Abstract:
1. Device for an adjustment of an anti-scattering grid (G) of a radiological equipment to different focal lengths (f 1 f 2 ) that said equipment can provide, characterized in that it includes a first pressing member (P) located at a first end of the device and a second identical pressing member (P) located at an opposite end of the device, both said pressing members (P) being mobile in the direction transverse with respect to the plane of the grid (G), which is arranged and restrained between said pressing members (P) and a pair of identical corresponding underlying contrast members (C) located respectively under said first and second pressing members (P), and in that each pair of pressing members (P) and contrast members (C) has a convex/concave profile corresponding to the locus of the local deformations (d, d′, . . . ), calculated point by point with a suitable spatial resolution, necessary to adjust the orientation of the segments of the grid (G) when adjusting the grid (G) to go from a first focal length (f 1 ) taken as a reference to a second focal length (f 2 ).
