Abstract
A device has various arrangements of source and detector sensors. In specific implementations, the device has at least four structures, one source and three detectors, two sources and two detectors, and other arrangement variations. In a specific implementation, between a source structure and a detector structure, there are not any other intervening sensor structures. The device may be part of a medical device that is used to monitor or measure oxygen saturation levels in a tissue.
