Abstract: A method for correcting a result (5), detected using a detector (2), of a radiation-physics process pertaining to a radiation-source (6) by an artificial neural network (4) is provided. The artificial neural network (4) was initially trained with synthetic data pairs (8), and the synthetic data pairs (8) include a first, in particular synthetic, datum (9) and a second, in particular synthetic, datum (10). The data (9, 10) of a data pair (8) differ by a detector-specific transformation (11) that is uniform for all data pairs (8). A detection arrangement as well as a phantom for use with such a detection arrangement are also provided.

Abstract: A radiotherapeutic detector device (14) comprising a detector arrangement (1) which has more than two carriers (2) which are arranged crosswise, and a detector field (7) is arranged on each carrier (2).

Abstract: A measurement system for use in radiation therapy, for example for measuring radiation sources, in particular for a water phantom. The water phantom has a water container and a measurement system, on which at least one holder for a radiation detector is arranged. The holder can be moved within the water container along at least one movement axis, with a control unit being present, which accepts and executes commands for controlling the movement axis. A virtual coordinate system which is aligned to the water surface is defined so that the movement device does not have to be aligned with great complexity. A conversion unit transfers control commands from the virtual coordinate system into the real coordinate system of the movement device so movements of the holder are always parallel and/or perpendicular to the water surface.
