摘要：
Systems and methods for designing and fabricating three-dimensional objects with precisely computed material compositions for use in enhancing electromagnetic fields for magnetic resonance imaging (“MRI”) are provided. As examples, the fabricated object can be designed to reduce magnetic field inhomogeneities in the main magnetic field of an MRI system, or to reduce inhomogeneities in a transmit radio frequency (“RF”) field (i.e., a B1 field). As examples, the object can be a shim； a housing or other part of an RF coil； a medical device, such as a surgical implant； or component used in a medical device, such as a housing for an implantable medical device.
