Abstract

The authors have developed a unique type of temperature-dependent optical sensor for deployment at the tip of the fiberoptic probe, consisting of a bulk semiconductor crystal whose optical absorption varies with temperature. The small diameter of the probe (about . 250 mm) minimizes tissue damage upon implantation. The authors have also developed a new means of noninvasive temperature mapping within the body, using ultrasound as the sensing beam. The technique is based up on the temperature-dependent velocity of sound exhibited by most biological tissues, and therefore a tomographic map of ultrasound velocity reconstructed by computerized reconstruction techniques may be related to internal organ temperatures. Precise calibration of the procedure may require the use of the invasive probes described in this paper.
