Which Phantom Is Better for Assessing the Image Quality in Full-Field Digital Mammography?: American College of Radiology Accreditation Phantom versus Digital Mammography Accreditation Phantom

OBJECTIVE To compare between the American College of Radiology (ACR) accreditation phantom and digital mammography accreditation phantom in assessing the image quality in full-field digital mammography (FFDM). MATERIALS AND METHODS In each week throughout the 42-week study, we obtained phantom images using both the ACR accreditation phantom and the digital mammography accreditation phantom, a...

American College of Radiology Mammography Accreditation Program.

The American College of Radiology Mammography Accreditation Program.

This article discusses the background, goals, criteria, current results, impact, and future directions of the American College of Radiology's (ACR's) Mammography Accreditation Program. To date, approximately one half of the mammographic units in the United States have voluntarily applied for accreditation through the ACR program, with approximately one quarter of the units in the United States ...

Dose Reduction in Automatic Optimization Parameter of Full Field Digital Mammography: Breast Phantom Study

PURPOSE We evaluated the impact of three automatic optimization of parameters (AOP) modes of digital mammography on the dose and image quality. METHODS Computerized Imaging Reference Systems phantoms were used. A total of 12 phantoms with different thickness and glandularity were imaged. We analyzed the average glandular dose (AGD) and entrance surface exposure (ESE) of 12 phantoms imaged by ...

Digital breast tomosynthesis (DBT) versus full field digital mammography (FFDM): comparison of a system performance using a contrast detail phantom

To evaluate performance (image signal to noise ratio) of a digital mammographic system working in 2D planar versus tomosynthesis modality, a contrast detail phantom was developed embedding 1 cm plexyglas, including 49 holes of different diameter and depth, between two layers containing a breast simulating material. The acquisition protocol included 15 low dose projections (reconstructed 1mm-thi...
