In one example, a magnetic resonance imaging (“MRI”) system comprises a magnetic resonance imaging assembly defining a gap region, a transmitting coil proximate the gap region, and at least one test coil separate from the transmitting coil. The at least one coil is mechanically coupled to the assembly during imaging and the at least one test coil is selectively electrically coupled to the assembly to collect test data. The at least one coil may be coupled to a test fixture coupled to the assembly. The test fixture may be deployable from a first position to a second position for collection of test data. The at least one coil may comprise a first test coil and a second test coil. Methods are also disclosed.
