31. SIMIND Based Pinhole Imaging Development and Validation
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : The Monte Carlo method has become increasingly used to simulate imaging systems like the scintillation camera and SPECT systems. In order to investigate intrinsic properties of SPECT systems the Monte Carlo based application SIMIND (Simulating Medical Imaging Nuclear Detectors) has been developed. READ MORE

32. Verification of dose limitation of the general public and determination of lead equivalence of x-ray rooms at Karolinska University Hospital Huddinge
University essay from Medicinsk strålningsfysik (tills m KI)Abstract : A variety of radiation sources exist at the Department of Radiology and the Department of Nuclear Medicine at Karolinska University Hospital Huddinge. Radiation sources can also be found in areas outside of these departments due to the wide use of mobile xray machines and fluoroscopic c-arm equipment and also due to the movement of patients that have received diagnostic or therapeutic doses of radionuclides.

33. Experimental Radionuclide Therapy Quantitative Pinhole planar and SPECT imaging, aiming for dosimetry based on biokinetic modeling and small animal S-values
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : New radionuclide therapies in humans should be preceded by experimental animal therapies, in order to evaluate the efficacy of the new therapy regime. These experimental studies have to be performed with a reliable and accurate quantification system, with properties that have been evaluated and where possible flaws have been corrected for.

34. Analysis of the Benefit of Quantification in Myocardial Perfusion Imaging A human observer ROC evaluation using Monte Carlo Simulated Data
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : "The purpose of this study was to evaluate the benefit of commercial quantification software in perfusion SPECT imaging by simulating a group of patients and their corresponding SPECT acquisitions using a computer phantom and a Monte Carlo program. Based on decisions from experienced physicians and their visual interpretation of the simulated patient images, without and with addition of the information from the quantitative perfusion software, the benefit of such a quantification program was evaluated from a ROC analysis.

35. Polyhalogenated organic pollutants in amphibians
University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public HealthAbstract : Polyhalogenated organic pollutants are xenobiotics, which are believed to cause considerable environmental pollution and human health problems as a result of their persistence, toxicity, and transformation into hazardous metabolites. These chemicals are persistent and are biomagnificated in the ecosystem. READ MORE
