Using diamonds to make magnetocardiography cost effective

There have been great strides made in the past year or so in our ability to diagnose diseases more quickly and efficiently than is currently the case.  Most of these revolve around the use of machine learning to consume vast quantities of data and develop the ability to identify patterns that humans miss.

That isn’t the only approach being pursued however, as a recent study illustrates.  The paper describes a variant on the traditional method of monitoring the electric fields that pulse throughout the body as charges move through nerves and across muscles.  We have long used this as a means of detecting heart and brain issues, but this process also produces magnetic fields, and the authors believe that measuring this can be equally useful.  Indeed, because magnetic sensors don’t need skin contact to work, they could be more practical than existing methods, and help us to measure for issues in burns victims, for instance.
