The present invention is directed to satisfying the need to measure and monitor uterine activity non-invasively and accurately. Using superconducting quantum interference device sensors, we have established the feasibility of recording uterine contractile activity with high enough spatial-temporal resolution to determine the regions of localized activation and propagation over the uterus. With the large surface area and the shape of the array, spatial-temporal recordings of uterine activity were obtained using 151 sensors yielding a better insight into the mechanism of uterine contraction. By obtaining a contour plot of the magnetic field distribution, we were able to localize the areas of activation over the uterus during a contraction. |
