A system, method, device and computer program are provided for determining a physiological parameter of a body comprising blood perfused tissue. The system comprises a sensor, or a plurality of sensors. The sensor(s) receive first and second radiation from the blood perfused tissue. The sensor(s) generate a first signal relating to an amount of blood (x(t)), and a second signal relating to a speed of blood (v(t)). An evaluation unit of the system defines first and second signal fractions in the first and second signals, respectively. The evaluation unit performs an intrinsic check whether to accept or reject the signal fractions and optionally uses a cross-check algorithm that has as its input both signal fractions and the result of the intrinsic check. The physiological parameter is determined using, if the cross-check algorithm was performed, the first and/or second signal fraction if accepted by the cross-check algorithm.
