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 . advent of digital mammography, efforts were made to revise quality assurance guidelines for mammography and adapt them in line with technological advancements. A correctly performed CC projection may show the pectoral muscle on the posterior edge of the breast, indicating that the breast has been positioned as far forward as . Thesynthetic 2D images and 3D slices are reviewed together to make clinical decisions ordiagnoses part of the Genius 3DMammography screening exam. As a suggested mammographic guideline, compression pressures of approximately 10kPa aid in image acquisition reproducibility both within and between women; pain levels decrease, with minimal variations to breast thickness, AGD and image quality. Mammography: Part III. Conclusions: After BCT, women have hardly any choice in avoiding an annual follow-up mammogram. Medical Image Analysis, 1:119, 1996.

For mammography machines, the following parameters must be controlled: 1.anode voltage; 2.exposure time; 3.the total thickness of the filter; 4.Kerma in the air; 5.radiation output; 6.coincidence of light and radiation fields; 7.automatic exposure control system (AUE); 8.compression and compression thickness; 9.image settings (Contrast and . A method of modelling the thickness at the breast periphery is presented with examples of the thickness maps generated. A first order thickness correction is employed to correct for inaccuracy in the compression thickness indicator of the mammography units. Neither technique allows retrospective estimation of thickness. In the control arm, mammography will be performed as normal clinical practice, with compression controlled by the radiographer. The estimated increase in thickness is +6.4% for BCT breasts. Compression Thickness is a monthly procedure and measures that the compression is within tolerance, and Compression Force is performed every six months to ensure adequate compression is maintained throughout the scan. installation of a new processor, replacement of an x-ray tube); however, your medical physicist must conduct a Mammography Equipment Evaluation (and all applicable tests must pass) before you may use the unit to examine patients.
