=========================
The photoelectric effect results in X-ray attenuation within patient tissue. This results in a 'shadow' being cast on our X-ray detector and ultimately is the basis for anatomic detail within a radiograph. Here we will look at the mechanism responsible form the photoelectric effect, the factors that affect the likelihood of attenuation to occur and discuss the K edge.

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
