Abstract:
1. A method for dentomaxillofacial X-ray imaging comprising: providing an X-ray beam having a first radiation spectrum and a flat cross-sectional form towards a predetermined dentomaxillofacial area of a patient; arranging an image receptor in a carrier positioned outside the head of a patient, said image receptor being transversal to said X-ray beam; while radiating said image receptor with said X-ray beam through said dentomaxillofacial area: moving said X-ray beam and said carrier with said image receptor in a first rotational or linear direction, providing an X-ray beam having a second radiation spectrum and the flat cross-sectional form towards said predetermined dentomaxillofacial area of the patient; utilizing said image receptor arranged in said carrier outside the head of the patient; while radiating said image receptor with said X-ray beam having a second radiation spectrum: moving said X-ray beam and said carrier with the image receptor in a second rotational or linear direction that is opposite to said first direction, subtracting said first intensity values and said second intensity values from each other, whereupon a resultant image is formed; and providing the resultant image as such or after processing for further use.
