Dose reduction in xeroradiography of the breast. 1977

W Van De Riet, and J N 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.

D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).
