Abstract: A method for encoding complex-valued signals of a computer-generated hologram into a phase-modulating optical element for the reconstruction of a three-dimensional object, and to a computer program product for encoding complex-valued signals of a computer-generated hologram, and to a holographic display for the reconstruction of a three-dimensional object. The object is to reduce the effort on encoding a complex-valued spatial distribution by an iteration method on the basis of phase encoding, so that the computer-generated hologram resulting therefrom can be represented more rapidly and with the same or an improved reconstruction quality. In particular, the convergence during the iterative optimization is intended to be accelerated. This is achieved by a method in which degrees of freedom of the hologram plane as well as the reconstruction plane are used for optimizing the iteration method for rapid convergence and maximization of the diffraction efficiency in the signal range.

Abstract: A method is disclosed for analyzing image data from a patient after a minimally invasive intervention on a lesion, in particular after a tumor ablation on a tumor, wherein a pre-intervention image dataset showing the lesion and an intra- and/or post-intervention, second image dataset showing the intervention region are analyzed. In at least one embodiment of the method, the method includes deriving attribute data describing attributes of the image data from the image datasets at least in part automatically, the attribute data being usable as input data to an artificial intelligence analysis algorithm trained using training data from other patients, and the training data being associated with a ground truth. The method further includes determining, from the attribute data, change information that describes the change in the lesion and/or in the intervention region as a result of the intervention.
