1. A computer system for generating an estimated volume of activation (VOA), the system comprising:

  • a computer processor configured to;

    for each of a plurality of neural elements that are in a vicinity of a leadwire;

    determine a respective threshold activation value; and

    determine whether a user-input stimulation value to be applied to the leadwire meets the respective threshold activation value of the respective neural element; and

    generate a surface structure corresponding to those of the neural elements whose respective threshold activation values have been determined to be met by the user-input stimulation value;

    wherein, for each of the plurality of neural elements, the determination of the respective threshold activation value includes;

    determining at least one of a peak voltage level along the respective neural element or a peak second difference voltage values along the respective neural element; and

    obtaining the respective threshold activation value based on the respective determined at least one of the peak voltage level or the peak second difference voltage value.
