Summary:The invention relates to a system and method for tracking at least one anatomic structure by means of an image-registration based tracking procedure using at least one parameter, where the anatomic structure includes a plurality of markers. A parameter setting (6, 7) unit is configured to (i) determine measured positions of the markers in each image of a series of images acquired using an imaging unit (1), (ii) determine calculated positions of the markers on the basis of the images by means of the tracking procedure using a variable value of the at least one parameter and (iii) determine an optimized value of the at least one parameter on the basis of deviations between the measured and calculated positions. Then, the position of the anatomic structure is tracked in further images by means of the tracking procedure using the optimized value of the at least one parameter.
