  2. 1. Phase-Contrast X-Ray Carbon Dioxide Angiography

    Author : Ulf Lundström; Hans Hertz; Anna Burvall; Ulrich Vogt; Franz Pfeiffer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Phase-contrast x-ray imaging is an emerging technology, which allows for imaging of smaller features than conventional absorption-based x-ray imaging, with lower radiation dose. Instead of the attenuation that is normally used in x-ray imaging, it utilizes the phase shift introduced by an object to the transmitted x-rays. READ MORE

  4. 2. Quantification and Maximization of Performance Measures for Photon Counting Spectral Computed Tomography

    Author : Moa Yveborg; Hans Bornefalk; Franz Pfeiffer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectral computed tomography; silicon detector; detectability index; photon counting; Hotelling SDNR; material basis decomposition;

    Abstract : During my time as a PhD student at the Physics of Medical Imaging group at KTH, I have taken part in the work of developing a photon counting spectrally resolved silicon detector for clinical computed tomography. This work has largely motivated the direction of my research, and is the main reason for my focus on certain issues. READ MORE
