Evaluation of X-ray dark-field imaging in visualization of nearly clinical articular cartilage

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.
