A method and system are presented for use in non-invasive measurements in a subject (e.g. patients body). According to this technique, measurements are performed on a measurement location in the subject by applying an external electromagnetic field to the measurement location and detecting at least two responses of the measurement location, and generating data indicative of the detected response. These at least two responses are characterized by at least two different values of a certain controllable parameter. The measurements include measurements carried out under a normal blood flow condition in the measurement location enabling generation of first measured data indicative of a first time variation of the response for each of the at least two parameter values, and include measurements sessions carried out under a condition of artificial kinetics in the measurement location enabling generation of second measured data indicative of a second time variation of the response for each of said at least two parameter values. The first and second measured data are processed to determine a first relation between the first time variations for the different parameter values and a second relation between the second time variations for said different parameter values. The first and second relations are utilized to determine the at least one blood and/or tissue related parameter.La présente invention concerne un procédé et un système destinés à une utilisation dans des mesures non invasives dans un sujet (par exemple le corps dun patient). Selon cette technique, des mesures sont effectuées sur un emplacement de mesure dans le sujet en appliquant un champ électromagnétique externe sur lemplacement de mesure et en détectant deux ou plusieurs réponses de lemplacement de mesure, et en générant des données indicatives de la réponse détectée. Ces deux ou plusieurs réponses sont caractérisées par deux ou plusieurs valeurs différentes dun certain paramètre pouvant être commandé. Les mes
