A REVIEW OF DIGITAL BREAST TOMOSYNTHESIS HARD-WARE TECHNIQUES

摘要

Digital Mammography (DM) technique is a well-rooted mode of imaging for early breast cancer detection and diagnosis. After the introduction of digital imaging in the field of radiology, several progressive meth-odologies have been developed, specifically tomographic imaging methodologies that are capable of cap-turing intricate details. The three dimensional (3D) Digital Breast Tomosynthesis (DBT) is one of such methodologies which has witnessed extensive penetration in clinics and possesses the capabilities to replace DM for the screening of breast cancer in the future. A lot of pre-acquisition processes of DBT influence its performance clinically. Therefore, this research focuses on the comprehensive review of the DBT system hardware design, the X-ray supply geometry optimization, radiation dose for breast glandular tissue, X-ray image scatter and breast compression minimization.
