  1. 1. A Monte Carlo simulation study of collimators for a high-spatial-resolution Gamma Emission Tomography instrument

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Anastasios Anastasiadis; [2019]
    Keywords : ;

    Abstract : The present master thesis concerns a study of collimator designs for a high-spatial-resolution Gamma Emission Tomography (GET) instrument for used fuels utilizing Monte Carlo simulation codes. Designing a collimator for this purpose is a multilateral process that requires many interconnected and conflicting objectives to be taken into consideration. READ MORE

  2. 2. Psychedelic agents : Changes induced in subjective experience and brain activity

    Author : Louise Andersson; [2019]
    Keywords : psychedelic; hallucinogen; subjective experience; phenomenology; brain imaging; electroencephalogram; magnetic resonance imaging; positron emission tomography;

    Abstract : This thesis combines phenomenological and neuroscientific research to elucidate the effects of psychedelic agents on the human brain, mind and psychological well-being. Psychoactive plants have been used for thousands of years for ceremonial and ritual purposes. READ MORE

  3. 3. Nucleophilic 18F-Labelling of Galectin-3 Inhibitors for PET Analysis

    University essay from Lunds universitet/Kemiska institutionen; Lunds universitet/Centrum för analys och syntes

    Author : Edvard Torkelsson; [2018]
    Keywords : galectins; inhibitors; protein; organic chemistry; organisk kemi; Chemistry;

    Abstract : Galectins are a family of proteins naturally occurring in humans involved in a broad variety of bodily functions, including regulation of immune response and inflammation. The most studied protein of the family, galectin-3, has repeatedly been proven to be involved in tumour progression, affecting both tumour survival and metastasis. READ MORE

  4. 4. Development and Evaluation of a Tomographic Technique for Volumetric Imaging of Flames

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

    Author : David Sanned; [2018]
    Keywords : 3D-Tomography; Additive Reconstruction Technique; Space Carving; Machine Vision Cameras; Imaging of Flame Models; Technology and Engineering; Physics and Astronomy;

    Abstract : With modern day interest to continue the reduction of harmful emissions and improve the efficiency of combustion devices, the need to further improve upon accuracy and ability to describe combustive processes is of high value. Nowadays, multiple capable point (0D) and two-dimensional measurement (2D) techniques exist for flame investigation, however as combustion nearly always is a three-dimensional (3D) process some limitations do exist within many of these techniques.

  5. 5. A comparison of classification accuracy between MRI and PET datasets in computer aided diagnosis of Alzheimer's disease

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Kjellberg; Henrik Kälvegren; [2018]
    Keywords : ;

    Abstract : The number of people suffering from Alzheimer’s disease (AD) is expected to increase rapidly in the coming years. Diagnosing the disease early is key to giving those affected a chance to maintain a higher quality of life. One of the most common ways to detect AD is to visually inspect scans of the patients’ brains. READ MORE
