Abstract:
A method for determining a three-dimensional image data set from a plurality of two-dimensional projection images of an object under examination applies at least one morphological operation to each projection image in order to provide a processing image associated with the respective projection image. At least one respective imaging segment is segmented, in which a highly absorbent region is mapped, depending on the associated processing image, and a respective mask image is generated in which pixels belonging to the imaging segment are marked. An associated synthetic image for each projection image is determined, the image data of which within the imaging segment is set to predetermined values. The projection images and the synthetic images are separately filtered. The three-dimensional image data set is determined by backprojecting the mask images to determine a mask value for each voxel of the image data set.

Claim (Index 1):
A method for determining a three-dimensional image data set from a plurality of two-dimensional projection images of an object under examination, the method comprising the following steps:\n applying at least one morphological operation to each projection image in order to provide a processing image respectively associated with each projection image; segmenting at least one respective imaging segment, in which a highly absorbent region of the object under examination is mapped in a respective projection image, depending on the processing image associated with the projection image, and creating a mask image associated with the respective projection image, in which pixels belonging to the imaging segment are marked; generating an associated synthetic image for each projection image, the image data of which outside the imaging segment corresponds to the image data of the associated projection image and the image data of which within the imaging segment is set to predetermined values; separately filtering the projection images and the synthetic images; determining the three-dimensional image data set by backprojecting the mask images in order to determine a mask value for each voxel of the image data set, wherein the image data of the respective voxel are determined by a backprojection of the relevant pixels of the filtered projection images when a selection condition dependent on the mask value of the voxel is satisfied, and by a backprojection of the relevant pixels of the filtered synthetic images when the selection condition is not satisfied.
