According to the De-Broglie-Bohm theory of quantum mechanics, electrons are considered as particles that are 'guided' on a wave function and thus travel a certain trajectory to the detector screen. Drawn in are different trajectories belonging to different initial positions of the electron in front of the double slit. Depending on the initial position, the electron takes a different trajectory to the detector screen. The trajectories themselves, depend on the wave function. And the time behavior of the wave function is determined by the Schrödinger equation.

De-Broglie-Bohm theory makes the same predictions in the double-slit experiment as the Copenhagen interpretation of quantum mechanics - except that in the de-Broglie-Bohm interpretation, the electrons traverse a real trajectory, while in the Copenhagen interpretation they do not.
