Abstract
The invention relates to a coil and coupling arrangement for use in equipment based on magnetic resonance, which arrangement can be applied e.g. to magnetic resonance imaging (MRI). The apparatus is adapted to operate on more than one polarizing magnetic field strength and the apparatus includes a coil arrangement for producing and detecting a resonance signal as well as for changing the energy states of spin systems. The operating states and physical properties, such as e.g. the resonance frequency, of the coil arrangement are changed by using switches or couplings whose state is controlled by the polarizing magnetic field.
