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 human forearm. Two calibration procedures are described: one for pulsatile flows and the other for flows with a high non-pulsatile component. Flow measurements from normal arms, from limbs with arterial obstruction, arteriovenous hemodialysis fistulas or other conditions are reported. An application of the flow scanning technique for separation of flow signals from individual arteries (e.g., ulnar and radial) is described. The flat crossed-coil NMR flowmeter was applied to detect blood flow from individual arteries (e.g., brachial, popliteal, etc.). Applications of a ranging technique developed to detect signals at predetermined depths are described.
核磁共振（NMR）能够对血流信号进行非侵入性测量，且不受衣物、绷带、石膏等影响。采用圆柱形交叉线圈核磁共振血流仪测量通过人体前臂横截面的血流量。文中描述了两种校准程序：一种用于脉动血流，另一种用于具有高非脉动成分的血流。报告了正常手臂、患有动脉阻塞、动静脉血液透析瘘管或其他病症的肢体的血流测量结果。描述了一种用于从各个动脉（如尺动脉和桡动脉）分离血流信号的血流扫描技术的应用。平板交叉线圈核磁共振血流仪用于检测各个动脉（如肱动脉、腘动脉等）的血流。描述了一种为在预定深度检测信号而开发的测距技术的应用。
