Introduction
1.1 Product Description
The mammographic unit’s automatic exposure control should be capable of maintaining optical density
within ± 0.15 OD as the voltage is varied from 25 to 35 kVp, and as breast thickness is varied from 2 to 8
cm for each technique. Test images taken of uniform phantoms of varying thicknesses should not differ by
more than 0.30 OD from each other. These tests should be carried out over the kVp range customarily
used by the mammography center.
The Phototimer Consistency Test Tool is available in two materials: acrylic; and, for more accurate
results, breast-tissue-equivalent BR-12 material. Both are supplied in uniform 2.0 cm slabs to produce
thicknesses of 2, 4, 6, and 8 cm.
