Histology remains a cornerstone of medical diagnostics. By cutting tissue into ultrathin slices, staining it and examining it under a microscope, clinicians can determine whether tissue is diseased and guide treatment decisions. However, this classical approach is labour-intensive and inherently two-dimensional, disrupting the spatial structure of the tissue in the process.
Researchers are therefore exploring virtual histology: high-resolution, three-dimensional X-ray imaging that allows tissue to be examined intact. X-rays can penetrate samples several centimetres thick, enabling full-volume analysis and inspection from any angle. Yet until now, one major limitation remained: unlike conventional histology, X-ray images are monochrome, making it impossible to distinguish stained structures from surrounding tissue.
