Clinician programmer system and method for steering volumes of activation
A system and method for selection of stimulation parameters for Deep Brain Stimulation (DBS) may include a processor that displays in a display device and in relation to a displayed model of a leadwire including model electrodes, a current field corresponding to a first stimulation parameter set, provides a user interface for receipt of user input representing a shift of the current field, in response to the user input, moves, in the display device, the current field with respect to the displayed model, determines a second stimulation parameter set that results in the moved current field, and outputs the second stimulation parameter set and/or sets a stimulation device with the second stimulation parameter set, where the stimulation device is configured for performing a stimulation using the leadwire in accordance with the second stimulation parameter set.
1. A method of a stimulation parameter selection machine, the method comprising:
creating, by a processor of the machine, a three-dimensional model of at least a portion of a patient's brain using one or more medical images of the patient's brain;
determining, by the processor, a volume of activation (VOA) using information about the patient selected from the group consisting of desired therapy outcome, patient condition, indications, or symptoms;
calculating, by the processor and based on the model, one or more stimulation parameters for a stimulation that results in the VOA, wherein the one or more stimulation parameters include a leadwire location;
displaying, on a display, the model and the VOA via a graphical user interface (GUI); and
displaying at the leadwire location, a leadwire model on model of at least a portion of the patient's brain.
2. The method of claim 1 , further comprising, after calculating the one or more stimulation parameters, implanting a leadwire at the leadwire location.
3. The method of claim 1 , wherein the one or more medical images comprises a magnetic resonance (MR) image.

5. The method of claim 1 , further comprising determining, by the processor, and outputting, by the processor, a burr hole location for insertion of a leadwire to implant the leadwire at the leadwire location.
6. The method of claim 5 , further comprising determining, by the processor, and outputting, by the processor, a path of the leadwire from the burr hole location to the leadwire location.
7. The method of claim 1 , further comprising determining, by the processor, and outputting, by the processor, an angle of entry for insertion of a leadwire to implant the leadwire at the leadwire location.
8. The method of claim 1 , wherein creating a three-dimensional model comprises fitting the one or more medical images to a pre-loaded atlas.
9. The method of claim 1 , further comprising selecting a target location using the model, wherein calculating the one or more stimulation parameters comprises calculating the one or more stimulation parameters using the target location.
10. The method of claim 1 , further comprising, in response to user actuation of a rotational directional button displayed on the display, shifting, by the processor, the VOA with respect to the displayed leadwire model rotationally about a longitudinal axis of the displayed leadwire model.
11. The method of claim 10 , further comprising determining, by the processor, one or more new stimulation parameters for a stimulation that results in the shifted VOA.
12. The method of claim 10 , wherein the rotational directional button comprises a first rotational directional button and a second rotational directional button, wherein actuation of first rotational directional button shifts the display of the VOA in an opposite rotational direction from an actuation of the second rotational directional button.
13. The method of claim 12 , wherein the longitudinal directional button comprises a first longitudinal directional button and a second longitudinal directional button, wherein actuation of first longitudinal directional button shifts the display of the VOA in an opposite longitudinal direction from the actuation of the second longitudinal directional button.
14. The method of claim 1 , further comprising in response to user actuation of a longitudinal directional button displayed on the display, shifting, by the processor, the display of the VOA with respect to the displayed leadwire model longitudinally parallel to a longitudinal axis of the displayed leadwire model.
