摘要： An antenna apparatus for a radio frequency (RF) coil to transmit signals to and to receive signal from a subject in a magnetic resonance imaging (MRI) system includes a distal surface facing away from the subject, a proximal surface facing towards the subject, a high permittivity material (HPM) having a shape, and an antenna coupled to the HPM and positioned on the proximal surface such that the antenna is positioned between the HPM and the subject.

摘要： A magnetic resonance system is disclosed. The system includes a transceiver having a multichannel receiver and a multichannel transmitter, where each channel of the transmitter is configured for independent selection of frequency, phase, time, space, and magnitude, and each channel of the receiver is configured for independent selection of space, time, frequency, phase and gain. The system also includes a magnetic resonance coil having a plurality of current elements, with each element coupled in one to one relation with a channel of the receiver and a channel of the transmitter. The system further includes a processor coupled to the transceiver, such that the processor is configured to execute instructions to control a current in each element and to perform a non-linear algorithm to shim the coil.
