A device for monitoring human feet can include: a transmissive sheet configured to bear at least 90 kg supported at a height of no more than 23 cm, and a foot image capture system below the sheet. An optical image sensor can capture a field of view including at least 250 cm2 of the surface of the sheet. The device can have a central reflective element positioned below the sheet directly above the sensor and two outer mirrors such that two fields of view at least 250 cm2 each can be focused onto the sensor by a lens. Foot sole images can be automatically captured when a patient stands on the device. Images can be transmitted to a database and associated with the patient by analyzing the images for a unique predetermined metric.
