  2. 21. Prevention and treatment of experimental peri-implantitis

    Author : Ahmed Almohandes; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peri-implantitis;

    Abstract : Peri-implantitis is a plaque-associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri-implant mucosa and progressive loss of supporting bone. READ MORE

  4. 22. Tomographic methods in endovascular aortoiliac treatment

    Author : Per Törnqvist; Vaskulära sjukdomar - kliniska studier; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Endovascular treatment had developed rapidly and the procedures have increased in complexity. The demand of imaging excellence is imperative to perform these interventions. However both pre and postoperative investigations are performed by the use of advanced three-dimensional imaging, while the treatment itself relies on two-dimensional imaging. READ MORE

  5. 23. Interlaced proton grid therapy: development of an innovative radiation treatment technique

    Author : Thomas Henry; Irena Gudowska; Tony Lomax; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; grid therapy; spatially fractionated therapy; interlacing; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Spatially fractionated radiotherapy, also known as grid therapy (GRID), has been used for more than a century to try to treat several kinds of lesions. Yet, the grid technique remains a relatively unknown and uncommon treatment modality nowadays. READ MORE

  6. 24. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications

    Author : Kristin Persson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extinction theorem; inverse source problem; integral representation; radome diagnosis; near-field transformation;

    Abstract : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. READ MORE

  7. 25. New technologies for the further advancement of ERCP

    Author : Marcus Reuterwall Hansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: The capabilities of conventional endoscopic retrograde cholangiopancreatography (ERCP) are hampered by several limitations. Newly developed adjunct technologies such as single operator peroral cholangiopancreatoscopy (SOPCP) and new imaging techniques could overcome some of these limitations, but their role in common clinical practice have not yet been established.
