This is a toolbox for DBS electric field and VTA estimation.
FastField consists of two independent stages: a fast electric field (e-field) estimation followed by a heuristic prediction of the VTA. Inputs for the e-field model are the electrode contact configuration, stimulation parameters and assumed tissue properties. Patient’s electrode location in the MNI space may be added for patient-specific studies.The subsequent VTA estimation allows to consider different pulse widths and axon diameters. The whole process is fully automatic and takes about 0.2 s on a standard computer.
Please run the example.m file to see how it works, note that you have to adapt the path to the FastField github directory and the patient directory on your computer.
