Method for transcranial neurostimulation. A target of neurons for transcranial stimulation or modulation is located within an impedance model of the brain, a model of a selected device to be used for producing an electric or magnetic field outside the brain is obtained and used, along with the impedance model, to compute respective virtual target stimulating current vectors representing target stimulating currents that would result from using the device in two distinct trial dispositions of the device, an image of the cortical surface at the target is obtained and used to compute a target normal vector, and a determination is made of which of the two virtual target stimulating current vectors has a greater component projecting at predetermined angles from the target normal vector.

Preferred systems can include an electrical impedance tomography apparatus electrically connectable to an object; an ultra low field magnetic resonance imaging apparatus including a plurality of field directions and disposable about the object; a controller connected to the ultra low field magnetic resonance imaging apparatus and configured to implement a sequencing of one or more ultra low magnetic fields substantially along one or more of the plurality of field directions; and a display connected to the controller, and wherein the controller is further configured to reconstruct a displayable image of an electrical current density in the object. Preferred methods, apparatuses, and computer program products are also disclosed.
