    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET CT; molecular imaging; image reconstruction; regularized reconstruction; quantification; oncology; neurology; cardiology; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Positron emission tomography (PET) combined with computed tomography (CT) is a widely used noninvasive molecular imaging modality with a broad range of clinical applications in oncology, neurology, and cardiology. Producing imperative image quality and accurate quantification are important driving forces behind the technological advances within PET image reconstruction and system development. LÄS MER

  5. 4. Methods of image acquisition and calibration for x-ray computed tomography

    Författare :Martin Sjölin; Mats Danielsson; J. Webster Stayman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Technology; Medicinsk teknologi;

    Sammanfattning : X-ray computed tomography (CT) is a common medical imaging device for acquiring high-resolution 3D images of the interior of the human body. The images are formed by mathematical reconstruction from hundreds of planar x-ray images that have been acquired during less then a second. LÄS MER

  7. 5. Quantifying image quality in diagnostic radiology using simulation of the imaging system and model observers

    Författare :Gustaf Ullman; Michael Sandborg; Gudrun Alm Carlsson; Nicolas Pallikarakis; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; radiation physics; image quality; optimisation; effective dose; chest radiography; Radiological physics; Radiofysik;

    Sammanfattning : Accurate measures of both clinical image quality and patient radiation risk are needed for successful optimisation of medical imaging with ionising radiation. Optimisation in diagnostic radiology means finding the image acquisition technique that maximises the perceived information content and minimises the radiation risk or keeps it at a reasonably low level.
