Abstract
A microwave energy delivery and measurement system, including a microwave energy source configured to delivery microwave energy to a microwave energy delivery device, a measurement system configured to measure at least one parameter of the microwave energy delivery device and a switching network configured to electrically isolate the microwave energy source and the measurement system. The measurement system is configured to actively measure in real time at least one parameter related to the microwave energy delivery device.
Claims17
A microwave generator system comprising:
- a microwave energy source configured to generate a microwave energy signal;
- a transmission line coupled to the microwave energy source and configured to carry the microwave energy signal from the microwave energy source to a microwave energy delivery device for treating tissue;
- a measurement system coupled to the transmission line;
- and
- a switching network coupled to the transmission line and configured to couple the microwave energy delivery device to the microwave energy source for a first period and to couple the microwave energy delivery device to the measurement system for a second period after the first period.
A method of controlling a microwave generator, comprising:
- switching an output of the microwave generator to the output of a microwave energy source of the microwave generator;
- controlling the microwave energy source to generate a microwave energy signal during a first period;
- switching the output of the microwave generator to an input of a measurement system of the microwave generator;
- and
- controlling the measurement system to measure a parameter of a microwave energy signal during a second period after the first period.
