An array coil combines the advantages of smaller coils (high SNR) with those of larger coils (large measurement field). This type of RF coil is composed of separate multiple smaller coils, which can be used individually (switchable coil) or combined.
When used simultaneously, the elements can either be:
coupled array coils - electrically coupled to each other through common transmission lines or mutual inductance
isolated array coils - electrically isolated from each other with separate transmission lines and receivers and minimum effective mutual inductance, and with the signals from each transmission line processed independently or at different frequencies
phased array coils - multiple small coils arranged to efficiently cover a specific anatomic region and obtain high-resolution, high-SNR images of a larger volume. The data from the individual coils is integrated by special software to produce the high-resolution images.

An RF array coil consisting of 2 - 6 several separately resonant elements, 2 or more of which can be selected as the receiver coil at a particular time. Coils not in use are decoupled. The spatial information related to the coils of a receiver array are utilized, reference images are required, obtained with each array element and with a body coil. Fast parallel imaging techniques using surface multicoils, such as sensitivity encoding (SENSE) or simultaneous acquisition of spatial harmonics (SMASH), have recently raised interest in the field of MR imaging.

An RF array coil consisting of several separately resonant elements, any one of which can be selected as the receiver coil at a particular time. Coils not in use are decoupled. Applications of switchable coils include imaging the whole spine without patient repositioning (where the coil elements may collectively be known as a ladder coil), imaging of bilateral structures such as TMJ or orbit using separate coils, or imaging using a coil with selectable field of view.
