Radiostereometric analysis is a highly accurate imaging technique. A recent advance in radiostereometric analysis is the use of flat panel digital radiography, which provides the opportunity for quick analysis using radiostereometric analysis. However, such a setup is expensive. Using large cassettes for small joints could minimize the cost. In this article, we investigated the influence of cassette size for small joint examinations with a biplanar radiostereometric analysis setup. Our results indicated that there is no significant difference in the precision when using large cassettes over small cassettes, whether or not imaging magnification is applied.
放射立体分析是一种高度精确的成像技术。放射立体分析的一项最新进展是使用平板数字射线摄影，这为利用放射立体分析进行快速分析提供了机会。然而，这样的装置成本高昂。使用大暗盒进行小关节检查可以将成本降至最低。在本文中，我们使用双平面放射立体分析装置研究了暗盒尺寸对小关节检查的影响。我们的结果表明，无论是否应用成像放大，使用大暗盒与小暗盒时精度没有显著差异。
