Resources we love
This course gives you the physics and the hands-on tools. These trusted, free companions give you endless cases, deeper derivations, and safety references. Every lesson also links straight to the most relevant ones under “Keep exploring.”
We’re not affiliated with any of these — they’re simply the references we’d hand a new resident or technologist. Radiopaedia in particular is an outstanding, openly-edited companion to everything here.
