Abstract: There is provided a computer-implemented method for creating a panoramic radiographic image (600) of an object under examination (108). The method comprises: obtaining a stitching sequence comprising overlapping partial images of the object under examination; obtaining (401) data separating a marker region of the stitching sequence from an object region, the marker region depicting a stitching marker usable for image registration; performing a first stitching operation, comprising performing a first image registration process on the stitching sequence with respect to a marker plane and reconstructing (403A) therefrom a marker composite image (502); performing a second stitching operation, comprising performing a second image registration process on the stitching sequence with respect to an object plane and reconstructing (403B) therefrom an object composite image (504); rescaling (404) at least one of the marker region of the marker composite image (502) and the object region of the object composite image (504) to account for an object-marker distance, wherein the rescaling comprises applying separate scaling factors to the marker region and the object region such that the said regions exhibit the same scale following the rescaling; selecting image regions for inclusion in the panoramic radiographic image, comprising selecting (402A) the marker region of the marker composite image and selecting (402B) the object region of the object composite image; and combining (405) the selected image regions to form the panoramic radiographic image.

Abstract: The present invention relates to acquisition of medical image information of an object. In order to provide a user-friendly alignment of X-ray tube (18) and a detector (24), optionally combined with an anti-scatter grid, an alignment arrangement (200) is proposed, which comprises a tube attachment (26) with a first light projection device (28) and a detector attachment (34) with a second light projection device (36). The first and second light projection devices each generate a light pattern (30, 38) on a projection surface (32). The tube attachment (26) and the detector attachment (34) can be brought into a correct spatial arrangement relative to each other by bringing the first light pattern in a predetermined spatial relation with the second light pattern (38) on the projection surface.
