CT tissue images can now be virtually stained in 3D

Article excerpt

Rudolf Virchow fundamentally changed medicine when he formulated his cell theory of disease in the 19th century: Diseases do not arise inexplicably within the organism, but rather in specific cells and tissues. To this day, pathology, the study of disease processes, is essentially based on the time-consuming examination of thin tissue sections, which are stained and then viewed under a microscope.
