    摘要： A magnetic resonance imaging (MRI) radio frequency (RF) coil array configured to operate in a transmit (Tx) mode or in a receive (Rx) mode, comprising: a plurality of rows configured in an anatomy-specific shape, a row including a plurality of RF coil elements, an RF coil element including an LC coil and a magnitude/phase control component, where the LC coil, upon resonating with a primary coil at the working frequency of the primary coil, generates a local amplified Tx field based on an induced current in the LC coil, where a magnitude or a phase of the induced current is independently adjustable, where the magnitude/phase control component is configured to adjust the magnitude or phase of the induced current, and where the magnitude or phase of the induced current of a first RF coil element is independently adjustable from that of a second, different RF coil element.

    摘要： An HF coil assembly for generating independent alternating magnetic fields in an examination volume of a magnetic resonance apparatus is presented, the HF coil assembly comprising a first coil pair of saddle coils and a second coil pair of saddle coils, each saddle coil having longitudinal conductor elements and curved conductor elements arranged along a common lateral surface of a circular cylinder having a cylinder axis. Each coil pair comprises curved conductor elements and longitudinal conductor elements which are interconnected at a high frequency. The saddle coils also have diagonal conductor elements and/or bridge elements that connect the longitudinal and curved conductor elements. The coil pairs are opposite to each other relative to the cylinder axis.

    摘要： 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.
