Abstract: A radio frequency (RF) coil array includes a first coil section and a second coil section mechanically coupled to the first coil section. The first coil section includes a first row of a plurality of double asymmetric saddle coil pairs arranged in a left-right direction and a second row of a plurality of double asymmetric saddle coil pairs arranged in a left-right direction. The first row and the second row are arranged along a superior-inferior direction. The second coil section includes a plurality of loop coils arranged around at least a portion of a perimeter of the first coil section.

Abstract: A radio frequency (RF) coil array includes a plurality of RF coil sections arranged in a superior-inferior direction. Each RF coil section includes a plurality of asymmetric saddle coil pairs configured in an overlapping arrangement in a left-right direction. The plurality of asymmetric saddle coil pairs may include three asymmetric saddle coil pairs arranged in a left-right direction. The position of the asymmetric saddle coil pairs on the left and right may be shifted in the superior-inferior direction with respect to the middle asymmetric saddle coil pair. In an alternative configuration, each RF coil section includes a first loop coil, an asymmetric saddle coil pair and a second loop coil arranged in a left-right direction.

Abstract: Localized magnetic fields are measured at frequencies into the microwave (GHz) regime using a conductive loop that is integrated on a vibratable member, such as a cantilever. Driving an alternating current at a first high frequency through the loop produces a high frequency alternating magnetic dipole at the same frequency as the current, with the alternating magnetic dipole normal to and centered within the loop. The alternating magnetic dipole at the center of the loop mixes with a sampled alternating magnetic field at a second high frequency at the center of the loop, resulting in application of a mechanical force to the loop and vibratable member. The vibratable member vibrates when the difference between the frequency of the loop current and the frequency of the sampled alternating magnetic field equals the resonant frequency of the vibratable member.
