11. Gamma camera emission tomography : development and properties of a multi-sectional emission computed tomography system
Sammanfattning : .... LÄS MER
12. Analyses and Application of Ambient Seismic Noise in Sweden : Source, Interferometry, Tomography
Sammanfattning : Ambient seismic noise from generation to its application for determination of sub-surface velocity structures is analyzed using continuous data recordings from the Swedish National Seismic Network (SNSN). The fundamental aim of the thesis is to investigate the applicability of precise velocity measurements from ambient noise data. LÄS MER
13. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study
Sammanfattning : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirement for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain components. LÄS MER
14. 3D X-ray microscopy: image formation, tomography and instrumentation
Sammanfattning : Tomography in soft X-ray microscopy is an emerging technique for obtaining quantitative 3D structural information about cells. One of its strengths, compared with other techniques, is that it can image intact cells in their near-native state at a few 10 nm’s resolution, without staining. LÄS MER
15. Experimental verification of tomographic measurement methods in ultrasound
Sammanfattning : This thesis describes two different measurement methods applied to ultrasound. The first method, Ultrasound doppler vector tomography, uses ultrasound to measure blood flow and the second method, Light diffraction tomography, measures the pressure field in an ultrasound beam with laser light.
