The present invention relates to image acquisition technology. In particular, the present invention relates to tracking of an object of interest in ultrasound image information. For interventional procedures, an object of interest, e.g. the tool by which a procedure is performed, is depicted in image information acquired by a certain imaging modality. However, e.g. during transcatheter intracardiac procedures, tools are employed, which are rather narrow objects that may experience substantive passive motion due to heartbeat and blood flow as well as active motion due to the interventionist steering the tool. The present invention to allows steering two-dimensional ultrasound image acquisition, in particular steering of an imaging plane of an ultrasound image acquisition device, so that an object of interest remains visible in the acquired images, in particular without continuous readjustment of imaging parameters. Accordingly, a method for ultrasound image acquisition, in particular for tracking an object of interest in ultrasound image information, is provided comprising receiving (12) X-ray image information (40) and ultrasound image information (42), detecting (14) an object of interest (36) in the X-ray image information (40) and steering (16) two-dimensional ultrasound image acquisition such that the object of interest (36) is within a first ultrasound image plane (42). |
