OrthoMRI High reflected power when running system check The reflected power in system check is the red trace and the forward power is the blue trace. The reflected power should be less than 20% of the blue trace and is typically almost flat. Place a 50 ohm dummy load at the output of the RFA (RF amplifier) The reflected power should be nearly flat. If the reflected power is flat with the dummy load connected directly on the output on the RFA, the problem is not the RFA. Suspect the tuning or matching board adjustment or RF cable to the magnet.
