Abstract:
1. Device for manipulating a product and for processing images in order to obtain virtual tomographic sections of the product, comprising: a radioscopy installation comprising a source of radiation of sufficient power to pass through the product, a radiation-sensitive luminescent screen, a manipulator for displacement of the product interposed between the radiation source and the luminescent screen, and a camera for acquisition of radioscopic images formed on the screen, wherein the manipulator is an elevating table having mobility in two crossed directions for the displacement of the product in two directions of a horizontal plane said elevating table being controlled by a terminal for centering the product with respect to a detector formed by the screen and the camera, said device further comprising an assembly which is separately removable from the radioscopy installation, said assembly comprising: a means for displacement of the product in rotation about an axis perpendicular to the tomographic sectional plane to be obtained, fixed on the manipulator, a unit for control of the displacement of the product making it possible to turn the product about the axis of rotation with highly precise angular positioning, a unit for acquisition and processing of images having automatic means for acquisition and storage of radioscopic images of the product, during displacement of the product in rotation, which are connected to the camera and to the unit for control of the displacement of the product in rotation and automatic calculating means for the processing of the radioscopic images in digital form and the construction of tomographic sections using an algorithm for calculation and marking of the position of the axis of rotation of the product.
