RF coil system in magnetic resonance imaging apparatus |
摘要 |
An RF coil system having (2n+1)/4 (n: zero or a positive integer) wavelength cables arranged in both ends of a PIN diode conneted in series with an RF coil, and a PIN diode is DC-biased via the aforementioned cable. A multi-band RF system constructed by providing a plurality of such wavelength cables corresponding to the frequencies of an RF pulse in obtaining an MR signal. Since the cable is, for example, of a coaxial type, the length of the cable is easy to adjust and it is thus possible to avoid coupling to the ambient environment.
