    Author : Ivan Rashid; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. READ MORE

  3. 2. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Albin Lindvall; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

  6. 5. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ann-Kathrin Wild; [2022]
    Keywords : trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

    Abstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.
