  1. 26. Evaluation of astructured-light 3D-scanner for respiratory gating in PET/CT in a clinical setting

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Elin Wessel; [2018]
    Nyckelord :;

    Sammanfattning : In this study a structured light prototype device was evaluated for the possible use as a respiratory gating device in PET/CT. The device functions by measuring the movement in the vertical direction of the obtained 3D-surface of the chest and abdomen with the breathing. LÄS MER

  3. 27. Modelling and Simulations of a clinical PET-system using the GATE Monte Carlo software

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Philip Kalaitzidis; [2018]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: The increased importance of PET imaging in the health care system has lead to a constant need for improvement and optimisation of scanner systems and their protocols. By utilising the features of the GATE Monte Carlo program one can gain a better understanding of the limitations and possibilities of the system. LÄS MER

  4. 28. Development of Registration and Fusion Methods for the Jonasson Medical Imaging Center MiniPET-microCT

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Dimitrios Gkotsoulias; [2018]
    Nyckelord :miniPET; microCT; Medical imaging; Multimodality imaging; Registration; Fusion; Elastix; Mutual Information;

    Sammanfattning : Multimodal image registration is essential when combining functional and structural imaging modalities. Among the most common combinations, numerous methods have been developed for co-registration of CT and PET, typically validated on human size scanners. LÄS MER

  5. 29. Karakterisering av fettansättning hos katt samt dess betydelse för postmortal hullbedömning

    Master-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Tora Nyberg; [2017]
    Nyckelord :katt; felin; fetma; adipocyt; hullbedömning; BCS; fetmaassociserad sjukdom; datortomografi; magnetresonanstomografi; cat; feline; obesity; adipocyte; assessment of body condition; BCS; obesity associated disease; computed tomography; magnetic resonance imaging;

    Sammanfattning : SAMMANFATTNING Fetma är den vanligaste nutritionella orsaken till att hund och katt besöker smådjurskliniker i västvärlden och antal individer med fetma ökar stadigt. För att bedöma hull och fettmängd finns det flera metoder att använda på levande katt, medan postmortal hullbedömning vanligen baseras på en subjektiv uppskattning av kattens fettansättning utan tydligt definierbara kriterier.

  7. 30. Classifying patients' response to tumour treatment from PET/CT data: a machine learning approach

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Giulia Buizza; [2017]
    Nyckelord :treatment response; PET CT; Radiomics; feature extraction; support vector machines;

    Sammanfattning : Early assessment of tumour response has lately acquired big interest in the medical field, given the possibility to modify treatments during their delivery. Radiomics aims to quantitatively describe images in radiology by automatically extracting a large number of image features.
