University of Leeds scientists have developed a portable magnetometer that offers a new level of sensitivity to magnetic fluctuations useful for early detection of a number of conditions, including heart problems in fetuses.
The human heart produces a distinctive magnetic signature; the magnetometer works by revealing tiny variations in that signature. Further study of these variations could help indicate the presence of a cardiac condition.
While large-scale magnetometers are used in directional drilling, on spacecraft, and for detecting submerged objects at archaeological sites, their size and high cost have prevented them from being used to identify heart conditions.
The team is working on miniaturizing the magnetometer for medical purposes. It is expected to be especially effective at detecting ischemia, a restriction in blood supply to an area of the body due to a blockage of blood vessels.
