These pressure changes can be represented graphically. The amplitude of the graph corresponds to pressure. The power of the wave is proportional to amplitude squared. Power is measured in Watts. This power spread over an area is what is known as intensity. Intensity changes (such as increasing gain or attenuation in tissue) can be described using the decibel scale. We can also describe spatial and temporal intensities within a beam. ========================= SIGN UP TO MY MONTHLY EMAIL NEWSLETTER 👉 https://bit.ly/3ruLh3d 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 #radiology #radres #FOAMrad #FOAMed
