This Crusher Coil has been designed to fit the commonly used 7T head-coils from a 16ch up to a 32 channel. It can be custom-made for any RF head-coil from 1,5 T to 9,4T.
It is a very thin design (<5mm) made to suppress extra cranial lipid signals. A DC current (up to 10A) can be switched into the coil, synchronised through a trigger line from the MR system, which causes a local dephasing of spins.
The coil can be positioned between the head and the RF head-coil, still providing space for a comfortable pillow.
