  1. 1. Laboratory x-ray fluorescence tomography

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jakob C. Larsson; KTH.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray; fluorescence; x-ray fluorescence; nanoparticle; xrf; xfct; tomography; Physics; Fysik;

    Abstract : X-ray fluorescence (XRF) tomography is an emerging bio-imaging modality with potential for high-resolution molecular imaging in 3D. In this technique the fluorescence signal from targeted nanoparticles (NPs) is measured, providing information about the spatial distribution and concentration of the NPs inside the object.
