Abstract:
The classic whole-body or head antennas for NMR imaging do not resonate properly at higher frequencies. The high-frequency antenna presented is constructed from segments of transmission lines and is treated as a distributed parameter system. It has an RF magnetic response similar to that of the classic saddle-shaped antenna, has low exposed impedance to avoid dielectric losses in the patient, and does not disturb the magnetic field gradients. The implementation of a whole-body antenna for 64 MHz is described and tested.
