Abstract:
1. A tomography apparatus comprising: means for support of an object to be subjected to tomography; means for providing and carrying a source of radiation having a focal spot; means for detecting the radiation; and means for shifting the means for providing a source of radiation along a path relative to the means for support, the means for shifting comprising means for varying the speed of the focal spot as a function of the position of the focal spot relative to the means for support, wherein the means for shifting provides for the acceleration of the focal spot relative to the means for support is continuous and provides for the speed of the focal spot relative to the means for support is continuous and provides for a multiplicity of positions distributed on the path, the number of which is greater than or equal to three, and provides for the speed passing each time through a minimum value at a point, and provides for each exposure of the object to the radiation is made for a duration in which the speed of the focal spot is minimal.
