  1. 1. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Måns Boll; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  3. 2. Development of methods for detection of radioactive aerosols of special importance for the ESS facility

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Martin Carlström; [2021]
    Keywords : alpha spectrometry; radioactive aerosols; spectrum simulation;

    Abstract : With the construction of the European Spallation Source (ESS) steadily approaching the operational phase, an environmental monitoring program will soon be implemented with the purpose of monitoring emissions. With regard to radiation safety, it is highly important to monitor alpha emitting radionuclides in aerosol form. READ MORE

  4. 3. Optimization of Acquisition Time for 177- Lu SPECT with Two Energy Windows

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Fanny Mörnsjö Centofanti; [2019]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Aim: The imaging process following the treatment of 177Lu-DOTATATE is in some medical clinics demanding on both patients and the clinic. Usually a number of images are acquired, with different time intervals to the time of injection. READ MORE

  5. 4. Validation of Catalyst HD™ positioning performance using a deformable phantom

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Beatrice Akinrimisi; [2019]
    Keywords : Medicine and Health Sciences;

    Abstract : Aim: The overall purpose for this master thesis was to evaluate the deformable algorithm of the optical surface scanning system Catalyst HDTM . The aim was to develop a method to evaluate the non-rigid registration algorithm using a deformable phantom and with it investigate the positioning accuracy of the depth calculation. READ MORE

  6. 5. Characterization of fading effects of a MOSFET semiconductor dosimeter to be used on an X-ray laser

    University essay from Stockholms universitet/Medicinsk strålningsfysik (tills m KI)

    Author : Wille Häger; [2017]
    Keywords : medical radiation physics semiconductor free-electron laser;

    Abstract : In the European XFEL, electrons bunches are accelerated up to 20 GeV and thenenter undulators where coherent X-rays are produced which can be used for imaging atva molecular level. Electrons may stray from the path and hit the permanent magnets inthe undulators. READ MORE
