MRI Scan Math & Protocol Optimization Trainer

Step 1

Start in 🧩 Learn Mode 1 (Guided Formula Builder) if you are still learning which parameters belong in the numerator vs. denominator.
Move up to 🧠 Learn Mode 2 (Formula Selector) once you want to test your recall of the equations before plugging in numbers.
Use 📝 Learn Mode 3: Multiple Choice or ⌨️ Learn Mode 4: Numeric Free-Response for independent exam-style speed drills.
Infinite mode keeps the current drill and any flagged problems for later review in this browser. It does not keep a full question history. Completed drills remain graded after reload; Retry or changing Learn Mode starts a new attempt without removing previous scores.

Step 2

In the Formula Builder modes, drag parameter cards from the MRI Protocol Console (or simply click a card) to drop it into an empty formula slot. Click any filled slot to remove the card.
Watch out for extra console parameters! The practice parameter list includes values you don't need (e.g., Frequency Matrix or TE during a scan-time calculation).

Step 3

Whenever a parameter needs unit conversion (such as TR in ms needing ÷ 1000 for seconds, or FOV in cm needing × 10 for mm), use the interactive pill toggle inside the slot to convert it before evaluating.

Step 4

When you check an answer, the simulator compares it with modeled common errors (e.g., Used Frequency Matrix instead of Phase Matrix or Forgot √NSA scaling) and explains conditional trade-offs between Scan Time, Spatial Resolution, and SNR.
