US Patent 7551954 Magnetic resonance imaging with adjustable fixture apparatus

A fixture such as a local receiver coil is secured to the patient support of a magnetic resonance imaging system so that the fixture remains in position relative to the support even when the support is in a vertical orientation. The positioning apparatus is arranged to allow adjustment of the fixture position, but to limit such adjustment so that the fixture cannot interfere with the poles or other elements defining the patient-receiving gap of the magnet during movement of the patient support.
