  2. 1. Detection and 3-D positioning of small defects using digital radiography, 3-D point reconstruction, and tracking

    Author : Erik Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pore Defects; Radiographic Testing; Nondestructive Evaluation; Laser Welded Titanium; Multiple Hypothesis Tracking; X-ray Testing;

    Abstract : The weight and quality concerned aero industry is constantly trying to decrease the excess material in their components. With decreased weight the fuel consumption can be lowered and the negative environmental effects from aviation decreased. READ MORE

  4. 2. Idiopathic scoliosis : radiographic, neurophysiologic and psychologic aspects

    Author : Yngvi Ólafsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : idiopathic scoliosis; brace treatment; back surface analysis; self-image; somatosensory testing;

    Abstract : The aim of this thesis was to study brace treatment outcome, the brace effect on electromyographic muscle responses and self image, possible occurrence of somatosensory dysfunction and the descriptive power of surface topography contra radiography, in idiopathic scoliosis. There were 64 patients in a retrospective 4. READ MORE

  5. 3. Modelling of Radiographic Testing to Derive a Detection Positioning and Sizing Algorithm for Pore Defects

    Author : Erik Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : When laser welding light weight materials, e.g. aluminium and titanium based alloys, small sub-millimeter pore defects occasionally forms. Due to their small sizes, less than some 0. READ MORE

  6. 4. Radiographic follow-up analysis of Br?nemark? dental implants

    Author : Solweig Sundén Pikner; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cluster effect; Dental implants; Dependency; Diagnostic accuracy; Long-term follow-up; Marginal bone level; Observer variation; Osseointegration; Prediction;

    Abstract : Radiography plays an important role in clinical routine practice and in research projects evaluating dental implants, among them Br?nemark? System. Presence of a peri-implant radiolucency has been used in studies as a criterion for implant failure without knowledge of its diagnostic accuracy. READ MORE

  7. 5. Premolar autotransplantation in orthodontic treatment : a clinical and radiographic long-term study

    Author : Hans Ulrik Paulsen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Premolar aplasia and avulsed or malformed anterior teeth are common in young people. Using autotransplantation, it is possible to move problems in the dental arches to regions where they are more easy to solve orthodontically. READ MORE
