Abstract
A local coil for an MRI imaging system includes an antenna containing a first detuning circuit and a second detuning circuit, and a connection connected to the antenna between a first connection point on the antenna and a second connection point on the antenna. The connection is configured to be short-circuited by at least one diode. The first connection point and the second connection point are situated spatially between a first partial region and a second partial region of the antenna.
