Abstract
Nuclear magnetic resonance spectroscopy catheter probe comprising a permanent magnet arrangement (1,2,3,4) for generating a static magnetic field of suitable intensity and homogeneity for analysing a sample of fluid flowing into a catheter (6) traversing the permanent magnet arrangement. The probe further comprises an arrangement of electronic circuits (8,9) responsible for the excitation and detection of the nuclear magnetic resonance signal and at least one coil (7) to expose the fluid sample to the excitation signal and to collect the returned nuclear magnetic resonance signal.
