Static and alternating magnetic fields are employed in blood flowmeters using nuclear magnetic resonance (NMR) principles and electromagnetic induction by a moving conductor (TEM). Both techniques require high steady magnetic fields, obtained either

Nuclear Magnetic Resonance (NMR) permits the noninvasive measurement of blood flow signals unimpaired by clothes, bandages, casts, etc. The cylindrical crossed-coil NMR blood flowmeter was used to measure blood flow through a cross-section of the hum

Nuclear magnetic resonance (NMR) techniques have been applied to the measurement of steady or quasi-steady flow by using, principally, the tag-detect method. This paper describes a two-magnet NMR flowmeter that can be used to measure pulsatile flow.

Nuclear magnetic resonance (NMR) signals were recorded from ordinary tap water 12 s after the fluid was magnetized upstream of the detector. Detection time was extended to 18 s with signal averaging. The time for a bolus of magnetized water to reach

The principles of nuclear magnetic resonance (NMR) have been employed in the design of noninvasive blood flowmeters. This paper describes an NMR limb blood flowmeter which has been used in statistical studies of normal volunteers, and diagnostically

Arterial blood flow signals have been obtained noninvasively from the posterior tibial artery, the brain, and the region of the heart at proton resonance frequencies of 21.4 MHz and 75 MHz. For these studies, the subjects were placed in a superconduc

A nuclear magnetic resonance (NMR) flowmeter has been developed for noninvasive measurement of upper extremity blood flow in humans. Flow through major arteries and veins is determined by placing the arm into a 12.5‐cm i.d. crossed‐coil detector

Research for the application of NMR principles to the noninvasive measurement of blood flow in humans began at the National Heart,Lung, and Blood Institute (NHLBI) in 1956, and has continued to the present at a number of institutions. In addition to
