ABSTRACT:
A probehead of an MR apparatus according to this invention includes transmitting and receiving coil elements for transmitting an RF field and receiving an MR signal based on an MR phenomenon induced in an object to be examined, respectively, and switching units for controlling decoupling of the transmitting and receiving coil elements. At least the switching unit provided for the transmitting coil element includes a plurality of PIN diodes connected in parallel with each other, and reactance elements connected in series with the plurality of PIN diodes and having reactance components, absolute values of which are sufficiently larger than resistance components of the PIN diodes in an on-state.
