Take the equipment apart without touching a tube
Some concepts only click when you can move them. Drag a target angle, change an SID, swap a filter — and watch the thing you're being tested on actually respond.
Static figures make you memorize a picture
A labelled drawing in a textbook shows you one frozen state. So you learn what the diagram looks like, not how the parts relate — and when the exam changes one variable, there's nothing to reason from.
Every diagram is real geometry, not artwork
The shapes are computed from the actual trigonometry, so when you move a control the whole figure re-derives rather than swapping to a second drawing. If the geometry says the beam moves, the beam moves.
X-ray tube · anode angle
Drag it and the anode heel effect changes with the geometry.
How to use them
Open one and move something
Every diagram has controls for the variables the exam actually tests.
Watch what changes with it
The relationship is the lesson — that's the part questions are written around.
Meet it again in practice
Diagram questions reuse the exact same artwork, so nothing looks unfamiliar.
What you get
Diagrams and the question images that use them are generated from one shared geometry file, so the figure you studied and the figure you're tested on cannot drift apart. Every label is checked against the reference textbooks before it ships — and nothing anatomical is AI-generated.
Questions
What topics are covered?
Equipment and physics concepts where the relationship between variables is the hard part — x-ray tube construction and the exposure circuit today, with more added as they're built and verified.
Do the diagrams show up in questions?
Yes. A diagram question renders a static snapshot from the same geometry as the interactive version, so what you practise on is what you're tested on.
Do they work on a phone?
Yes — the controls are built for touch as well as mouse.
