With flat-panel detector mammography, radiography, and fluoroscopy systems, digital tomosynthesis (DT) has been recently introduced as an advanced clinical application that removes overlying structures, enhances local tissue separation, and provides depth information about structures of interest by providing high-quality tomographic images. DT images are(More)
PURPOSE We have demonstrated the ability to identify coronary calcium, a reliable biomarker of coronary artery disease, using nongated, 2-shot, dual energy (DE) chest x-ray imaging. Here we will use digital simulations, backed up by measurements, to characterize DE calcium signals and the role of potential confounds such as beam hardening, x-ray scatter,(More)
Coronary artery calcification (CAC) is the lead biomarker for atherosclerotic heart disease. We are developing a new technique to image CAC using ubiquitously ordered, low cost, low radiation dual energy (DE) chest radiography (using the two-shot GE Revolution XRd system). In this paper, we proposed a novel image processing method (CorCalDx) based on(More)
This study was undertaken to evaluate the use of digital tomosynthesis (tomogram) for diagnosis of suspected fracture neck of femur (NOF). We hypothesised that the use of cross-sectional imaging (MRI/CT) could be reduced by using tomogram to separate the patients with suspected NOF fractures that require MRI/CT scan from those who do not. Forty-one patients(More)
