Abstract
An NMR blood flowmeter applies a continuous transverse excitation signal and a constant, homogeneous polarizing magnetic field to blood flowing through an active region. The polarizing magnetic field is contoured at opposite boundaries of this active region, and by switching these contours and collecting the resulting NMR signals, data is obtained from which the various components of blood flow may be calculated.
