Zone II has a magnetic field density of - 5-10 Gauss Who must be cleared to enter the Zone II MR environment by the Clinical director prior to scanning - subjects with relative contraindictations All unusual MR related incidents should be reported to - the Chief Technologist and the Clinical Director of the BIC What are the components of the imaging process - 1. main magnetic field (static mag field) 2. time varying mag fields (mag field gradients and RF fields) 3. radio freq fields (RF coils) What is the FDA limit for static magnetic field strength for clinical imaging - 3T What is the fringe field - the stray magnetic field outside of the bore of the magnet what is the magneto dynamic effect - this is produced when a conductive fluid (blood) moves across mag field (proportional to the strength of the mag field
