yousef. Thank you for letting me know about him 🙂
