Spectral imaging is an umbrella term for energy-resolved X-ray imaging in medicine. The
technique makes use of the energy dependence of X-ray attenuation to either increase the …

Abstract Knowledge of x-ray attenuation is essential for developing and evaluating x-ray
imaging technologies. For instance, techniques to better characterize cysts at …

In x-ray imaging, contrast information content varies with photon energy. It is, therefore,
possible to improve image quality by weighting photons according to energy. We have …

Beam quality optimization in mammography traditionally considers detection of a target
obscured by quantum noise on a homogenous background. It can be argued that this …

The purpose of this work is to derive a weighting scheme that maximizes the frequency-
dependent ideal observer signal-difference-to-noise ratio, commonly referred to as …

Purpose: Beam‐quality optimization in digital mammography traditionally considers
detection of a target obscured by quantum noise in a homogeneous background. This does …

We present a novel method for characterizing mammographic findings using spectral
imaging without the use of contrast agent. Within a statistical framework, suspicious findings …

We have designed a mammography system that for the first time combines photon-counting
spectral imaging with tomosynthesis. The present study is a comprehensive physical …

An easily implementable tissue cancellation method for dual energy mammography is
proposed to reduce anatomical noise and enhance lesion visibility. For dual energy …
