Abstract

313,490. Rona, A. June 12, 1928, [Convention date]. R÷ntgen-ray apparatus. - In making a radiograph of a tooth on a sensitive film inside the mouth, a curved bar 4, bearing eight pins 5, set to indicate the direction of the principal ray for the tooth corresponding to each pin, is laid against the jaw. Bars are provided for left and right halves of the upper and lower jaws, and are supported interchangeably, e.g. by a ball joint 6 in a jointed stand 7, 8, 9.
