The resonance frequency - Study guides, Class notes & Summaries

In MRI, substances respond to a specific radio frequency which is known as: - Resonance frequency The effects of main magnetic field inhomogeneities on the FID signal are corrected for in a Spin-echo sequence by applying a second radio-frequency pulse. The flip angle of this radio-frequency pulse is: - 180 degrees The components of the Gyro-magnetic ratio are: - Magnetic moment to angular momentum Which type of electromagnetic coils produce smaller magnetic field which allow spatial locali...
