Quadrature RF field coil for use in magnetic resonance

摘要: There is described a quadrature radio frequency (RF) coil design to be used with appropriate magnetic resonance imaging (MRI) hardware obtain images of the human body. The provides good RF field homogeneity over volume suitable for thoracic diagnostic imaging, and operates in mode as transmit and/or receive coil. use 0.33 tesla permanent, C shaped magnet vertical main but general applicability. includes two parallel annular coils connected at top bottom by plate conductors. plates are split longitudinally transversely across splits capacitors define modes resonant oscillation which can tuned separately independently same frequency, where fields mutually orthogonal. right angles conductors so that sample inserted through openings plates.
