A New Automated Way to Measure Polyethylene Wear in THA Using a High Resolution CT Scanner: Method and Analysis

Figure 7

The calculated CupHeadSeparation plotted against the expected CupHeadSeparation from Table 1, for scan series one and two (both trials). Lines are drawn at the exact expected value and at ±0.1 mm demonstrating the data were within 0.1 mm of the expected distance.
