Claim:
1. A method for operating a computed tomograph, the method comprising: penetrating an object with an X-ray from a plurality of positions; effecting, at each position of the plurality of positions, a deposition of an individual dose of radiation in at least one part of the object, wherein the individual doses add up to a total dose of radiation; and generating an image signal, via a detector, at each position of the plurality of positions, by way of a transmitted intensity of the X-ray, wherein a plurality of exposure parameters, which influence an image quality of the image signal, are set individually for each position of the plurality of positions, wherein the exposure parameters for each position of the plurality of positions are selected such that a respective product of the individual dose and a measure for the image quality is identical for each position of the plurality of positions, wherein individual doses for respective positions of the plurality of positions are configured to be: (1) raised when a raising provides a greater improvement in the image quality than in another position, or (2) lowered when a lowering provides a smaller deterioration in the image quality than in another position, and wherein the total dose of radiation does not exceed a predetermined value such than when an individual dose is raised in a specific position, at least one additional individual dose is lowered in at least one separate position.
