er. The localizer will perform its work in almost any position in whicha part can be placed in it, and the operator may choose that which ismost convenient. It is best adapted to the cranium and extremities.If a round bullet or object is localized very exactly, the ball of thedepthing-rod will indicate the perpendicular of the anterior surfaceof the bullet. The hody of the bullet will lie behind the plane ofthis perpendicular. If an elongated object is localized, the frame canbe shifted to show the longest axis of pin, needle, bullet, or fragmentof bone, and both ends and the connecting line between them can bemapped out automatically by the depthing-rod and the level finders.No calculation or figuring at any time is required. In practice to become familiar with the device the beginner maybury small pieces of metal in irregular blocks of wood, odd shapedmasses of bread, meat, or any convenient material. After makingthe shadow travel to the side post out of the direct axis of the rays.

Plate 65.—Authors One-Minute Localizer. Second Stef). With all parts held as beforesimply give the entire frame, with screen and arm, a slight lateral turn to either right or left.Stop whea the bullet has travelled over to the vertical guide. With the right hand slide thedepthing rod straight back on its guiding rod till its marking pin is exactly over the shadowof the bullet on the vertical guide. The bullet is located by this simple method without anydivergence or distortion whatever and in a single moment. Hold the part still in the frame,unclamp the fluoroscope, mark the point of the front marker on the skin and mark the skinwhere the pin of the depthing rod touches it. When the two cross sections are thus markedthe surgeon will find the bullet at the intersecting point without deviation. Study these platesin connection with the descriptive text.
