One-dimensional (1-D) nanomaterials possess unique shape-dependent phyicochemical
properties and are increasingly recognized as promising materials for nanotechnology. 1-D …

Carbon nanomaterials are a class of low-dimensional materials that have aroused a great
deal of interest in the past 30 years since the spectacular debut of fullerene, the first member …

Mammography is a very well‐established imaging modality for the early detection and
diagnosis of breast cancer. However, since the introduction of digital imaging to the realm of …

A cold cathode X-ray tube was fabricated using a carbon nanotube (CNT) field electron
emitter made by a free-standing CNT film which is composed of a highly packed CNT …

Limited-angle X-ray computed tomography (CT) reconstruction is a typical ill-posed problem.
To recover satisfied reconstructed images with limited-angle CT projections, prior …

Since the discovery of X-rays over a century ago the techniques applied to the engineering
of X-ray sources have remained relatively unchanged. From the inception of thermionic …

We report on a fully vacuum-sealed compact x-ray tube based on focused carbon nanotube
(CNT) field-emission electrons for various radiography applications. The specially designed …

Digital breast tomosynthesis (DBT) has become a well-established breast imaging
technique, whose performance has been investigated in many clinical studies, including a …

Purpose Stationary computed tomography (s‐CT) conceptually offers several advantages
over existing rotating gantry‐based CT. Over the last 40 yr, s‐CT has been investigated …

Purpose To investigate the dependence of microcalcification cluster detectability on
tomographic scan angle, angular increment, and number of projection views acquired at …
