  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. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

    Master-uppsats,

    Författare :Victor Asp; [2022-01-13]
    Nyckelord :Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

    Sammanfattning : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. LÄS MER

  4. 3. KVANTIFIERING AV ADMINISTRERAD AKTIVITET VID LUNGSCINTIGRAFI OCH VALIDERING AV METODEN

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Heba Raed; [2022]
    Nyckelord :Activity; gamma detector; lung scintigraphy; perfusion; quota; radiation dose; ventilation.; Aktivitet; gammadetektor; kvot; lungscintigrafi; perfusion; stråldos; ventilation.;

    Sammanfattning : Lungscintigrafi är en av de mest vanligt förekommande nuklearmedicinska undersökningarna. Akut lungemboli är en huvudindikation för lungscintigrafi. Undersökningen består av två delar, först undersöks ventilationsdelen och sedan perfusions-fördelningen i lungan. Vid ventilationen inhalerar patienten 99mTc-Technegas. LÄS MER

  5. 4. Feasibility of Dynamic SPECT-Renography with Automated Evaluation Using a Deep Neural Network

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Viktor Rogowski; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Renography is a standard diagnostic examination that evaluates renal function, renal pelvic dilatation and urinary obstruction. Renography is performed by injecting a radiopharmaceutical (predominately 99mTc-MAG3) and using gamma camera to image the biodistribution in a dynamic sequence. LÄS MER

  7. 5. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Miguel Llamas Lanza; [2021]
    Nyckelord :Gamma-ray Bursts; GRBs; compact objects; high energy; ECLAIRs; SVOM; high redshift; T90; detection biases;

    Sammanfattning : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. LÄS MER
