A portable diagnostic device for cardiac magnetic field mapping
Open accessAbstract
In this paper we present a portable magnetocardiography device.The focus of this development was delivering a rapid assessment of chest pain in an emergency department.The aim was therefore to produce an inexpensive device that could be rapidly deployed in a noisy unshielded ward environment.We found that induction coil magnetometers with a coil design optimised for magnetic field mapping possess sufficient sensitivity ( -/ 104 fT Hz 1 2 noise floor at 10 Hz) and response ( m - 813 fT V 1 at 10 Hz) for cycle averaged magnetocardiography and are able to measure depolarisa- tion signals in an unshielded environment.We were unable to observe repolarisation signals to a reasonable fidelity.We present the design of the induction coil sensor array and signal processing routine along with data demonstrating performance in a hospital environment.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
