Claim 30:
31. A method of measuring blood flow in a foot, the method comprising:
positioning a foot on a platform having a platform contact surface with a plurality of apertures, the platform having a plurality of PPG sets, each PPG set having at least one light source and at least one light detector and being biased toward the foot through one of the apertures in the platform contact surface, the foot producing a foot force toward the platform contact surface when positioned on the platform contact surface;
producing, by each PPG set, a biasing force with a magnitude substantially independent of the foot force;
directing, by the PPG sets, light into the foot;
receiving, by the PPG sets, reflection of the light directed into the foot; and
determining a blood flow characteristic from the received light.
