Abstract
A computer implemented system and method provides a volume of activation (VOA) estimation model that receives as input two or more electric field values of a same or different data type at respective two or more positions of a neural element and determines based on such input an activation status of the neural element. A computer implemented system and method provides a machine learning system that automatically generates a computationally inexpensive VOA estimation model based on output of a computationally expensive system.
Claims20
A system for estimating a volume of activation using a set of electrical stimulation settings, the system comprising:
- a processor configured to:
- receive electric field data and the set of electrical stimulation settings for use with a non-cylindrically symmetrical implanted leadwire;
- apply the electric field data and the set of electrical stimulation settings to a volume of activation estimation model to determine a value for each of one of more locations for each of a plurality of neural elements, wherein the volume of activation estimation model either 1) does not use as input a plurality of sets of values of an electrical field at different points in time, 2) includes only linear equations generated based on observed functioning of a model that uses differential equations, or 3) does not use more than one differential equation;
- output an indication of an estimated volume of activation based on the values for each of the one or more locations for each of the neural elements;
- and
- initiate a signal to convey the set of electrical stimulation settings to an implanted pulse generator to transmit signals via a leadwire for stimulation of patient tissue according to the set of electrical stimulation settings.
A non-transitory computer-readable medium having instructions stored thereon and executable by a processor, the instructions comprising:
- receiving electric field data and the set of electrical stimulation settings for use with a non-cylindrically symmetrical implanted leadwire;
- applying the electric field data and the set of electrical stimulation settings to a volume of activation estimation model to determine a value for each of one of more locations for each of a plurality of neural elements, wherein the volume of activation estimation model either 1) does not use as input a plurality of sets of values of an electrical field at different points in time, 2) includes only linear equations generated based on observed functioning of a model that uses differential equations, or 3) does not use more than one differential equation;
- outputting an indication of an estimated volume of activation based on the values for each of the one or more locations for each of the neural elements;
- and
- initiating a signal to convey the set of electrical stimulation settings to an implanted pulse generator to transmit signals via a leadwire for stimulation of patient tissue according to the set of electrical stimulation settings.
