Abstract

Disclosed are an RF coil receiving device using an optical link in a magnetic resonance imaging device, a magnetic resonance system using same, and a data processing method for the RF coil receiving device. The RF coil receiving device using an optical link in a magnetic resonance imaging device comprises: a coil which detects electric signals generated in the human body which is scanned with the magnetic field generated by the magnetic resonance imaging system; a detune unit which separates the coil from an external circuit by preventing strong RF power, which is generated when the signals from the human body detected by the coil are transmitted, from being induced in the coil; a low-noise amplification unit which amplifies the signals from the human body to improve the signal-to-noise ratio thereof; an impedance matching unit which matches the impedance between the low-noise amplification unit and a laser diode; a laser diode which converts the impedance-matched signal into an optical signal; and a power control unit which generates DC power by using the optical signal outputted from a scan control unit to supply the DC power to at least one of: the detune unit, the low-noise amplification unit, the impedance matching unit, and the laser diode.} According to the present invention, many coil elements can be integrated, and thus, portions of the human body can be easily and variously imaged. Further, since an area of concern can be further subdivided, the correct image of the human body can be acquired and the time taken for acquiring the image can be shortened. Moreover, the signal-to-noise ratio and transmitting speed of the signals are improved, and thus, a high-quality image can be acquired.
