Breast compression is applied in mammography as it has several advantages including: (1) reduction of overlapping of breast tissues [1-4]; (2) reduction of scattered radiation and thereby, improves image contrast and reduces radiation dose to the breast [1-3, 5]; and (3) reduction of geometric and motion blurring [1-3].Due to the breast size and elasticity, breast . This manual is intended to guide the development and implementation of your quality control program for digital mammography imaging equipment including detailed responsibilities of the radiologist, technologist and medical physicist. The authors have developed a method for measuring the local thickness of the breast at all points of contact with the compression paddle using optical stereoscopic photogrammetry, which will allow them to characterize paddle surface deformations, deflections and calibration offsets for mammographic units. The 2018 ACR Digital Mammography Quality Control Manual is now available.
