Both hands of theexaminer are free, as either a mounted screen or the fluoroscope isheld securely in place. No particular preliminary posing of the tubeis required. As all parts of the frame are both separately and collec-tively adjustable at any height, angle, or position, it can be sightedtoward the focus of a tube situated anywhere, just as a rifle can besighted at any target. This independence of an exact position forthe tube is a great convenience to the operator. The actual setting ofthe adjustments of the markers in the frame is almost as simple assetting the hands of a watch, and can be almost as quickly done. Ofcourse an object-lesson demonstrates this facility far better than canbe told in print. Directions for Use on an Examining-Table.—With the patient re-cumbent, examinations require that the frame be lifted from the. Plate G1.—This instruction plate shows the Authors Examining Frame with its adjusta-ble wooden floor used to level a part and support it during examination or localization. Turn-ing the long spiral screws raises and lowers the upper shelf on which the part rests. Note theexact register of the two vertical guides in the axis of the rays. The central radiation coin-cides with the point where the horizontal and vertical guides intersect and the fracture, lesion;or bullet t
