ABSTRACT:
An RF coil system for a magnetic resonance imaging apparatus whereby a substantially computer-aided and hence automatically optimized image quality in respect of signal-to-noise ratio and resolution can be achieved in dependence on the type and size of the object to be imaged, without time-consuming replacement or manual positioning of the RF coil system being necessary. To this end, the coil system (A) includes a plurality of single RF coils (Sx) which are essentially decoupled from one another and have a different size and/or different position, as well as a control device with a plurality of transmission units which are associated with a respective RF coil and whereby one or more RF coils can be selected and supplied with an RF pulse having an independently adjustable amplitude and/or phase and/or pulse shape. The invention also relates to a magnetic resonance imaging apparatus provided with such an RF coil system.
