Abstract: A lighting device for an MRI system aperture has at least one LED lamp and a light guide plate, the light guide plate having an interior surface, an exterior surface and multiple end faces. The end faces include a first end face, a second end face and one or more other end faces. Light rays from the LED lamp enter the light guide plate through the first end face, and exit the light guide plate through the exterior surface. The inner surface is opposite the outer surface, and the second end face is opposite the first end face. This lighting device for an MRI system aperture reduces the volume occupied in the MRI system aperture and at the same time the light rays are gentle and produce an effect of gradual change, protecting the examination subject's eyes and dispelling nervous feelings and claustrophobia in the examination subject.

Abstract: An MRI apparatus and a bed board assembly with illumination are described. The MRI apparatus includes: a frame with a cavity; a support rail disposed in the cavity; a bed board, which enters or exits the cavity moveably via the support rail; and an illumination unit disposed in a front portion of the bed board, for emitting light to provide illumination when the MRI apparatus is performing a scan. Space inside the cavity may be saved, and an examination subject may have the impression of being in a more open and brighter space, alleviating the subject's discomfort or fear effectively.

Abstract: 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.

Abstract: 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.

Abstract: 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.
