A device for measuring the grade of absorption of radiation in a three-dimensional object.

摘要

P in the device according to the invention, the image of the body to be examined is reproduced on the basis of two groups of positions of the source of radiation. Each group of positions is located on an arc of circle around the axis of rotation of the assembly member of the radiation detection device, and the part of the two arcs of circle determines the size of the zone examined for which the image reconstruction of absorption. The device (s) (s) of detection is (are) placed (s) between the two arcs of circle. / p & & p & application to the apparatus of the tomographic. / p
