摘要： The present invention relates to a magnetic resonance imaging system (1) comprising a plurality of RF coils (4) forming a multi-coil array and furthermore to a magnetic resonance imaging method for such a system. In order to provide an MR imaging system and method in which a desired excitation pattern is achieved in a simple way, it is suggested to utilize an analytical procedure how to combine the single coil elements to obtain the most homogeneous Bl excitation possible with a given coil array. In other words, the homogeneity of the Bl field is improved in a very simple way. The sensitivity of each RF coil (4) of the coil array is scaled or weighted by a complex factor, i.e. phase and amplitude of each coil drive signal is adjusted accordingly. These complex factors are determined analytically utilizing the sensitivities S (8) of the coil elements (4) and the desired excitation pattern P (IO, 11). The invention allows an optimized control of the field distribution (RF shimming) for arbitrary RF coil arrays. With the invention a fast and easy independent phase and amplitude control of the coil elements (4) is provided for reducing body- induced RF non- uniformities, which appear in high field MR systems.

摘要： An electric impedance imaging system is presented in which the electrical permittivity and/or conductivity distribution is derived on the basis of magnetic resonance signals. The magnetic resonance signals are generated due to an excitation electro-magnetic field. Notably, a magnetic induction field strength is derived from the acquired magnetic resonance signals. Also the electrical field strength associated with the excitation electro-magnetic field is computed. The electrical permittivity and/or conductivity distribution is computed on the basis of the electric field strength and the magnetic induction field strength.

摘要： For detuning of radio-frequency coils (in magnetic resonance imaging and spectroscopy, for example), a conducting element (102) of a transmission cable is configured to form a primary resonant circuit tunable to at least one first resonance frequency. A second conducting element (104) of the transmission cable is configured to form a switching circuit that is electrically insulated from and reactively coupled to the primary resonant circuit, and is adapted to tune the primary resonant circuit to at least one second resonance frequency.
