MAGNETIC RESONANCE SAFETY OFFICER (MRSO) - RADIO FREQUENCY - MODULE 4 1. Purpose of RF (B1) field: excite hydrogen protons 2. RF energy is absorbed by tissues: within the volume of the RF transmit coil. This is a thermogenic process. 3. Thermogenic process: Results in production of heat. Ex: RF energy absorption 4. MRI local and whole-body tissue heating is due to: magnetic induction 5. Types of RF coil designs: -linearly polarized -circularly polarized (quadrature) 6. Function of coils: ...

TMS - technique for inducing virtual lesions or temporarily excite neurons Principles - rapidly changing magnetic fields => induction of electric current Method - - a coil is placed near the participant's head - very brief, very large pulse of current is run through - induction of strong, transient magnetic field - transient magnetic field induces current in nearby conductors (e.g. neurons in the brain) Can Cause - - activation: response of peripheral muscles after stimulation - inhib...
