Abstract

A system for estimating a volume of activation around an implanted electrical stimulation lead for a set of stimulation parameters includes a display; and a processor coupled to the display and configured to: receive a set of stimulation parameters including a stimulation amplitude and a selection of one of more electrodes of the implanted electrical stimulation lead for delivery of the stimulation amplitude; determine an estimate of the volume of activation based on the set of stimulation parameters using the stimulation amplitude and a database including a plurality of planar distributions of stimulation threshold values and a map relating the planar distributions to spatial locations based on the one or more electrodes of the implanted electrical stimulation lead selected for delivery of the stimulation amplitude; and output on the display a graphical representation of the estimate of the volume of activation.

Claims (34)

1 . A method for estimating a volume of activation around an implanted electrical stimulation lead for a set of stimulation parameters, the method comprising:

providing a database comprising a plurality of planar distributions of stimulation threshold values and an index identifying the planar distributions that correspond to angular locations around the implanted electrical stimulation lead based on a selection of one or more electrodes of the implanted electrical stimulation lead for delivery of stimulation, wherein each of the planar distributions represents a set of regions in a plane relative to the implanted electrical stimulation lead and each of the stimulation threshold values corresponds to a different one of the regions and comprises a stimulation amplitude that when applied to the selected one or more electrodes of the implanted electrical stimulation lead will stimulate tissue at the one of the regions corresponding to the stimulation threshold value;

receiving a set of stimulation parameters comprising a first stimulation amplitude and a first selection of one of more electrodes of the implanted electrical stimulation lead for delivery of the first stimulation amplitude;

determining an estimate of the volume of activation using the first stimulation amplitude, the first selection of one or more electrodes of the implanted electrical stimulation lead, and the database; and

displaying a graphical representation of the estimate of the volume of activation.

2 . The method of claim 1 , wherein the database consists of the plurality of planar distributions, wherein each of the planar distributions is unique.

3 . The method of claim 2 , wherein the database is a lossless compressed database.

4 . The method of claim 2 , wherein the database is a lossy compressed database.

5 . A system for estimating a volume of activation around an implanted electrical stimulation lead for a set of stimulation parameters, the system comprising:

a display; and

a processor coupled to the display and configured to:

provide a database comprising a plurality of planar distributions of stimulation threshold values and an index identifying the planar distributions that correspond to angular locations around the implanted electrical stimulation lead based on a selection of one or more electrodes of the implanted electrical stimulation lead for delivery of stimulation, wherein each of the planar distributions represents a set of regions in a plane relative to the implanted electrical stimulation lead and each of the stimulation threshold values corresponds to a different one of the regions and comprises a stimulation amplitude that when applied to the selected one or more electrodes of the implanted electrical stimulation lead will stimulate tissue at the one of the regions corresponding to the stimulation threshold value;

receive a set of stimulation parameters comprising a first stimulation amplitude and a first selection of one of more electrodes of the implanted electrical stimulation lead for delivery of the first stimulation amplitude;

determine an estimate of the volume of activation using the first stimulation amplitude, the first selection of one or more electrodes of the implanted electrical stimulation lead, and the database; and

output on the display a graphical representation of the estimate of the volume of activation.

6 . The system of claim 5 , wherein the selection of the one or more electrodes is characterized by at least one fractionalization parameter.

7 . The system of claim 6 , wherein the at least one fractionalization parameter comprises at least one of an axial position parameter, an angular direction parameter, or an angular spread parameter.

8 . The system of claim 5 , wherein the first selection of the one or more electrodes is characterized by at least one of an axial position parameter, an angular direction parameter, or an angular spread parameter.

9 . The system of claim 5 , wherein the index comprises a plurality of entries, wherein each of the entries is indexed to the selection of the one or more electrodes and an angular location around the implanted electrical stimulation lead.

10 . The system of claim 9 , wherein at least two of the entries of the index point to a same planar distribution.

11 . The system of claim 10 , wherein the at least two of the entries comprise a first entry indexed to a selection of a first one of the electrodes and a first angular location and a second entry indexed to a selection of a second one of the electrodes and a second angular location, wherein the first angular location and the second angular location differ by a first angle, wherein a location of the first one of the electrodes differs from a location of the second one of the electrodes by the first angle.

12 . The system of claim 5 , wherein the database consists of the plurality of planar distributions, wherein each of the planar distributions is unique.

13 . The system of claim 12 , wherein the database is a lossless compressed database.

14 . The system of claim 12 , wherein the database is a lossy compressed database.

15 . A non-transitory computer-readable medium having computer executable instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform the instructions, the instructions comprising:

providing a database comprising a plurality of planar distributions of stimulation threshold values and an index identifying the planar distributions that correspond to angular locations around the implanted electrical stimulation lead based on a selection of one or more electrodes of the implanted electrical stimulation lead for delivery of stimulation, wherein each of the planar distributions represents a set of regions in a plane relative to the implanted electrical stimulation lead and each of the stimulation threshold values corresponds to a different one of the regions and comprises a stimulation amplitude that when applied to the selected one or more electrodes of the implanted electrical stimulation lead will stimulate tissue at the one of the regions corresponding to the stimulation threshold value;

receiving a set of stimulation parameters comprising a first stimulation amplitude and a first selection of one of more electrodes of the implanted electrical stimulation lead for delivery of the first stimulation amplitude;

displaying a graphical representation of the estimate of the volume of activation.

16 . The non-transitory computer-readable medium of claim 15 , wherein the index comprises a plurality of entries, wherein each of the entries is indexed to the selection of the one or more electrodes and an angular location around the implanted electrical stimulation lead.

17 . The non-transitory computer-readable medium of claim 16 , wherein at least two of the entries of the index point to a same planar distribution.

18 . The non-transitory computer-readable medium of claim 15 , wherein the database consists of the plurality of planar distributions, wherein each of the planar distributions is unique.

19 . The non-transitory computer-readable medium of claim 18 , wherein the database is a lossless compressed database.

20 . The non-transitory computer-readable medium of claim 18 , wherein the database is a lossy compressed database.
