ABSTRACT:
A diagnostic technique to histologically detect malignancy and other tissue properties is performed by pressing a solid tissue sample between a pair of planar parallel plates transparent to ultraviolet light to a fraction of the original thickness of the sample and by subsequently passing focused ultraviolet light therethrough. The ultraviolet light is passed transversely to the planar glass plates and the emerging angularly distributed light is analyzed to determine a dignity parameter of the sample containing diagnostic information. In addition, a density parameter is obtained as a function of the portion of the ultraviolet light passing through the sample along the optical axis of the focused light. A diagnosis is obtained on the basis of the relationship between the dignity parameter and the density parameter.
