1. Neutron Spectrometry Techniques for Fusion Plasmas : Instrumentation and Performance
Sammanfattning : Neutron are emitted from a deuterium plasma with energies around 2.5 MeV. The neutron spectrum is intimately related to the ion velocity distribution of the plasma. As a consequence, the analysis of neutron energy spectra can give information of the plasma rotation, the ion temperature, heating efficiency and fusion power. LÄS MER
2. Biokinetics and radiation dosimetry of 14C-labelled triolein, urea, glycocholic acid and xylose in man. Studies related to nuclear medicine “breath tests” using accelerator mass spectrometry
Sammanfattning : 14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. LÄS MER
3. Electronic instrumentation for nuclear physics research
Sammanfattning : .... LÄS MER
4. Evaluation of Automatic Quantification Programs for Myocardial Perfusion SPECT using Monte Carlo Simulations
Sammanfattning : Coronary artery disease (CAD) is a condition in which the blood supply to the myocardium is partially or completely blocked due to plaque build-up in the artery wall. Myocardial SPECT imaging is a commonly used technique to assess the blood flow to the myocardium and the function of the heart. LÄS MER
5. Internal Dosimetry Development and Evaluation of Methods and Models
Sammanfattning : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. LÄS MER
