Abstract
A method for determining whether a sensor is coupled to a tissue sample is described. The sensor is operable to generate a detector signal indicative of absorption of electromagnetic radiation by the tissue sample. A plurality of metric values corresponding to the detector signal are generated. A neural net is employed with the metric values to determine whether the sensor is coupled to the tissue sample.
