The apparatus ( 1 ) comprises an input ( 2 ) for receiving a suitable source image data of an object. The core of the apparatus ( 1 ) is formed by a control unit ( 4 ) which is arranged to load image data from the input ( 2 ) and determine a spatial position and orientation of a portion of the object and to automatically calculate actual parameters ( 4 a) of the imaging geometry based on said position and orientation and using default parameters if the imaging geometry, selected by the control unit ( 4 ) in accordance with the portion of the object. The apparatus ( 1 ) further comprises a storage unit ( 8 ) arranged to store at least one set of default parameters of the imaging geometry, which may be representative of an imaging protocol. The working memory ( 6 ) typically holds the (parts of) image data being processed and the instructions for the suitable image processing means used for processing those parts of the image data. The apparatus ( 1 ) according to the invention comprises a recognition module ( 7 ) arranged to determine a spatial position and orientation of the portion of the object with respect to a coordinate system of an imaging apparatus conceived to use the actual parameters of the imaging geometry provided by the apparatus ( 1 ). When the position and orientation ( 7 a) of the portion of the object with respect to the coordinate system of the data acquisition module is established, the control unit calculates actual parameters ( 4 ) of the imaging geometry based on a suitable matching between the spatial position and orientation ( 7 a) of the portion of the object conceived to be imaged and the default parameters of the imaging geometry ( 3 ). Preferably, the apparatus ( 1 ) further comprises a suitably arranged user interface ( 5 ) for allowing an adjustment of automatically established actual parameters of the imaging geometry by a user Preferably, the output ( 9 ) comprises a result of the automatic planning of the imaging geometry, which may be directly converted into a suitable control signal for the data acquisition module and/or be made available in a suitable form for archiving purposes. The invention further relates to an imaging system, a method and a computer program for automatically generating scan parameters.
