| Outline of Final Research Achievements |
Though hypothermic brain treatment for a newborn baby who suffers from hypothetic ischemia is currently attempted in clinical scenes, there is no devices which measure the deep brain temperatures noninvasively, continuously and passively. Medical doctors require a device which measures the temperature at 5 cm depth within 1 ℃ both for accuracy and precision. In this research, a five-band microwave radiometer system for a measurement of deep brain temperatures has been developed. We did all kind of things to remove microbubbles in a circulating cooling water and to stabilize the temperatures of antenna cable and the whole system. Results show that in a phantom experiment, the system can measure the temperature at 5 cm depth from surface with 0.44 ℃ accuracy and 1.3 ℃ precision. Future subject is to use the integrated circuits for the system.
