    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; radiologi; tomografi; tomography; medical instrumentation; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; Penh; emphysema; airway resistance; gas conditioning; plethysmography; lung mechanics; Boyle s law; Physiology; medicinsk instrumentering; Klinisk fysiologi; radiology; enhanced pause; pulmonary fibrosis; micro computed tomography; forced oscillation technique; COPD;

    Sammanfattning : In this thesis we explore and further develop several techniques used in the animal laboratory as well as in the clinical setting. In particular, we expand the understanding and usefulness of plethysmographic techniques in small rodents. LÄS MER

  3. 2. High resolution laboratory x-ray tomography for biomedical research : From design to application

    Författare :Till Dreier; Lund Medicinsk strålningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray; computed tomography; micro-CT; nano-CT; phase contrast; biomedical; super-resolution; material decomposition;

    Sammanfattning : Laboratory x-ray micro- and nano-tomography are emerging techniques in biomedical research. Through the use of phase-contrast, sufficient contrast can be achieved in soft tissue to support medical studies. LÄS MER

  4. 3. Multimodal and multiscale characterization of bone and bone interfaces in health and disease

    Författare :Chiara Micheletti; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone; osseointegration; characterization; mineralization; ultrastructure; diabetes; osteoporosis; MRONJ; surface functionalization; local drug delivery; titanium; bioactive glass; imaging; spectroscopy; microscale; nanoscale; micro-computed X-ray tomography; micro-Raman spectroscopy; scanning electron microscopy; transmission electron microscopy; PFIB-SEM tomography; electron tomography;

    Sammanfattning : Seeing is believing. Our understanding of phenomena often involves their direct observation. However, bone architecture is challenging to visualize given its multi-level hierarchical organization. LÄS MER

  5. 4. Computed Tomography of the Coronary Arteries : Developmental and Prognostic Investigations

    Författare :Mårten Sandstedt; Anders Persson; Joakim Alfredsson; Magnus Janzon; Jan Engvall; Mats Lidén; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Computed tomography (CT) is an increasingly used modality for investigations of patients with suspected coronary artery disease (CAD). Technical advances could improve diagnostic accuracy and lead to clinical workflow improvements. Also, more prognostic information can optimize clinical follow-up strategies and treatments. LÄS MER

  7. 5. Perfusion computed tomography of the liver

    Författare :Katharina Brehmer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Perfusion CT (P-CT) is a relatively new imaging technique that permits the visual and quantitative assessment of the micro- and macrocirculation of a target organ and focal lesions. P-CT has shown promising results in the evaluation of hyper-vascular tumors such as hepatocellular carcinoma (HCC). LÄS MER
