Because it plays such an important role in determining the signal-to-noise ratio (SNR) in MR imaging and because it is one of the few elements of the imaging system that is easily modifiable by engineers and physicists, the radio-frequency (RF) detector coil has been the subject of significant research. More recently, investigators have begun using arrays of RF coils. RF coil arrays have already found widespread use in MRI, and should become more widely used as applications increase. Presently the most important use of RF coil arrays are to increase the SNR per unit time, increase the available field-of-view, or some combination of the two. Dynamic imaging appears to be another important potential application. An introduction to the theory and application of RF coil arrays is provided in this paper, and examples of several applications are shown.
