1. A method comprising:
receiving, by a processor, a plurality of detected electronic signals from a detector communicatively coupled to the processor, the plurality of detected electronic signals corresponding to light emitted from a pregnant mammal's abdomen and a fetus contained therein that has been detected by the detector and converted into the detected electronic signal, the emitted light being a portion of light projected, by a light source, into the pregnant mammal's abdomen and fetus contained therein;
isolating, by the processor, a portion of the plurality of detected electronic signals that correspond to light that was incident on the fetus using a time of flight for photons included in light that was incident on the fetus;
determining, by the processor, fetal oxygen saturation information using the isolated portion of the plurality of detected electronic signals; and
communicating, by the processor, an indication of the fetal oxygen saturation information to a display device.
