    Abstract: The present invention relates to computer-implemented medical method of verifying an expected deformation of an elastically deformable and actuator-adjusted medical fine-adjustment unit (1), the method comprising executing, on a processor of a computer, the steps of; —acquiring model data describing a model of the fine-adjustment unit (1), the model reflecting deformation properties of the fine-adjustment unit (1); —acquiring actuator data describing an actuator position of at least one actuator coupled to the fine-adjustment unit (1); —determining, based on the model data and the actuator data, target deformation data describing a target deformation of the fine-adjustment unit (1) caused by the at least one actuator at said actuator position; —acquiring actual deformation data describing an actual deformation of the fine-adjustment unit (1) caused by the at least one actuator at said actuator position; —determining, based on the target deformation data and the actual deformation data, verification data describing whether the target deformation corresponds to the actual deformation. The present invention further relates to a corresponding computer program causing a computer to perform such method, and a corresponding system comprising such a computer.

    Abstract: Disclosed is a method for determining a positional pattern of an irradiation unit for irradiating a patient with treatment radiation. Optimal order data describing an order of the irradiation unit positions for which the statistical value is optimal is determined. The optimal order data is determined based on irradiation unit position data describing irradiation unit positions of the irradiation unit for which the imaging device has a free viewing direction onto the position of the patient, position orders data describing all possible orders of the irradiation unit positions for which the imaging device has a free viewing direction onto the position of the patient, and intersection angle data describing a statistical quantity of the intersection angles between free viewing directions of the imaging unit for irradiation unit positions which are immediately subsequent in the order described by the position orders data.

    Abstract: Provided is a data processing method for determining rotation by a marker device of a medical tracking system about its mount. The data processing method includes acquiring a first marker device position dataset which represents a position of the marker device before a movement of the marker device. A second marker device position dataset is acquired which represents the position of the marker device after a movement of the marker device. A marker device displacement dataset is calculated, which represents the displacement of the marker device, from the first and second marker device position datasets. At least one axis of rotation of the marker device displacement dataset is calculated. A determination is made whether or not the marker device is rotated about its mount from the position of the at least one axis of rotation relative to the marker device.
