Digital Mammography / IWDM
Digital mammography has limitations in sensitivity, in particular for patients with a dense breast. Phase contrast techniques phase contrast mammography, PCM might increase the tissue contrast for breast imaging. Propagation based PCM with a dedicate

The aim of the SYRMA-CT collaboration is to set-up the first clinical trial of phase-contrast breast CT with synchrotron radiation (SR). In order to combine high image quality and low delivered dose a number of innovative elements are merged: a CdTe

The major objective is to adopt, apply and test developed in-house algorithms for volumetric breast reconstructions from projection images, obtained in in-line phase-contrast mode. Four angular sets, each consisting of 17 projection images obtained f

Purpose: In cone-beam computed tomography (CBCT), and in particular in cone-beam breast computed tomography (CBBCT), an important issue is the reduction of the image artifacts produced by photon scatter and the reduction of patient dose. In this work

We present the first measurements with the energy sensitive Timepix pixel detector for electron imaging. The hybrid pixel detector consists of a silicon detector, 300 μm thick, bump-bonded to the Timepix readout chip developed by the Medipix2 collab

We measured the spatial resolution of the prototype scanner developed for laboratory investigations on Cone-Beam Breast Computed Tomography (CBBCT). The scanner has potential for high spatial resolution, since it employs a minifocus X-ray tube (0.04

Purpose The goal of this study is to evaluate a new method based on a coded aperture mask combined with a digital x-ray imaging detector for measurements of the focal spot sizes of diagnostic x-ray tubes. Common techniques for focal spot size measure
