Phase-contrast digital tomosynthesis
Medical Physics, 2011Phase-contrast (PC) edge enhancement occurs at the boundary between different tissues and is an interference effect that results from the differential phase-shifts that the x-rays acquire while traversing the two tissues. While observable in planar phase-contrast radiographs, the impact of digital tomosynthesis on this edge enhancement effect has not ...

Advances in Digital Breast Tomosynthesis
American Journal of Roentgenology, 2017Digital breast tomosynthesis (DBT) has rapidly emerged as an important new imaging tool that reduces the masking effect of overlapping fibroglandular tissue, thereby improving breast cancer detection. This article will review key features of DBT including technique, clinical implementation, and benign and malignant imaging findings.

Meshless reconstruction technique for digital tomosynthesis
Physics in Medicine & Biology, 2020A novel meshless reconstruction algorithm for digital tomosynthesis (DT) is presented and assessed against experimental data. The algorithm does not require a three-dimensional grid or mesh allocation and performs a slice-by-slice reconstruction where each slice position can be chosen at runtime.

Mammography and Digital Breast Tomosynthesis: Technique
2022The introduction of mammography as a radiographic imaging modality optimized for breast imaging revolutionized breast cancer care. Throughout the decades, conventional, screen-film-based mammography has given way to digital mammography, resulting in many benefits, including a streamlined workflow and improved performance in certain subgroups of ...

Digital tomosynthesis of the pediatric elbow
Pediatric Radiology, 2019Imaging pediatric elbow trauma in the acute setting remains diagnostically challenging given difficult patient positioning, multiple ossification centers of the pediatric elbow, overlapping structures, and complex joint anatomy. Digital tomosynthesis is a technique where the X-ray source travels across a limited arc angle, obtaining a series of low ...

Digital tomosynthesis: technique.
Radiologic clinics of North America, 2014Digital breast tomosynthesis is an extension of digital mammography that produces quasi three-dimensional reconstructed images from a set of low-dose x-ray projections acquired over a limited angular range. The quality of the reconstructed image and the dose to the breast are dependent on the angular range and number of projections, the dose used per ...

Radiologic technology, 2009
Digital breast tomosynthesis (DBT) is a new technology that combines the use of tomography and 3-D reconstruction with breast imaging to improve lesion visibility. Although no DBT equipment yet has been approved by the U.S. Food and Drug Administration, the technology is creating interest in the United States and research on its effectiveness continues
