[The effect of scatter on film quality in mammography (author's transl)].
The proportion of total radiation during mammography due to scatter was measured by film densitometry, and was found to average 44% (N = 16). The relationship between the geometry of the scattering object and the distribution of scatter was investigated experimentally. The relationship between gradation, amount of scatter and maximal resolution, as well as contrast, are discussed. The usual collimation and breast compression do not result in any significant reduction of scatter. The use of grids is described, but the technical problems involved have not yet been solved.
