Learn MRI by running the physics, not memorizing it.
The real simulation engine runs client-side. Drag TR, TE and the flip angle and watch the contrast recompute on an actual brain slice, pixel by pixel, in real time.
Four ways in
Start where it suits you. Everything runs on the same real engine, so what you learn in one place holds true in the next.
Simulator
Sweep TR, TE, flip and TI, switch sequences and anatomy, and watch k-space, the 3D reconstruction and quantitative maps update live.
Open the simulator →Protocol planning
A scanner-console workflow: pick an exam, prescribe each sequence on the three-plane scout, and acquire it one after another, like a real console.
Plan an exam →Quiz
Read-the-scan self-test: identify the sequence, weighting, pathology and perfusion maps by topic, with scored feedback and explanations.
Take the quiz → Guided · premiumGuided course
A structured curriculum with exclusive course material, inline lessons, a mock-exam mode and a searchable reference library, building toward the registry.
Explore the course →The real engine, not a diagram
These are computed, not clip-art: the Python engine simulates the signal, so every panel responds to the physics you set.

The guided course turns the simulator into a full curriculum: exclusive material, a timed mock-exam mode, and a searchable reference library, aligned to the ARRT MRI registry.
