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) direction for the same radiation dose in digital breast

Similar to other tomographic imaging modalities, the slice sensitivity profile (SSP) is an important image quality metric for radiographictomosynthesis. In this study, the relationship between the acquisition angular range ( θ ) and the SSP for the

This paper describes work aimed at combining 3D ultrasound with full-field digital mammography via a semi-automatic prototype ultrasound scanning mechanism attached to the digital mammography system gantry. Initial efforts to obtain high x-ray and ul

The z-resolution is an important image quality metric for a tomosynthesis system. The relationship between the acquisition angular range and z-resolution has yet been carefully investigated, mainly due to the lacking of a tomosynthesis system capable

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 a result, CT has become well established as an inspec

Tomosynthesis imaging in chest radiography provides volumetric information with the potential for improved diagnostic value when compared to the standard AP or LAT projections. In this paper we explore the image quality benefits of 2D scanning trajec

We are investigating factors affecting the detection of microcalcifications in digital breast tomography (DBT). In this study, we analyzed the effects of projection-view (PV) distribution on spatial blurring of calcifications on the tomosynthesized s

Digital Breast Tomosynthesis (DBT) Mammography is an emerging technique that has the potential to improve breast cancer detection. In DBT, low-dose mammograms are acquired at a number of projection angles over a limited range and the 3D breast volume

We report on the design of a neutron detector using industry standard 3 He tubes to count delayed neutrons during the interrogation of cargo containers for the presence of Special Nuclear Material (SNM). Simulations of the detector design were run fo

Two mechanisms for MTF dependence on incident x-ray angle are demonstrated by an experimental technique that separates the two phenomena. The dominant effect is that travel of x-ray photons through the scintillator at non-normal incidence involves an
