Abstract
A cassette for holding sheet film during exposure to x-radiation includes first and second hingedly connected panels. Both panels are curved substantially cylindrically when in the open condition, with the axes of the cylinders parallel to the hinge line and with the convexities facing one another. One of the panels is formed of carbon fiber reinforced plastics material and additionally, in some regions, deviates from the cylindrical by being curved towards the other panel, when in the open condition. Thus, while the cylindrical curvature is convex towards the other panel the regions of curvature out of the cylindrical exhibit some concavity towards the other panel. Such a panel improves the contact of the intensifying screens with the film and also the integrity of the light seal at the periphery of the cassette.
