MAGNETIC RESONANCE DETECTION COIL THAT IS IMMUNE TO ENVIRONMENTAL NOISE |
摘要 |
A noise immuned gradiometer split shield coil for use in magnetic resonance detection, such as in Nuclear Magnetic Resonance (NMR) and Nuclear Quadrupole Resonance (NQR). The coil is formed by a transmission line (50) configured as a magnetic field gradiometer. The transmission line has a conductor (58) which is electrically continuous through the coil, and a shield (60) which is split (56) at a position that causes the gradiometer to be electrically balanced. In this manner, the coil provides a high degree of internal shielding to reduce the effect of environmental noise pick-up. Such coils are also less sensitive to the effects of nearby conducting media.
