A method for detecting and displaying an introduced in an examination region of a patient medical catheter

A method for detecting and displaying a in an examination region (6) of a patient (7) introduced the medical catheter (14), in particular in the context of a cardiac examination or treatment, comprising the steps of: - using a 3D image data set (10) of the examination region (6) and generating a 3D reconstructed image (12) of the examination zone (6), wherein in a rhythmically or arrhythmic moving examination region (6) for reconstructing the 3D reconstructed image (12) only those image data (10) are used, which are added during a particular phase of movement, which is detected in parallel with the acquisition of the image data (10), wherein during the detection of the position of the catheter (14) also detects the phase of movement and the position data (19 be) recorded only when the scan area is in the same phase of motion in which the 3D reconstructed image (12) is reconstructed; - continuous or discontinuous detection of the spatial position of the tip of the catheter (14) by means of a position detection system (16), wherein in the tip of a position detecting means (15) is integrated; - Presentation of ...
