Digital Breast Tomosynthesis (DBT) is a novel imaging technology to improve early breast cancer detection. It provides three-dimensional information of the breast to overcome the critical issues of overlapping anatomical structures of the breast. Among current available DBT reconstruction algorithms, Maximum Likelihood Expectation-Maximisation (MLEM) is a time-consuming iterative method to reco...

As a breast-imaging technique, digital breast tomosynthesis has great potential to improve the diagnosis of early breast cancer over mammography. Ray-tracing-based reconstruction algorithms, such as ray-tracing back projection, maximum-likelihood expectation maximization (MLEM), ordered-subset MLEM (OS-MLEM), and simultaneous algebraic reconstruction technique (SART), have been developed as rec...

Desmoid tumor of the breast is a rare benign entity that usually is mistaken for carcinoma clinically and radiologically. We report two cases of desmoid tumor of the breast detected by mammography screening using digital breast tomosynthesis (DBT). The larger tumor was detected at both full-field digital mammography (FFDM) and DBT. The smaller desmoid tumor, however, was identified only at tomo...

Abstract Background Tomosynthesis is a recent advancement of full-field digital mammography involves transforming two-dimensional (2D) breast images into three dimensions (3D) images. It reduces the adverse effect tissue superimposition on conventional 2D- mammography, therefore having high potential enhancing identification and assessment asymmetric densities. The aim study was to assess compa...

This paper aims first at implementing two algorithms to extract Region Of Interest (ROI) from 2D (mammography) and 3D images (tomosynthesis) so that to gather ROI databases and second, at analyzing anisotropy of these images textures using an anisotropic fractional Brownian field to check whether the model being studied helps apprehend the breast anisotropy. This analysis includes the estimatio...

August 01, 2007 | Musculoskeletal Imaging [1], Vendors [2] Although the roots of traditional geometric x-ray tomography date back to the 1930s, the technique was not practical at that time because image receptors could not provide large-area dynamic scanning. The technique, renamed tomosynthesis in the 1970s, acquired only one imaging section at a time, requiring additional time and radiation d...

Despite uncertainties with the use of digital breast tomosynthesis (DBT), also called 3D mammography, clinical interest is increasing. Some researchers and patient advocacy groups are promoting its ability to improve breast cancer screenings. Preliminary studies suggest that tomosynthesis has increased specificity and sensitivity over 2D digital mammography (DM), and therefore reduced recall an...

Multiple clinical studies have demonstrated that the use of screening mammography reduces mortality from breast cancer. 2, 3 The efficacy of mammography depends upon the ability to identify cancers based on the differing absorption of x-rays in cancerous tissue compared to adipose and glandular tissue. In mammography cancers often appear ‘white’, similar to normal glandular tissue, making cance...

Abstract Background Breast cancer is considered the most serious lesion among different breast lesions. Mammography corner stone for screening detection of cancer. It has been modified to digital mammography (DM) and then tomosynthesis (DBT). Tomosynthesis an emerging technique diagnosis The aim this study interrogate whether addition DBT DM helps in better characterization Methods This a prosp...

Planar 2D X-ray mammography is the most common screening technique used for breast cancer detection. Digital breast tomosynthesis (DBT) is a new and emerging technology that overcomes some of the limitations of conventional planar imaging. However, it is important to understand the impact of these two modalities on cancer detection rates and patient recall. Since it is difficult to adequately e...
