Area of Science:

  • Medical Imaging
  • Physics of MRI

Background:

  • Magnetic Resonance Imaging (MRI) education requires understanding complex parameter interactions.
  • Traditional teaching methods may lack interactive visualization of MRI physics.

Purpose of the Study:

  • To introduce a novel, user-friendly electronic teaching aid for MRI.
  • To facilitate the understanding of signal intensity variations in MRI.

Main Methods:

  • Development of a handheld electronic device for MRI simulation.
  • Demonstration of pulse sequence parameter effects (TR, TE) on signal intensity.
  • Illustration of tissue parameter influences (T1, T2) on image contrast.

Main Results:

  • The device effectively visualizes the relationship between TR, TE, T1, T2, and signal intensity.
