Abstract

A measurement system and method for measuring at least one parameter in a body tissue comprise at least one measurement device to be applied to the body, an optical unit for emitting light waves, wherein at least one wavelength of the light waves lies in the region of the absorption of a body parameter, at least one light guide between the optical unit and the measurement device in order to transmit light waves, and an evaluation unit for evaluating measurement waves. Light waves emitted by the optical unit can be beamed into an optical measurement volume in the body tissue by means of the measurement device, and measurement waves received by the measurement device from the measurement volume can be transmitted from the body tissue to the evaluation unit. The evaluation unit comprises a transformation algorithm, which transforms pulsatility of a body parameter measured in the measurement volume into a parameter of the pressure in the body tissue, wherein the body parameter is measured by determining the absorption of the light waves.
