Abstract: A method for automatically aligning a model for an upper jaw with a model for a lower jaw, the method including forming models for teeth of the upper jaw and the lower jaw based on images; obtaining a reference bite frame with the teeth in a clenched state; aligning the models for the teeth of the upper jaw and the lower jaw with the reference bite frame, respectively, to determine transform information between the generated models and the reference bite frame; aligning the model for the teeth of the upper jaw with that of the lower jaw based on the determined transform information.

Abstract: A device and a method for creating a spatial dose distribution in a medium volume (22) are described. A laser system produces laser pulses (12) with a pulse length shorter than 200 fs (femtoseconds) and is capable to be focused to peak intensities greater than 10^18 W/cm^2 (watts per centimeter squared). An electron source (18) is capable of releasing a high-energy electron pulse (20), in particular the electrons having an energy greater than 100 MeV, upon irradiation with said laser pulses (12) propagating into the medium volume (22). The light paths (52, 56,58) of at least some of the laser pulses (12) are adjustable in such a way that high-energy electron pulses (20) are emitted from the irradiated at least one electron source on different trajectories (20,28,60,62) through the medium volume (22) thereby depositing their dose in the medium volume (22) according to a provided pattern.
