Figure 4-24. For the flashing method, identifying information is first placed on a three-
c. Lead Marker. Another method of film identification is to assemble all the
information on an aluminum tab or strip using lead numerals and letters. The tabs or
strips are then taped to the cassette before exposure. (In this case, a number rather
than his full name usually identifies the patient.) This method is used in the field. The
lead marker is used to identify the corresponding side or area being demonstrated. It
consists of an R or an L and a technologists's identification (I.D.) number or initials
(figures 4-25 and 4-26). Other lead markers may be needed for certain procedures
(time interval, uptight, with/without weights, and open/closed lead markers). An
example is shown in figure 4-27.
Figure 4-25. The lead marker, about the size of a razor blade, has a left LM and the
technologist's number for accountability purposes.
