The MAVRIC family of metal artifact suppression techniques produces B0 field maps as part of its unique reconstruction process. Here, we demonstrate a solution to the inverse problem of reconstructing an implant from its generated B0 perturbation. MAVRIC field maps are used to determine the composition and geometry of imaged implants. A sample case is demonstrated with hip fixation hardware. There are a variety of clinical applications for this use of by-products from MAVRIC metal artifact suppression sequences.
