Brief description of the control non-destructive simultaneous radiographic data acquisition and clinical tomographic.

摘要

The device comprises a source assembly - detector (2 - 6) of x or gamma radiation, a support (16) of an object placed between the source and the detector, the means (17) in order to ensure at least a relative movement of rotation of the support with respect to the source assembly - detector, the detector is a two-dimensional detector delivering for each point of each projection through an analog signal proportional to the quantity of radiation transmitted by the object (4), a converter (22) of the digital analog - in order to convert the signals from the detector in the digital data, a first memory (28) for storing the digital data, a system (30) for extracting and accumulation of a part of the stored data, corresponding to at least one zone particular to control of the object, a second memory (32) for storing the chinese obtained from the data selected and cumulated and a system for processing these chinese to reconstruct the tomographic cross-sections.
