ABSTRACT:
A coil (36) includes coil elements (381, 382, . . . , 38n). The coil (36) can transmit radio frequency excitation pulses into an examination region (14) and/or receive responsive radio frequency pulses from the examination region (14). A compensation network (42) includes decoupling segments (98), which each has a selected electrical length at least of a quarter wavelength (λ/4) and is electrically coupled to an associated coil element (381, 382, . . . , 38n) and a reactive network (100). The compensation network (42) at least compensates coupling between the coil elements (381, 382, . . . , 38n).
