Abstract
An example magnetic resonance imaging (MRI) coil base apparatus for use with interchangeable attachable and detachable coil attachments is described. The coil base apparatus electrically and mechanically couples to different MRI coil attachments designed for imaging different body parts (e.g., ankles, knees, wrists, elbows, shoulders). The MRI coil base apparatus includes elements (e.g., channel, pre-amplifier, mixer, feed circuit, decoupling circuit) for controlling the coil attachment to transmit radio frequency (RF) energy that produces nuclear magnetic resonance (NMR) in an object exposed to the RF energy. The coil attachment includes elements that transmit the RF energy and a copper trace that receives resulting NMR signals. The coil base apparatus may include a slide apparatus for repositioning the coil attachment in one axis when the coil attachment is coupled to the coil base apparatus or a pivot apparatus for rotating the coil attachment when it is coupled to the coil base apparatus.
