Abstract
The disclosure is directed to rendering visual representations of VOAs by manipulating vertices of a three-dimensional (3-D) mesh structure. In one example, a processing circuitry of a computing device may receive a 3-D mesh structure having adjustable vertices. The processing circuitry may adjust the vertices to generate an adjusted shape of the 3-D mesh structure according to an intersection between activated tissue and non-activated tissue defined by one or more stimulation parameter values.
Claims20
A method comprising:
- receiving, by a graphics processing unit (GPU), a three-dimensional mesh structure associated with a plurality of electrodes of a lead and generated by a central processing unit (CPU) different from the GPU;
- receiving, by the GPU, tissue activation data defining an intersection between activated tissue and non-activated tissue;
- automatically adjusting, by the GPU, a relative location of one or more vertices of the three-dimensional mesh structure toward the intersection between the activated tissue and the non-activated tissue to generate an adjusted shape of the three-dimensional mesh structure according to the intersection between the activated tissue and the non-activated tissue;
- and
- controlling, by the GPU, a display interface to output a visual representation of the adjusted shape of the three-dimensional mesh structure.
