Plate 77.—Authors duplicate of the original Mackensie-Davidson Cross-Thread Localizer.The mirror below reflects up the light through the negative on the levelled glass plate. Thepointer and vertical scale are seen on the left. The mouse-shaped weights end in needles holdingthe threads. The cross-bar with its millimetre scale can be set at any distance from the baseand must be the distance from anode to film when the negative was made. The plumb linesuspends a lead pointer at a height above the plate. The dotted lines, equidistant from thecentre, start from the two foci of X-rays in the exposure. They cross at the end of theplummet and end at the two shadows on the negative. Simply measure the distance fromthe plate to the crossing of the threads, and we have the depth of the body from the surfaceof the tissues that was on the film of the radiograph. First make a proper double radiographand the rest is simnle. See full directions in text. METHODS OF LOCALIZATION 233 Method of taking
