In breast imaging, the image quality is severely degraded by susceptibility-induced B0 inhomogeneities. Here, we apply the novel integrated parallel reception, excitation, and shimming (iPRES) technology to enable simultaneous image acquisition and localized B0 shimming of the breasts with the same coil array. Proof-of-concept in vivo experiments with only four iPRES(1) breast coil elements already show up to 43.3% reduction in B0 root-mean-square error with no SNR compromise. Simulations show that the shimming can be further improved by implementing more complex iPRES(N) geometries with N smaller shim loops per RF coil element.
