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

Let's look at how field of view and frequency encoding gradient strength influence receiver bandwidth. We'll then review how receiver bandwidth determines the Nyquist limit and how we can use this to know the required sampling rate. Once we know the sampling rate we can work out the sampling time (dwell time) and ultimately calculate the amount of time we need to acquire enough samples to satisfy the x axis resolution we need.

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
