1. 1. Evaluation of the DXA radiation environment at Sahlgrenska University Hospital

   University essay from

   Author : Saga Söderholm; [2022-05-18]
   Keywords : Medical physics; DXA; DEXA; Dual-energy X-ray absorptiometry; Bone mineral density;

   Abstract : Purpose: The aims of this work were to evaluate the radiation environment in the dual-energy X-ray absorptiometry (DXA) rooms at Sahlgrenska University Hospital, estimate personnel doses, determine legal requirements for DXA personnel, examine the operators’ view on radiation safety and develop material with dose information for patients and operators. Theory: DXA is a low dose X-ray modality mainly used in osteoporosis examinations, for which it is considered the reference technique. READ MORE

3. 2. Evaluation of portfolio optimization methods on decentralized assets and hybridized portfolios

   University essay from KTH/Matematik (Avd.)

   Keywords : Traditional assets; DeFi; Cryptocurrencies; CVAR; FLPM; MSV; Portfolio; Optimization; Risk measurements; Traditionella tillgångar; DeFi; Cryptocurrencies; CVAR; FLPM; MSV; Portfölj optimering; Riskmått;

   Abstract : The market for decentralised financial instruments, more commonly known as cryptocurrencies, has gained momentum over the past recent years and the application areas are many. Modern portfolio theory has for years demonstrated its applicability to traditional assets, such as equities and other instruments, but to some extent omitted the application of mathematical portfolio theory with respect for cryptocurrencies.

5. 4. Low dose CT for attenuation correction in PET. Validation of quantification for different patient sizes.

   University essay from Stockholms universitet/Fysikum

   Author : Anders Törnblom; [2019]
   Keywords : Attenuation correction PET PET CT dose CTDI ALARA Q.AC Phantom NEMA GE;

   Abstract : Introduction: Despite the relatively low dose (0.5 mSv – 1 mSv) generated by Attenuation Correction CT (ACCT) in PET examinations, the ALARA principle is still applicable. The currently used ACCT standard protocol at the Karolinska University Hospital in Solna uses 7. READ MORE

6. 5. Radiation protection measurements in clinical practice - Dosimetry with NaCl pellets

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Petter Wilke; [2019]
   Keywords : Physics and Astronomy;

   Abstract : Within the field of medical radiation protection, radiation safety and personal dosimetry, there is a constant pursuit for improving existing methods and evaluating new approaches for measuring and quantifying the radiation doses that hospital staff may be exposed to in their clinical work. There are numerous ways of determining what doses the staff are being exposed to and the most commonly used is based on thermoluminescent dosemeters (TLD) with e. READ MORE
