Abstract

Various embodiments herein provide for representing measurement information during a medical procedure. Pose information is determined for one or more sensors. Measurements for the one or more sensors are then determined. The measurements can include measurements (e.g., temperature, radiation levels, etc.) of the sensors themselves as well as estimated measurements for other parts of the medical scene determined based on the sensors. After receiving the measurements, the measurements may be displayed relative to the rest of the procedure in a rendered 3D scene so that the doctor may be able to see measurements for various parts of the medical scene. Other embodiments herein provide for reducing the number of trackers needed to track and display a medical procedure based on a 3D model of the scene.

Claims

1. A method for representing measured information during a medical procedure, implemented on one or more computing devices, comprising:

determining the pose information for one or more sensors;

determining current measurements for the one or more sensors;

determining, using the one or more computing devices, the pose of the one or more sensors relative to a medical scene based on the pose information for the one or more sensors; and

displaying, using the one or more computing devices, the medical scene and the current measurements for the one or more sensors posed relative to the medical scene.

2. The method of claim 1, wherein the one or more sensors comprise two or more sensors.

3. The method of claim 1, wherein the one or more sensors comprise one or more temperature sensors.

4. The method of claim 1, wherein the one or more sensors comprise one or more radiation sensors.

5. The method of claim 1, wherein the method further comprises:

determining updated measurements for the one or more sensors; and

displaying, using the one or more computing devices, the medical scene and the updated measurements for the one or more sensors posed relative to the medical scene.

6. The method of claim 5, wherein

the method further comprises determining updated pose information for one or more sensors;

and

wherein displaying the medical scene and the updated measurements comprises displaying the updated measurements for the one or more sensors relative to the medical scene based on the updated pose information for one or more sensors.

7. The method of claim 1, wherein determining current measurements comprises estimating one or more measurements at one or more certain locations based on the poses and measurements of the one or more sensors, said one or more certain locations being separate and distinct from locations of the one or more sensors.

8. The method of claim 1, wherein displaying the medical scene and the current measurements comprises rendering a 3D view of a tracked ablation procedure.

9. The method of claim 1, wherein the one or more sensors comprise one or more temperature probes used in a medical procedure associated with the medical scene.

10. The method of claim 1, wherein the one or more sensors comprise one or more temperature sensors coupled to an ultrasound wand.

11. The method of claim 1, wherein the one or more sensors comprise one or more temperature sensors associated with an ablation needle.

12. The method of claim 1, wherein determining the poses of the one or more sensors comprises determining the poses of the one or more sensors based on tracking information.

13. The method of claim 1, wherein determining the poses of the one or more sensors comprises determining the poses of the one or more sensors based at least in part on a manufacturing specification.

14. The method of claim 1, wherein determining the poses of the one or more sensors comprises determining the poses of the one or more sensors based on a relationship to an object at least temporarily fixed with respect to the medical scene.

15. A computer-readable storage medium comprising computer-executable instructions for representing measured information during a medical procedure, said computer-executable instructions, when running on one or more computing devices, performing a method comprising:

determining the pose information for one or more sensors;

determining current measurements for the one or more sensors;

determining, using the one or more computing devices, the pose of the one or more sensors relative to a medical scene based on the pose information for the one or more sensors; and

displaying, using the one or more computing devices, the medical scene and the current measurements for the one or more sensors posed relative to the medical scene.

16. A system for representing measured information during a medical procedure, comprising one or more computing devices, said computing devices being configured to:

determine, at a first time, a first pose for each of one or more sensors;

determine first measurements related to the one or more sensors;

display a medical scene and the first measurements for the one or more sensors, said first measurements being posed with respect to the medical scene based on the determined first pose for each of the one or more sensors relative to the medical scene;

determine, at a second time different from the first time, a second pose for each of the one or more sensors;

determine second measurements for the one or more sensors;

display the medical scene and the second measurements for the one or more sensors, said second measurements being posed with respect to the medical scene based on the second pose for each of the one or more sensors.

17. The system of claim 16, wherein determining the first measurements comprises estimating one or more temperatures at one or more certain locations based on the poses and measurements of the one or more sensors, said one or more certain locations being separate and distinct from locations of the one or more sensors.

18. The system of claim 16, wherein the one or more sensors comprise one or more temperature sensors.

19. The system of claim 16, wherein the one or more sensors comprise one or more radiation sensors.

20. The system of claim 16, wherein determining the poses of the one or more sensors comprises determining the poses of the one or more sensors based on tracking information.
