Dose reduction in xeroradiography of the breast
W Van De Riet
and
JN Wolfe
In a study of the effects of beam filtration on the entrance exposures encountered in xeroradiography of the breast, it was found that increasing the total filtration to 3.2 mm of aluminum reduced entrance exposures by a factor of three compared to the xeroradiographic techniques without added filtration. Changes in the processing parameters were found to restore much of the lost contrast observed when filtration was increased, resulting in clinically acceptable mammograms at reduced entrance exposures.
