Abstract: The invention relates to a data processing method of determining a positional transformation (T, M) for correcting the registration of an anatomical body part with a medical imaging apparatus, the method being executed by a computer and comprising the following steps: a) acquiring initial body part position data comprising initial body part position information describing an initial relative position (1) between the medical imaging apparatus and the anatomical body part; b) acquiring, from the medical imaging apparatus, body part medical image data comprising body part medical image information describing an image of the anatomical body part; c) acquiring, based on the body part medical imaging data, actual body part position data comprising actual body part position information describing an actual relative position (2, 4) between the anatomical body part and the medical imaging apparatus; d) determining, based on the actual body part position data and the initial body part position data, body part position transformation data comprising body part position transformation information describing a transformation (T, M) between the initial relative position (1) between the anatomical body part and the medical imaging apparatus, and the actual relative position (2, 4) between the anatomical body part and the medical imaging apparatus.

Abstract: Disclosed is a computer-implemented medical data processing method for determining an orientation of an electrode, the electrode being configured for electrically stimulating an anatomical structure of a patient and comprising a rotational orientation marker, the method comprising executing, on at least one processor of at least one computer, steps of: a) acquiring (S1.1), at the at least one processor, rotational image data describing two-dimensional medical images of the anatomical structure and the electrode, the two-dimensional medical images having been taken with a two-dimensional medical imaging apparatus during rotation of the medical imaging apparatus relative to the anatomical structure, the rotational image data further describing, for each of the two-dimensional medical images, an imaging perspective relative to the anatomical structure associated with the respective two-dimensional medical image; b) determining (S1.2), by the at least one processor and based on the rotational image data, rotational orientation data describing the rotational orientation of the electrode in the reference system of the two-dimensional medical images; c) acquiring (S1.3), at the at least one processor, tomographic image data describing a set of tomographic medical images of the anatomical structure; d) determining (S1.4), by the at least one processor and based on the rotational image data and the tomographic image data and the rotational orientation data, electrode orientation data describing a rotational orientation of the electrode in a reference system of the tomographic medical image data.

Abstract: Disclosed is a computer-implemented method for determining an orientation of an electrode using acquired two-dimensional rotational images taken while the two-dimensional imaging apparatus is rotated about the patient, and acquired three dimensional tomographic images of the anatomical structure. The electrode orientation is determined in the three-dimensional reference system of the tomographic imaging apparatus.
