Field-emission x-ray source arrays have been studied for both tomosynthesis and CT applications, however these arrays tend to have limited output. We propose the use of multi-source x-ray arrays using thermionic cathodes, contained within a single va

Attention to matters of safety is important in any imaging facility. In the context of low- and middle-income countries, limited resources may complicate the attempt to set up and operate an imaging facility with the highest standards of safety, but

Purpose: The authors previously introduced a methodology to generate a realistic three-dimensional (3D), high-resolution, computer-simulated breast phantom based on empirical data. One of the key components of such a phantom is that it provides a mea
