Influence of Image Reconstruction Method on Image Quality in Digital Breast Tomosynthesis

Iterative Breast Tomosynthesis Image Reconstruction

In digital tomosynthesis imaging, multiple projections of an object are obtained along a small range of di↵erent incident angles in order to reconstruct a pseudo-3D representation of the object. In this paper we discuss a mathematical model for polyenergetic digital breast to-mosynthesis image reconstruction that explicitly takes into account various materials composing the object and the polye...

Enhancing the image quality of digital breast tomosynthesis

Quantitative image quality measurements of a digital breast tomosynthesis system.

PURPOSE The aim of this study was to measure the image quality of a digital breast tomosynthesis (DBT) system quantitatively. MATERIALS AND METHODS The signal transfer property (STP), modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE) of the Hologic Selenia Dimensions breast tomosynthesis system were measured according to established methods...

Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...

Statistical iterative reconstruction to improve image quality for digital breast tomosynthesis.

PURPOSE Digital breast tomosynthesis (DBT) is a novel modality with the potential to improve early detection of breast cancer by providing three-dimensional (3D) imaging with a low radiation dose. 3D image reconstruction presents some challenges: cone-beam and flat-panel geometry, and highly incomplete sampling. A promising means of overcome these challenges is statistical iterative reconstruct...
