Abstract

A hand-guided modality is to be positioned with little effort or radiation load. To this end an object model is created from 3D data of an object. Moreover, a surface model of the object is created. Both models are registered to one another. Depending on a target region in the object model, a start position and a start orientation of the hand-guided modality are calculated. Moreover, a target image of the object is calculated on the basis of the object model, the target region and also the start position and start orientation. A real ultrasound image is further acquired from the start position and start orientation. A repositioning and/or re-orientation of the hand-guided modality is undertaken on the basis of a deviation between the ultrasound image and the target image.
