In parallel imaging a multi‐element RF receive array coil is used to provide additional spatial information, and to reduce the number of lines of signal required to form an image. Parallel imaging reduces the number of TR periods of an acquisition by an amount known as the reduction factor R, SENSE factor or iPAT factor. The use of parallel imaging reduces the patient’s overall RF exposure.
