Abstract
Methods and systems for redundant power detection, including forward power and reverse power, utilize sensors separate from microwave power sensors. The redundant power detection can be compared to measurements of the microwave power sensors to ensure that the sensors are operating correctly.
Claims34
A microwave energy system comprising:
- a microwave energy source receiving power supplied from a power supply;
- an ablation probe coupled to the microwave energy source to receive a forward power from the microwave energy source;
- and
- a control system configured to:
- measure the power supplied to the microwave energy source by the power supply;
- determine lost power due to inefficiency of the microwave energy source;
- and
- determine the forward power from the microwave energy source by subtracting the lost power from the power supplied to the microwave energy source.
A method for power detection in an ablation microwave energy system, the method comprising:
- measuring power supplied to a microwave energy source by a power supply;
- determining lost power due to inefficiency of the microwave energy source;
- and
- determining forward power sent to an ablation probe from the microwave energy source by subtracting the lost power from the power supplied to the microwave energy source.
A non-transitory computer readable medium having instructions stored thereon that, when executed by a computing device, cause the computing device to:
- measure power supplied to a microwave energy source by a power supply;
- determine lost power due to inefficiency of the microwave energy source;
- and
- determine forward power sent to an ablation probe from the microwave energy source by subtracting the lost power from the power supplied to the microwave energy source.
