Abstract
A probe for a medical device with source and detector sensors is used to monitor or measure, or both, oxygen saturation levels in a tissue. In various specific implementations, the probe has at least two sources and at least one detector, at least one source and at least two detectors, and at least two sources and at least four detectors. A source of the probe is connected to at least one radiation source, which is external to the probe. A detector of the probe is connected to a photodetector, which is external to the probe.
