Express coil consists of three parts:
1) HNA, functionally similar to NV coil;
2) PA, functionally similar to CTL coil;
3) AA, functionally similar to 8Ch body array or 4Ch torso coil.
HNA and AA are removable coils that connected to Port A in LPCA. PA coil is embedded in
the cradle of the fixed table, which can be moved in and out of the magnet bore with the
cradle. The interface board of PA coil located on the bottom of the cradle. Two cables
always connect the PA interface board and Mega Switch by Convert Board located under
the foot pedal cover, which one cable is for receiving RF signal from PA coil and Multicoil
bias, and another cable is for providing DC power for PA coil.
Because it is a little difficult and time consuming to disassemble the cradle, and handling PA
coil needs great care, for easy, safe and quick reason, the cradle and built-in PA coil
composed one FRU. Two person need when replacement because the weight is more than
16KG.
