Surface coil

Patent Granted Surface coils are designed to provide a very high RF sensitivity over a small region of interest. These coils are often single or multi-turn loops which are placed directly over the anatomy of interest. The size of these coils can be optimized for the specific region of interest. Surface coils make poor transmit coils because they have poor RF homogeneity, even over their region of interest. Their small field of view makes them ideal for receive, as they only detect noise from the region of interest.
