ABSTRACT:
A head or body coil assembly for picking up signals in an MRI system is provided. It includes a thin band of conductive material which surrounds the specimen having a thickness comparable to the skin depth at the frequency of the spin echo signals of the MRI system but being transparent to gradient waveform frequencies. The thin band is in the form of a cylinder which acts as a flux tube for the RF signals to automatically provide for a homogeneous magnetic field.
