摘要：
Medical apparatus includes a probe, having a distalsegment configured for insertion into a body of a patient.The probe includes at least one optical sensing unit, whichis disposed along the distal segment and includes first andsecond radiation sources, configured to emit opticalradiation in different, respective, first and secondwavelength bands toward tissue in the body in proximity tothe distal segment. An opticalsensor is configured toreceive the optical radiation in the first and secondwavelength bands that is scattered from the tissue and tooutput first and second electrical signals responsively toan intensity of the received optical radiation.
