  1. 1. Monte Carlo Simulations of a Clinical PET system using the GATE Software

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Henrik Bertilsson; [2009]
    Nyckelord :Nukleärmedicin; Medicine and Health Sciences;

    Sammanfattning : Introduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications. The purpose of this work was (1) to understand the basics of the Monte Carlo simulation software Geant4 Application for Tomographic Emission (GATE); (2) to create a model of Philips Gemini TF PET/CT system; (3) to run a number of simulations to compare the performance of the model to published data for this system; and (4) to further investigate how scattered radiation affects the image quality.

  2. 2. OCCUPATIONAL EXPOSURE of 14C a systematic investigation of 14C contamination of workers at the nuclear power industry, the pharmaceutical industry and other laboratories using 14C

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Carl-Magnus Nilsson; [2008]
    Nyckelord :Nukleärmedicin; Medicine and Health Sciences;

    Sammanfattning : With the help from accelerator mass spectrometry (AMS), hair from workers within the nuclear power industry, pharmaceutical and biotechnology industry has been investigated to see if contamination from 14C. 14C-using companies and nuclear power plants were contacted, volunteers were recruited, who sent in hair samples together with a questionnaire.

  3. 3. Production of 89Zr for labelling of antibodies to be evaluated preclinically with micro-PET for radioimmunodiagnostics of prostate cancer

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Christoffer Svensson; [2008]
    Nyckelord :Nukleärmedicin; Medicine and Health Sciences;

    Sammanfattning : Introduction: Prostate cancer is the most common cancer type among men in Sweden. The malignant growth is normally a slow process and most patients are diagnosed at an age of 70 or more. However, some are subjected to a more aggressive form that requires an early diagnose to enhance the chances to overcome the disease. LÄS MER

  4. 4. Intensity Modulated Proton Therapy (IMPT) - A comparative treatment planning study

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Malin Ericsson; [2007]
    Nyckelord :Nukleärmedicin; Medicine and Health Sciences;

    Sammanfattning : Purpose: To study Intensity Modulated Proton Therapy (IMPT) with a new treatment planning optimization software. The aim was also to make a comparative study between existing conventional photon plans, Intensity Modulated X-ray Therapy (IMXT) plans and IMPT plans for three different cancer diagnoses. LÄS MER

  5. 5. Reduction of the absorbed dose to the urinary bladder from radiopharmaceuticals -An investigation of influencing parameters

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Morgan Schönbeck; [2007]
    Nyckelord :Nukleärmedicin; Medicine and Health Sciences;

    Sammanfattning : Introduction: The main route of excretion of activity for most administered radiopharmaceuticals is via the urinary bladder and it is important to estimate the absorbed dose to the mucosal surface of the bladder wall, especially when radiopharmaceuticals are given for therapeutic purposes. The purpose of this thesis was to investigate how the absorbed dose varies with changes in the parameters, which control the volume in the bladder. LÄS MER
