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


    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

  2. 2. 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

  3. 3. 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

  4. 4. Development of an MRI-compatible Multi-compartment Phantom for Dynamic Studies

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem; KTH/Medicinteknik och hälsosystem

    Författare :Jonas Ström Seez; Frederick Holmer Fann; [2020]
    Nyckelord :Dynamic studies; Dynamic phantom; Multi-compartment analysis; MRI compatible; PET; SPECT; Gamma camera; Nuclear medicine; Dynamiska studier; Dynamisk fantom; Multi-kammar analys; MRI kompatibel; PET; SPECT; Gammakamera; Nuklearmedicin;

    Sammanfattning : Medical imaging based on radioactive tracers exposes the patient to radiation. For this reason, a phantom is preferably used for non-clinical studies such as routine quality assurance and research. The aim of this project was to design, build and test a multi-compartment phantom to be used in dynamic SPECT/CT, PET/CT and PET/MRI studies. LÄS MER

  5. 5. Characterization of γ-rays at MAST

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Erik Blom; [2019]
    Nyckelord :fusion; MAST; MAST upgrade; neutron collimated flux monitor; neutron camera; gamma-ray;

    Sammanfattning : The γ-ray characterizing possibility of the neutron collimated flux monitor (in short, Neutron Camera) at the Mega Ampere Spherical Tokamak (MAST) is explored. Typically used to monitor neutron emission, the Neutron Camera has excellent neutron/γ-ray discrimination properties and thus presents the opportunity to measure spatially and temporally resolved γ-ray emission - a possibility of an additional fusion diagnostics method with already existing equipment.
