Abstract: The present invention relates to a method for positioning a patient's body part including a target to be depicted by means of an imaging device relative to the imaging device, particularly an irradiation source of a radiation imaging device, that generates a radiation beam directed towards the target, the method being constituted to be executed by a processor of a computer and comprising the following steps:—receiving, at the processor, geometry data describing the geometry of at least one structure located in the field of view of the imaging device;—receiving, at the processor, tracking data describing the spatial location and/or orientation of the at least one structure within the field of view of the imaging device;—determining, with the processor, position data incorporating the geometry data and the tracking data, describing whether the location and/or orientation of the at least one structure with respect to an image trajectory, particularly a radiation beam trajectory through the target is desirable;—determining, with the processor, repositioning data describing a desired location and/or orientation of the at least one structure with respect to the image trajectory, particularly the radiation beam trajectory through the target;—outputting, from the processor, the repositioning data allowing for repositioning of the at least one structure. The present invention further relates to a corresponding computer program and system.

Abstract: The invention relates to a computer-implemented medical data processing method for determining a heartbeat signal describing the heartbeat of a patient in the time domain, the method comprising executing, on a processor of a computer, steps of: a) acquiring, at the processor, acceleration measurement data describing an acceleration in the time domain of an anatomical body part measured on an external surface of the anatomical body part; b) determining, by the processor, component analysis data describing a result of an independent component analysis in the time domain of the acceleration measurement data; c) acquiring, at the processor, heartbeat template data describing template shapes of heartbeat in the time domain; d) determining, by the processor and based on the component analysis data and the heartbeat template data, recurrent shape data describing a recurrence of certain signal shapes in the component analysis data; e) determining, based on the recurrent shape data, heartbeat signal data describing a time series of the heartbeat.

Abstract: A data processing method performed by a computer (2) for determining the structure of a medical implant (12; 18; 20; 22) which is to replace removed tissue in a patient's body, comprising the steps of:—acquiring a 3D dataset which represents remaining tissue (10; 17) which at least partly surrounded the removed tissue before the latter was removed;—determining the required contour of the implant (12; 18; 20; 22) from the 3D dataset;—simulating forces exerted by the remaining tissue (10; 17) on the contour of the implant (12; 18; 20;22); and—determining a structure dataset which represents the structure of the implant (12; 18; 20; 22) such that the implant (12; 18; 20; 22) has the required contour and can absorb the simulated forces.
