Accurate Radiographic Stereotypes

Once there is a lead as to the possible identity of the victim, and other methods of identification ruled out, radiographic identification begins. However, before the comparison can begin, suitable antemortem radiographs of the presumed victim must be located. Because of the increased use of radiographs as a diagnostic tool, the chances of locating an antemortem image for comparison are high (Christensen & Anderson, 2013). Next, a radiographic image of the skeletal remains is taken ensuring that the scope, orientation, and magnification is similar to that of the antemortem image (Christensen, et. al, 2014). Accurate radiographic identification depends on the similarity of the antemortem and postmortem radiographic films (Kahana & Hiss, 1997).
Finally, the images are compared by visual inspection, either side-by-side or by superimposing the images to look for consistencies and inconsistencies (Christensen & Anderson., 2014; Kahana & Hiss, 1997). Figure 2 shows an example of a correct match of hand radiographs using side-by-side comparison. The arrows indicate corresponding features between the two radiographs. In both cases, details of matching bone trabecular patterns are indicated (Koot, et al., 2005).
