A system for measuring physiological parameters, including: a portable measurement system, operable to acquire physiological measurement from an examined body location; an external camera operable to capture visible light, oriented toward the examined body location; a synchronization module, operable to receive a triggering indication, and in response to the triggering indication to associate to the physiological measurement a positioning image captured by the camera, the positioning image including at least a part of the portable measurement system adjacent to the examined body location; and a communication module operable to obtain the physiological measurement and the positioning image, and to transmit to a remote system: a physiological measurement record based on the physiological measurement, an orientation image based on the positioning image, and including at least a part of the portable measurement system adjacent to the examined body location, and association data associating the orientation image and the physiological measurement record.
