Apparatus for non-galvanic connection of MRI receive coil to MRI system by using RF-over-fiber

A magnetic resonance (MR) receive device comprises a coil or coil array including at least one radiofrequency (RF) coil element, wherein each RF coil element comprises a coil and a preamplifier connected to amplify an output of the RF coil element to generate an amplified RF signal. The MR receive device further includes an RF-over-Fiber module comprising an optical fiber, a photonic device optically coupled to send an optical signal into the optical fiber, and an RF modulator connected to modulate the optical signal by an MR signal comprising the amplified RF signal. 一种磁共振(MR)接收设备包括线圈或线圈阵列，所述线圈或线圈阵列包括至少一个射频(RF)线圈元件，其中，每个RF线圈元件包括线圈和前置放大器，所述前置放大器被连接以放大所述RF线圈元件的输出，从而生成放大的RF信号。所述MR接收设备还包括光纤上RF传输模块，所述光纤上RF传输模块包括光纤、光子设备以及RF调制器，所述光子设备被光学耦合以将光学信号发送到所述光纤中，所述RF调制器被连接以通过包括所述放大的RF信号的MR信号来调制所述光学信号。
