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

    Författare :Erik Lindgren; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Erik Lindgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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. LÄS MER

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

    Författare :Solweig Sundén Pikner; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Hans Ulrik Paulsen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
