摘要： A receiver coil array for a magnetic resonance imaging system has an inductive coupling coil incorporated in the middle coil unit of the receiver coil array as its secondary coil, which serves to regulate the frequency and impedance of the middle coil unit. The secondary coil has an output regulation circuit which can output the magnetic resonance signals received by the middle coil unit to increase the number of the coil units in the receiver coil array that receive and output resonance signals while further regulating the frequency and impedance of the middle coil unit. Since this receiver coil array achieves regulation of the frequency and impedance of the middle coil unit and increases the number of the coil units in the receiver coil array that receive and output the resonance signals, it can improve the quality of the signals received by the receiver coil array. Moreover, the design is simple and is easy to achieve.

摘要： A coil arrangement for a magnetic resonance apparatus has a number of coil elements that are capable of being operated independently of one another and are situated around a common central area. Each coil element of the coil arrangement is capacitively or inductively decoupled from the coil elements of the coil arrangement that are immediately adjacent to this coil element. In the central area, there is situated a capacitor network that connects the coil elements of the coil arrangement to one another. The capacitor network is fashioned and dimensioned such that it at least reduces the coupling of each coil element of the coil arrangement to at least one additional coil element of the coil arrangement that is not immediately adjacent to the respective coil element.

摘要： To reduce high SAR values in the field of magnetic resonance imaging, and particularly with a whole body coil assembly for an MRI apparatus, at least a bracket is added between the supporting tube of a whole body coil assembly and the connecting copper sheet in order to radially raise the connecting copper sheet and the capacitors away from the human body. In addition to effectively solving the problem of a high SAR value, at the same time no significant loss of the imaging performance occurs. Moreover, the structure is simple, so the costs of modification or production are low.

摘要： The present invention discloses a magnetic resonance imaging apparatus for scanning a spine, comprising a body coil for emitting signals, a patient table within the body coil and a spine coil for receiving signals, wherein said spine coil is fixed within said body coil and disposed under said patient table. Said patient table is movable within said body coil by slide rails fitted at the two sides thereof, so as to reduce the length of said spine coil. The cross section of said patient table is in an arched shape, and the cross section of said spine coil is in an arched shape which matches that of said patient table. By using the apparatus of the present invention, since the spine coil is disposed underneath the board of the patient table, the design and production of the board of the patient table are simplified, the number of radio frequency choke coils and radio frequency element units is reduced and so are the costs; also, the space for the patient is increased, so the patient's comfort is improved; and furthermore, the repeated plugging and unplugging of the spine coil, as in the prior art, are avoided so as to reduce the probability of damaging the coil.
