Radiographic Exposure Factors: What You Need To Know!

Welcome to my first video. In this video I cover everything you need to know about exposure factors, what they are, how they work, and how you can manipulate them to produce the best possible images.
Knowing these fundamentals is what will give you the confidence to take on any X-ray examination in your day to day as a Radiographer, particularly when you're still learning as a student. I hope you find this useful.
The topics I cover in this video include: kVp, mAs, beam quality, beam quantity, 15% rule, signal to noise ratio (SNR), quantum mottle, exposure optimisation, effect of kVp and mAs on images, and adjusting these factors for the best X-ray.

WHO AM I:
I'm Sahand, a Lecturer and Radiographer (and now UA-camr?) in Sydney AUS. I received my PhD (Medicine and Health) this year in 2023 on breast cancer imaging and radiation dose. I'm a lifelong learner, forever curious about the day to day things, and I'm here to make videos and give you my own unique take on the concepts that you may need some extra help with.
