Abstract
A data processing method for co-registering a medical 3D image dataset and a spatial reference (27), comprising the steps of: acquiring the 3D image dataset, wherein the 3D image dataset represents a medical CT image, a medical MR image or an angiograph of at least a part (20) of a patient and a set of hybrid markers (11); detecting the positions of the hybrid markers (11) in the 3D image dataset so as to obtain a scan matrix representing the arrangement of the set of hybrid markers (11) in the 3D image dataset and the position of the scan matrix in the 3D image dataset; acquiring the positions of the hybrid markers (11) with respect to the spatial reference (27), so as to obtain an image matrix (22a) representing the arrangement of the set of hybrid markers (11) in three-dimensional space and the position of the image matrix (22a) relative to the spatial reference (27); and co-registering the scan matrix and the image matrix (22a).
