1. Laboratory x-ray fluorescence tomography
Sammanfattning : 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. LÄS MER
2. Nanowire devices for X-ray detection
Sammanfattning : High spatial resolution X-ray microscopy has become a dedicated tool to study nanocrystals and nanostructure devices in recent years. In general, the spatial resolution of X-ray microscopy depends on the spot size of the X-ray beam and the pixel size of X-ray detectors. LÄS MER
3. Photon Counting X-ray Detector Systems
Sammanfattning : This licentiate thesis concerns the development and characterisation of X-ray imaging detector systems. “Colour” X-ray imaging opens up new perspectives within the fields of medical X-ray diagnosis and also in industrial X-ray quality control. LÄS MER
4. Characterisation and application of photon counting X-ray detector systems
Sammanfattning : This thesis concerns the development and characterisation of X-ray imaging systems based on single photon processing. “Colour” X-ray imaging opens up new perspectives within the fields of medical X-ray diagnosis and also in industrial X-ray quality control. LÄS MER
5. Small-Animal Imaging with Liquid-Metal-Jet X-Ray Sources
Sammanfattning : Small-animal x-ray imaging is an important tool for medical research. The penetration power of x-rays makes it possible to investigate the 3D structure of small animals and other thick biological samples by computed tomography (CT). LÄS MER
