Abstract
A system including a thermal sensor with an instrument placed in a volume. The thermal sensor may be useful in determining a temperature at a surface of the instrument and a distance away from the instrument. A therapy may be performed based on a sensed temperature with the thermal sensors.
Claims19
A system to measure temperature in a region of interest, comprising:
- an instrument assembly including:
- an exterior housing have an external wall and extending from a first housing end to a second housing end and configured to be moved to a position within a volume,
- an energy delivery component configured to deliver energy to affect a thermal therapy at a region of interest within the volume outside of the exterior housing, wherein the energy delivery component is moveable within the exterior housing;
- a first temperature sensor to sense a temperature within the region of interest a distance spaced away from the external surface of the housing;
- an energy source configured to deliver energy through the energy delivery component to affect the thermal therapy in the region of interest;
- a tracking device embedded in the external wall;
- a processor configured to execute instructions to:
- determine a temperature profile within the region of interest based on a signal from the first temperature sensor, and
- determine a position of the instrument within the region of interest based upon the tracking device;
- wherein the thermal therapy is operable to increase a temperature in the region of interest.

A system to measure temperature in a region of interest, comprising:
- an instrument extending a length from a first end to a second end and configured to be moved to a position within a volume and deliver a thermal therapy to a region of interest within the volume;
- a temperature sensor to sense a temperature within the region of interest;
- an energy source configured to deliver energy to affect the thermal therapy in the region of interest;
- a tracking device having a coil connected near the first end of the instrument;
- and
- a navigation processor configured to determine a position the tracking device;
- wherein the thermal therapy is operable to increase a temperature in the region of interest.
4 more elements
A method to measure temperature in a region of interest, comprising:
- directing energy through an emitting portion of an energy delivery component to heat the region of interest;
- determining a temperature in the region of interest with a signal from a temperature sensor connected relative to the energy delivery component near the emitting portion;
- determining when a selected temperature in the region of interest is achieved by evaluating the signal from the temperature sensor;
- ceasing the heating of the region of the region of interest when the selected temperature is determined to be achieved;
- and
- tracking a position of the energy delivery component during movement of the energy delivery component into the region of interest.
