[The quantitative x-ray assessment of dynamic pathological processes].
Two quantitative criteria of assessment of change in tissue density resulting from developing pathology or its therapy were proposed on the basis of densitometric investigations of longitudinal tomograms. These criteria are differential and integral indicators of density change. The first one characterizes change of optical density of blackening of a tomogram at the point, and the second one--along the line of densitometric scanning--can characterize the state of a part or a whole organ in a studied direction.
