Technique For Determining A Position of One Or More Imaged Markers In An Image Coordinate System
A method and a device for determining a respective position of one or more markers in a 3D image coordinate system are provided. A plurality of image data sets taken from a 3D volume in which an object and one or more markers are disposed. The 3D volume comprises a central volume containing at least...

| description | A method and a device for determining a respective position of one or more markers in a 3D image coordinate system are provided. A plurality of image data sets taken from a 3D volume in which an object and one or more markers are disposed. The 3D volume comprises a central volume containing at least a portion of the object and further comprises a peripheral volume adjacent to the central volume and containing the one or more markers. The image data sets have been taken from at least one of different positions and different orientations relative to the object. A first subset comprises image data sets that each includes at least one dedicated marker of the one or more markers and a second subset comprises at least one image data set that does not include the at least one dedicated marker. The method further comprises determining, from the image data sets, a position of the at least one dedicated marker in a 3D image coordinate system of a 3D reconstruction of the central volume with the object portion. |
