Claim:
1. A method comprising: positioning a sensor head of a tissue oximeter to face toward a tissue, wherein the tissue oximeter can measure oxygen saturation of the tissue without requiring a pulse, the sensor head comprises a first source structure, a second source structure, a far detector arrangement, a near detector arrangement, and a semitranslucent film covering the near detector arrangement; transmitting light through the first source structure and the second source structure into a tissue; receiving a first light transmitted through the tissue and the semitranslucent film covering the near detector arrangement at the near detector arrangement, the first received light at the near detector arrangement including attenuation characteristics due to the semitranslucent film; receiving a second light transmitted through the tissue at the far detector arrangement, the second received light not passing through the semitranslucent film, and the second received light at the far detector arrangement not including the attenuation characteristics; and processing the first and second received light using a system unit.
