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

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Albin Lindvall; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 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.

  3. 2. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Dalia Farghaly; [2022]
    Nyckelord :nuclear physics; nuclear structure; proton drip-line; excited states; germanium; fusion-evaporation reaction; experimental nuclear physics; gamma sphere; gamma spectroscopy; HPGe detectors; data analysis; Physics and Astronomy;

    Sammanfattning : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. LÄS MER

  4. 3. Quantification of I-131 Activity from Gamma Camera Images of Thyroid Cancer Patients

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Frida Westerbergh; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : BACKGROUND: Radioiodine (131I) has been used in thyroid cancer treatments for many years, and has demonstrated good results with regards to disease management. Radioiodine therapy is however partially empirical, as not very much is known concerning radiation dosimetry. LÄS MER

  5. 4. Long term chaotic attitude behaviour on highly eccentric orbits : INTEGRAL Case Study

    Master-uppsats, KTH/Farkost och flyg

    Författare :Davide Menzio; [2016]
    Nyckelord :long-term propagation; attitude; stability; Poincaré map; momentum sphere.;

    Sammanfattning : The main issues discussed in this paper are related to the refinement of the on-ground casualty risk computation for the specific case of INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL). The current approach, unable to predict the spacecraft attitude motion, assumes random tumbling motion as initial condition to simulate the fragmentation process. LÄS MER
