=========================

The characteristic curve describes the specific properties for a particular screen film. The responsiveness to X-ray exposure at the film itself determines the characteristic curve. Different screen films have different speeds as well as latitude values. Both of which we discuss here. I practice we don't chose these properties directly as they have been predetermined by the manufacturer.

=========================

*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

great effort.. thanks and I hope you could cover more of the medical imaging physics

@radiologytutorials Awesome, thanks a lot. These videos are as simplified as it gets, got a hang of the topic. Can you post a video on spotters and long & short case discussion which would be helpful for our practical exam. Thank you

Thx for the effort please keep posting

Question please...list 5 types of information obtainable from sensitometric curves

[Geri_kariba]

After shoulder does the curve slope down or does it just go exponentially towards infinity ?

[mariyamyumna]

Hello Sir,

Is there any change on the appearance of the x-ray film after the point of solarization?

[venkatraamudu]

Thank you 🙂
Can you please explain " latitude and contrast of a film are inversely related" through characteristic curves of film a and film b given in the book .

How does high exposure have less transmission?

such a soft tender voice! Feel like a baby in KG

High OD will appear bright or dark on image?
