Minimally invasive image-based determination of the concentration of carbon dioxide (CO2) in exhaled breath |
| abstract |
Disclosed is a system and method for image-based determination of the concentration of carbon dioxide (CO 2 ) in exhaled breath. In one embodiment, an image of the exhaled airflow of an individual of interest is received. The image is captured using a medium wave infrared camera system having an optical filter tuned to the CO 2 infrared absorption band. The image is preprocessed to isolate a region of pixels containing the exhaled airflow, and intensity values of pixels in the identified region are normalized to a value of known radiation density, for example the nose or face of the individual. The image is analyzed to determine the CO 2 concentration levels of the exhaled airflow using a calibration curve that relates pixel intensity to CO 2 concentrations. The calibration curve is derived using a physics-based parametric model. The CO 2 concentration levels are determined and transmitted to a computer workstation. Various embodiments are disclosed. |
