1. 16. In-beam proton range monitoring during proton therapy : a Monte Carlo study on the feasibility of secondary gamma imaging

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Gustaf Lönn; [2016]
   Keywords : ;

   Abstract : Proton radiation therapy allows for delivering a high dose to a well-confinedregion of interest due to the characteristic proton dose deposition. Due to protonrange straggling, anatomic variations in patients and small patient setup errors,treatment plans needs to account for proton range uncertainties of up to 3.5% invivo. READ MORE

3. 17. Porous Asphalt Clogging Performance Under Swedish Conditions

   University essay from KTH/Byggvetenskap

   Author : Fuad Ahmed; [2015]
   Keywords : Air voids; clogging; noise; porous asphalt; X-ray; maintenance; Hålrum; igensättning; buller; bullerreducerande beläggning; tomografi; rengöring;

   Abstract : Porous asphalt has gradually gained a lot of popularity in the past ten years for its ability to reduce traffic noise, especially noise generated between tire and road surface. The acoustical absorption properties are mainly due to the pore structure and the texture of the mixture. READ MORE

4. 18. Development of narrow-bandwidth filters for the suppression of scattered light for optical and ultrasound analysis of tissue

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Philip Dalsbecker; [2015]
   Keywords : biophotonics; Maxwell-Bloch equations; tissue; ultrasound; Ultrasound-modulated optical tomography; UOT; Physics and Astronomy;

   Abstract : Ultrasound-modulated optical tomography (UOT) is a proposed diagnostic technique with potential as a means of discovering cancerous tumours. The technique combines ultrasound and laser radiation to probe tissue in a non-invasive, harmless way. READ MORE

5. 19. A porcine type 1 Diabetes Mellitus model, for non-invasive in vivo imaging of the glucagon-like peptide-1 receptor in the pancreas, using [68Ga]Ga-DO3A-VS-Cys40-conjugated synthetic exendin-4 in PET-CT

   University essay from SLU/Dept. of Clinical Sciences

   Author : Susanne Andréasson; [2014]
   Keywords : Exendin-4; GLP-1R; pig; beta cell imaging; beta cell mass; Exendin-4; gris; betacellsmassan; PET-CT;

   Abstract : Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls.

6. 20. A Comparison of Non-Destructive Techniques to Discover Defect Finger Joints in Furniture

   University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

   Author : Jonatan Björnberg; [2014]
   Keywords : Finger joint defects; Compare non-destructive techniques; Gluing of wood;

   Abstract : The aim of this study has been to investigate the possibilities to identify lack of glue in finger joints by checking different non-destructive techniques. Specifically, this study puts emphasis on finding a method suitable for an automated and fast industry production line of home furnishing products. READ MORE
