Tomographic mammography using a limited number of low-dose cone-beam projection images.
A method is described for using a limited number (typically 10-50) of low-dose radiographs to reconstruct the three-dimensional (3D) distribution of x-ray attenuation in the breast. The method usesExpand

A calibration approach to glandular tissue composition estimation in digital mammography.
The healthy breast is almost entirely composed of a mixture of fatty, epithelial, and stromal tissues which can be grouped into two distinctly attenuating tissue types: fatty and glandular. Further,Expand

Investigation of Different PV Distributions in Digital Breast Tomosynthesis (DBT) Mammography
TLDR
We investigated the effect of different distributions of projection-view (PV) images that included different angular range and angular spacing on the reconstruction image quality. Expand

Optimization of slice sensitivity profile for radiographic tomosynthesis.
Similar to other tomographic imaging modalities, the slice sensitivity profile (SSP) is an important image quality metric for radiographic tomosynthesis. In this study, the relationship between theExpand

Computed tomography part I: Introduction and industrial applications
X-ray computed tomography (CT) provides quantitative, readily interpretable data and enables the inspection of structures that are not amenable to any other nondestructive evaluation technique. As aExpand

Image quality of microcalcifications in digital breast tomosynthesis: effects of projection-view distributions.
PURPOSE To analyze the effects of projection-view (PV) distribution on the contrast and spatial blurring of microcalcifications on the tomosynthesized slices (X-Y plane) and along the depth (Z)Expand

High-speed large angle mammography tomosynthesis system
TLDR
A new mammography tomosynthesis prototype system that acquires 21 projection images over a 60 degree angular range in approximately 8 seconds has been developed and characterized. Expand
