K-Space Navigator
Navigate through k-space using gradients - just like an Etch-a-Sketch!
Gradient Echo Sequence
Here's what a real MRI sequence looks like:
How to use:
- Click "Initiate RF Pulse" to start the FID signal and enable gradient controls
- Hold gradient buttons to move through k-space:
- "+Gx" moves right, "-Gx" moves left
- "+Gy" moves up, "-Gy" moves down
- Hold multiple buttons for diagonal movement!
- Keyboard shortcuts: WASD keys for movement (W=up, A=left, S=down, D=right)
- Watch the timer - you have 15 seconds before the FID signal decays
- See the red dot fade as the signal weakens over time
- The trail shows your path through k-space - just like drawing with an Etch-a-Sketch!
