TOMOGRAPHIC IMAGE RECONSTRUCTION: IMPLEMENTATION, OPTIMIZATION AND COMPARISON IN DIGITAL BREAST TOMOSYNTHESIS
… most effective approach to detecting early stage breast cancer in the past decades of years. Tomosynthetic breast imaging is a potentially more valuable 3D technique for breast cancer detection. The limitations of current tomosynthesis systems include a longer scanning time than a conventional …

A multimodal breast cancer imaging system using coregistered dynamic diffuse optical tomography and digital breast tomosynthesis
… noninvasive functional imaging method for breast cancer diagnosis and neoadjuvant chemotherapy monitoring. In particular, the multimodal approach of combining DOT with x-ray digital breast tomosynthesis (DBT) is especially synergistic as DBT prior information can be used to enhance the DOT …

Image reconstruction and imaging configuration optimization with a novel nanotechnology enabled breast tomosynthesis multi-beam X-ray system
<p>Digital breast tomosynthesis is a new technology that provides three-dimensional information of the breast and makes it possible to distinguish the cancer from overlying breast tissues. We are dedicated to optimizing image reconstruction and imaging configuration for a new multi-beam parallel …

Missed Breast Cancer Risk Factors and Clinicopathologic Features: A Six-Year Analysis of Data from a Single Institution
BACKGROUND: Breast cancer is the second most commonly diagnosed cancer in women, but mortality has been consistently decreasing due to the introduction of screening mammography and continual innovations in treatment [1,13,15]. However, cancers missed on screening and diagnostic imaging studies …

Perceptually Relevant Measurements in Tomosynthesis Imaging
… relevant to mammography like radiation dose, breast density and thickness, pixel size, arc span and number of projections in the case of digital breast tomosynthesis (aka 3D mammography) can alter the cancer screening diagnosis. Therefore, it is necessary to find which configuration is best so …

Investigation of optical and imaging characteristics of fluorescent screens for use in digital imaging detectors suitable for telemedicine
Indirect detection digital imaging systems used in medical imaging, compromises powder phosphor scintillators as X-ray to light converters. Powder phosphors should combine image quality and light output parameters in order to produce high quality diagnostic images, with the parallel dose reduction …

Image Processing Methods For Dual-Energy Contrast-Enhanced X-Ray Breast Imaging
Imaging of the breast is essential for the early detection and diagnosis of breast cancer. Digital mammography (DM) and digital breast tomosynthesis (DBT) are the current standards of care for breast cancer screening. However, these imaging modalities are insufficient for screening women who have a …

Development of High-performance Flexible Poly-Si Thin Film Transistors and GaAs PIN Photodiode for Advanced X-ray Imaging
Digital X-ray imaging techniques are widely adopted for medical diagnosis and industrial inspections. However, the existing flat panel detectors fail to meet the challenges posed by large-area and curved surface imaging. They are also inadequate for low radiation dose and high spatial resolution …
