Portable Diagnostic Radiometer.
Abstract
There exists a need for a portable diagnostic instrument that can noninvasively monitor and display internal body temperatures. This instrument would be extremely important on U.S. Navy ships whose complement does not include the services of competent medical professionals. In this case it would be important to determine whether a particular medical emergency does or does not exist in a patient. This would determine whether the patient should or should not be evacuated to a suitable medical facility for treatment. The instrument would determine, by radiometric means, whether particular organs exhibit an elevated temperature. For example, this may be an aid in the diagnosis of appendicitis or nephritis. The instrument described in this report is a dual-frequency microwave radiometer. The radiometer measures the amount of noise power being radiated from a localized tissue volume on the patient. The amplitude of this noise power over a frequency spectrum determined by the microwave components is proportional to the average temperature of the volume in question. Making this measurement at two separate frequencies can give an indication of the temperature profile over a depth as great as 6 cm. (Author)
