Magnetic detectors that record fetal heart rates arenâ??t available in medical clinics today. But one could be traveling by truck in a few years, thanks to a $3.2 million National Institutes of Health grant awarded last month to a company in Rice Lake. Shared Medical Technology Inc. operates mobile units housing MRI, CT and bone density scanners. The company is working on a portable version of the magnetic detector used to monitor fetal heart rhythms at UW-Madisonâ??s Wisconsin Institutes for Medical Research.
