| Abstract: | Inhomogeneities in magnetic field density are not very critical in pulsating arterial flow, but may be an important consideration in venous flow and branch or asymmetric flow. In this regard, a blood flow probe design has been developed with a magnetic field distribution which varies less than 1% across the lumen. It is shown that the luminal fields of two commercially available probes vary as much as 25%. |
