Abstract
An apparatus for measuring a target tissue temperature is provided. The sensor antenna may include an outside and a contact side. A sensor antenna measurement aperture may be disposed on the contact side. The sensor antenna measurement aperture may be configured to generate a first signal. A skin temperature sensor may be disposed on the contact side and configured to generate a second signal. A radiometer may be configured to receive the first signal and the second signal.
Claims17
An apparatus for measuring a target tissue temperature comprising:
- a sensor antenna including an outside and a contact side;
- a sensor antenna measurement aperture disposed on the contact side, the sensor antenna measurement aperture configured to generate a first signal;
- a skin temperature sensor disposed on the contact side, the skin temperature sensor configured to generate a second signal;
- and
- a radiometer, configured to receive the first signal and the second signal, in electrical communication with the sensor antenna, the sensor antenna measurement aperture, and the skin temperature sensor, wherein the radiometer comprises at least one circulator, a radiofrequency (RF) board, and a signal processing board.

A method to measure a target tissue temperature comprising:
- disposing a sensor antenna on a patient's skin, the sensor antenna including a sensor antenna measurement aperture and a skin temperature sensor;
- detecting, via the sensor antenna, a first signal comprising plurality of microwave emissions from a measurement volume of tissues, the measurement volume of tissues comprising a plurality of tissue layers;
- detecting, via the skin temperature sensor, a second signal corresponding to a patient's skin temperature;
- transmitting the first and second signal to a radiometer as a sensor input;
- processing, via the radiometer, the input, wherein the radiometer comprises at least one circulator, a radiofrequency (RF) board, and a signal processing board;
- calculating, via the radiometer, an average temperature of the measurement volume of tissues from the sensor input;
- and
- calculating the target tissue temperature via the equation:
- T
