Patent ID: 7697661

Claim:
A method for obtaining a tomosynthesis image for a more selective detection of radiology signs, comprising: providing an X-ray irradiation dose by means of an X-ray tube for which a direction of the X-ray irradiation dose is oriented at an angle of orientation relative to a body; distributing the orientation of the direction along a path by changing the angle of orientation between two borderline orientations; exposing the body to the X-ray irradiation at each of the orientations; and varying the X-ray irradiation dose produced by the X-ray tube during the exposure as a function of the orientation of the direction relative to the body, wherein the angle of orientation changes with the size of radiology sign, wherein one orientation or one group of orientations is favored relative to the multiplicity of orientations of the path, and wherein the accumulated irradiation dose of the favored orientation or of the favored group of orientations is greater than 5/9th of the total irradiation dose.
