  1. 1. Only a Shadow : Industrial computed tomography investigation, and method development, concerning complex material systems

    Författare :Anton Jansson; Lars Pejryd; Jens Ekengren; Peter Hammersberg; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computed tomography; Dual-energy; Material investigation; Additive manufacturing; Measurement consistency; Maskinteknik; Mechanical Engineering;

    Sammanfattning : The complexity of components fabricated in today's industry is ever increasing. This increase is partly due to market pressure but it is also a result from progress in fabrication technologies that opens up new possibilities. LÄS MER

  3. 2. Dual-energy imaging in stroke : feasibility of dual-layer detector cone-beam computed tomography

    Författare :Fredrik Ståhl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Dual-energy computed tomography (DECT) is increasingly available and used in the standard diagnostic setting of ischemic stroke patients. For stroke patients with suspected large vessel occlusion, cone-beam computed tomography (CBCT) in the interventional suite could be an alternative to CT to shorten door to thrombectomy time.

  4. 3. Body composition and quality of life in patients with IBD, ileostomy and short bowel syndrome

    Författare :Eva Carlsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammatory bowel disease; Crohn´s disease; ulcerative colitis; short bowel syndrome; quality of life; health related quality of life; coping; concern; body composition; bioelectric impedance spectroscopy; Dual-energy absorptiometry; total body water;

    Sammanfattning : Patients with IBD are at risk for intestinal disability (e.g. having a stoma, malnutrition). The general aim of the thesis was to investigate physiological, psychological and social consequences of having IBD and an ileostomy or short bowel syndrome (SBS). LÄS MER

  7. 5. Computer-aided detection and novel mammography imaging techniques

    Författare :Hans Bornefalk; Mats Danielsson; Robert Nishikawa; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computer-aided detection; FROC; mammography; optimal operating points; single-shot dual-energy imaging; Radiological physics; Radiofysik;

    Sammanfattning : This thesis presents techniques constructed to aid the radiologists in detecting breast cancer, the second largest cause of cancer deaths for western women. In the first part of the thesis, a computer-aided detection (CAD) system constructed for the detection of stellate lesions is presented. LÄS MER
