    Sammanfattning : The waiting list for lung transplantations world-wide is steadily growing. So, the use of lungs from non-heart-beating donors (NHBD) needs to be addressed. Hence, the aim of this thesis was to evaluate, in realistic animal models, the new donor organ concept: NHBD transplantation. LÄS MER

  3. 2. Lung mechanics in the aging lung and in acute lung injury. Studies based on sinusoidal flow modulation

    Författare :Ulrika Bitzén; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostics; Diagnostik; acute lung injury; lung mechanics; acute respiratory distress syndrome; intensivvård; Anestesiologi; intensive care; Anaesthesiology; Andningsorganen; Respiratory system; Fysiologi; Physiology; flow regulation; method; lung resistance; compliance; aging;

    Sammanfattning : Knowledge about lung mechanics is of interest in intensive care to adjust mechanical ventilation and in the lung laboratory for diagnostics and evaluation of patients with various kinds of respiratory diseases. In mechanical ventilation a single inspiratory elastic pressure-volume (Pel/V) curve is difficult to interpret due to continuing re-expansion of collapsed lung units over a large pressure interval.

    Sammanfattning : Lung diseases continue to present a large burden to public health, especially in industrialized countries. For abetter understanding of the underlying patho-mechanisms in lung related diseases as well as for testing theefficacy of novel therapies, preclinical studies in animal models are indispensable.

  7. 5. Development of methods for evaluation and optimization of chest tomosynthesis

    Författare :Angelica Svalkvist; Göteborgs universitet; []
    Nyckelord :Chest tomosynthesis; Evaluation; Optimization; Simulation; Image Quality; Dosimetry; Dose reduction; Nodule simulation; Validation;

    Sammanfattning : Tomosynthesis is a low-dose technique that has attracted increasing interest from the medical imaging community during the past decade. Tomosynthesis refers to the technique of acquiring a number of projection radiographs using extremely low exposure over a limited angular range, and using these radiographs to reconstruct slices of the imaged object.
