  1. 1. Calculating Center of Mass Using List Mode Data from PET Biograph128 mCT-1104

    University essay from KTH/Medicinteknik och hälsosystem; KTH/Medicinteknik och hälsosystem

    Author : Lukas Rane; Henrik Runeskog; [2019]
    Keywords : PET; List Mode; Image Reconstruction; e7-tools; Siemens; Center of Mass; PET; List Mode; Bildrekonstruktion; e7-tools; Siemens; Masscentrum;

    Abstract : A common problem within positron emission tomography examinations of the brain is the motion of the patient. If the patients ́ head moves during an examination all the data acquired after the movement will not be suited for clinical use. This means that a lot of data recovered from PET is not used at all.

  2. 2. 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

    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

  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.

    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
