Abstract
A device, system and method for measuring free gas in a cavity of a subject. The device, system and method include a light source for emitting light with a wavelength associated with an absorption band of the free gas, an optical fibre connected to the light source and adapted to be inserted using an introducing member for internal illumination, and a detector adapted to be positioned on a skin surface for detecting light transmitted through the tissue. The device, system and method further includes a control unit for evaluating the detected transmitted light for determining the free gas, or a distribution of the free gas, or concentration of the free gas.
