Abstract
An oximeter measures oxygen saturation for two or more different tissue depths and shows these results on a screen. A probe of the oximeter has multiple different distances between source and detector sensors. One probe implementation has fixed sensor positions. Other implementations include sensors on a moveable platform or openings to accept sensors, which allow a user to vary a distance between sensors.
