Method and apparatus for triggering image acquisition in a C-arm system by a rotary encoder

摘要

Method of generating an image of an object by means of an imaging system which has a radiation source that rotates relative to the object about an axis of rotation within a defined rotation angle range, said radiation source projecting radiation onto a radiation detector in order to record projection data, wherein at predefinable relative rotation angle positions of the radiation source a signal projection data is generated, and also apparatus for carrying out this method.
