Abstract

305,322. Hezlet, R. K.., Pullin, V. E. A., and Warren, A. G. Dec. 3, 1927. R÷ntgen-ray apparatus. - A double grid or lattice diaphragm for eliminating secondary radiations comprises two groups of slats crossing each other and forming a curved structure. The diaphragm is adapted to be moved along an arc whose centre is approximately the focal spot of the X-ray tube in order to prevent the formation of an image of the grid on the plate or film. In the form, shown, two groups of slats a, b are slotted at c and d so as to interfit and form a self-supporting structure, but they may be mounted in a frame e movable on the curved rails h. The slats may have the same outline and lie in planes having a common point of intersection at the X-ray tube. -
