MRI is a fascinating and pervasive technology that will touch most of our lives. Despite this, its workings are unknown amongst the general public. The aim of this workshop is to demystify MRI through a creative activity that relates directly to the physics of how they work. Part I: Talking (~10 mins): MRI at its most basic relies on the use of familiar machines: radio, loudspeakers, computers, electromagnets and can be simply explained by analogy with audio spectrograms. Phase plane graphs are used by MRI scientists to diagram what happens to the magnetic compass arrow of human tissue. Part II: Drawing (~25 mins): Phase plane graphs is the repeated application of three rules which can be done using pen and paper. These rules are taught, demonstrated and then participants take it away! Part III: Discussing (~20 mins): Once/whilst participants have produced their own graphs, we talk about how to interpret them and relate them to MRI science. Most importantly, we relate what they have drawn to what they might experience (the techno music) when they have MRI scans themselves. Each participant will get to leave with the diagram they have created, and a factsheet summarising how it works, and what the sounds mean next time they have an MRI scan. My background is as a physicist specialising in MRI research. I will season the talk with images (of myself) from my work, and anecdotes about some of the silly things I've done along the way.
