通过 X 射线暗场成像 (DFI) 和明场成像 (BFI) 测试了完整人类手指和膝盖关节软骨可见度的角度依赖性。这些标本用福尔马林固定。作为初步结果，不仅通过 DFI，而且通过角度分析晶体的恰好布拉格角周围的伪 DFI 和 BFI，都获得了良好的关节软骨对比度。这可能表明，不仅在布拉格角而且在其周围使用 DFI 和 BFI 对于临床目的是有用的。
Angular dependence of visibility at articular cartilage of an intact human finger and knee by X-ray dark-field imaging (DFI) and bright-field imaging (BFI) was tested. These specimens were fixed by formalin. Good contrast of the articular cartilage has been obtained, as a preliminary result, not only by DFI but also by pseudo-DFI and BFI around the just Bragg angle of the angular analyzing crystal. This may indicate that it is useful for clinical purpose to use both DFI and BFI not only at just Bragg angle but also around it.
