THE PROPOSED PROGRAM FOR MONITORING BODY TEMPERATUE UTILIZES PASSIVE, NONINVASIVE MICROWAVE RADIOMETRY TO MEASURE AND MONITOR CORE TEMPERATURE.

THE PROPOSED PROGRAM FOR MONITORING BODY TEMPERATUE UTILIZES PASSIVE, NONINVASIVE MICROWAVE RADIOMETRY TO MEASURE AND MONITOR CORE TEMPERATURE. A MICROWAVE RADIOMETER - A SENSITIVE MICROWAVE RECEIVER - ALLOWS THE MEASUREMENT OF NATURAL ELECTROMAGNETIC EMISSION FROM THE BODY AT MICROWAVE FREQUENCIES. DICKE RADIOMETERS DEVELOPED TO DATE [1,2] FOR DETECTION OF PATHOLOGIC CONDITIONS IN WHICH THERE ARE DISEASE-RELATED TEMPERATURE DIFFERENTIALS, IN PARTICULAR CANCEROUS TISSUE, HAVE DEMONSTRATED A MINIMAL DETECTABLE TEMPERATURE SENSITIVITY OF LESS THAN 0.1 DEG C. THE EXISTING RADIOMETER WILL BE MODIFIED TO ALLOW REMOTE WIRELESS SENSING UTILIZING A SMALL PRINTED CONTACT ANTENNA PREVIOUSLY DESIGNED [3] FOR THE EARLY DETECTION OF EXTRAVASATION OF INTRAVENOUS CYTOTOXIC DRUGS. THE MATERIAL USED FOR THE PRINTED ANTENNA IS FLEXIBLE, PROVIDING THE ABILITY TO CONFORM TO THE BODY SURFACE. THIS ANTENNA, COUPLED WITH A SINGLE POLE DOUBLE THROW DIODE SWITCH AND LOW NOISE AMPLIFIER FOLLOWED BY AN OUTPUT OR COUPLING ANTENNA, WILL FORM A MINIATURE MONOLITHIC MICROWAVE INTEGRATED SUBSYSTEM ALLOWING THE TRANSMITTAL OF TEMPERATURE DATA TO THE REMOTE MONITORING SYSTEM.
