Abstract

A tool for assisting in the planning or performing of electrical neuromodulation of a patient'"'"'s spinal cord. The tool may have various functions and capabilities, including calculating a volume of activation, registering an electrode(s) shown in a radiologic image, constructing functional images of the patient'"'"'s spinal anatomy, targeting of neuromodulation, finding a functional midline between multiple electrodes, determining the three-dimensional position of multiple electrodes, and/or accommodating for electrode migration. In certain embodiments, the tool can be embodied as computer software or a computer system.

Claims

1-19. -19. (canceled)

20. A method for assisting the planning or performing of neuromodulation in a patient, comprising:

receiving a radiologic image of the patient showing one or more electrodes inside the patient;

locating the one or more electrodes in the radiologic image, wherein the one or more electrodes collectively include multiple electrode contacts;

determining a functional midline for the one or more electrodes; and

displaying on a display screen, an image of an anatomic region and the one or more electrodes such that the functional midline of the one or more electrodes is aligned to the physiologic midline of the anatomic region.

21. The method of claim 20, wherein the step of determining the functional midline comprises:

receiving information about the relative electrical neuromodulation intensity between a first electrode contact among the multiple electrode contacts and a first counterpart electrode contact among the multiple electrode contacts; and

based on the relative electrical neuromodulation intensities, determining a first midpoint between the first electrode contact and the first counterpart electrode contact.

22. The method of claim 21, wherein the step of determining the functional midline further comprises:

receiving information about the relative electrical neuromodulation intensity between a second electrode contact among the multiple electrode contacts and a second counterpart electrode contact among the multiple electrode contacts;

based on the relative electrical neuromodulation intensities, determining a second midpoint between the second electrode contact and the second counterpart electrode contact; and

establishing the functional midline as a line between the first midpoint and the second midpoint.

23. The method of claim 21, wherein multiple electrodes are located in the radiologic image;

and wherein the first electrode contact is on a first one of the multiple electrodes and the first counterpart electrode contact is on a second one of the multiple electrodes.

24. The method of claim 23, wherein the step of determining the functional midline further comprises:

receiving information about the relative electrical neuromodulation intensity between a second electrode contact on the first one of the multiple electrodes and a second counterpart electrode contact on the second one of the multiple electrodes;

based on the relative electrical neuromodulation intensities, determining a second midpoint between the second electrode contact and the second counterpart electrode contact; and

establishing the functional midline as a line between the first midpoint and the second midpoint.

25. The method of claim 23, further comprising determining the relative position of the multiple electrodes in relation to each other.

26. The method of claim 21, wherein the relative electrical neuromodulation intensity between the first electrode contact and the first counterpart electrode contact is an electrode neuromodulation setting that produces a parasthesia that is centered on the patient'"'"'s body.

45. The method of claim 20, wherein the neuromodulation is spinal cord neuromodulation and the anatomic region is a spinal cord.

27. A computer system that is programmed to perform steps that comprise:

receiving a radiologic image of the patient showing one or more electrodes inside the patient;

locating the one or more electrodes in the radiologic image, wherein the one or more electrodes collectively include multiple electrode contacts; and

determining a functional midline for the one or more electrodes.

28. A non-transitory computer-readable storage medium comprising instructions executable by a computer processor, the instructions which, when executed by the processor, cause the processor to perform a method, the method comprising:

receiving a radiologic image of the patient showing one or more electrodes inside the patient;

locating the one or more electrodes in the radiologic image, wherein the one or more electrodes collectively include multiple electrode contacts; and

determining a functional midline for the one or more electrodes.
