1. 11. The role of new ultrasound modalities to refine the diagnostic workup on women with cervical carcinoma

   Författare :Kolbrún Pálsdóttir; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Cervical cancer is the fourth most common female cancer in the world and has traditionally been clinically staged not including imaging. Despite that, clinicians depend on diagnostic imaging in the management of patients to triage them to treatment. LÄS MER

3. 12. The role of X-ray imaging and musculoskeletal ultrasound in the diagnosis and management of rheumatoid arthritis

   Författare :Hamed Rezaei; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease characterized by symmetric joint inflammation that often involves the small joints of the hands and feet, with progressive destruction, deformity, and disability of the joints. Small joints of the hands and feet are frequently the first to be involved in RA, which is why methods for assessment of these joints are of particular importance at the onset of RA and early stage of the disease.

4. 13. Spindle vibration and sound field measurement using optical vibrometry

   Författare :Kourosh Tatar; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Mechanical systems often produce a considerable amount of vibration and noise. To be able to obtain a complete picture of the dynamic behaviour of these systems, vibration and sound measurements are of significant importance. Optical metrology is well-suited for non-intrusive measurements on complex objects. LÄS MER

5. 14. Novel Diagnostic Tools for Skin and Periorbital Cancer - Exploring Photoacoustic Imaging and Diffuse Reflectance Spectroscopy

   Författare :Ulf Dahlstrand; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The eyelids are susceptible to a number of skin cancers which are challenging to excise radically without sacrificing excessive healthy tissue. The way in which a tumor is delineated preoperatively has not changed significantly over the past century. LÄS MER

7. 15. Manifolds in Image Science and Visualization

   Författare :Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Roland Wilson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; manifold learning; image analysis; signal processing; diffusion tensor mri; Medical engineering; Medicinsk teknik;

   Sammanfattning : A Riemannian manifold is a mathematical concept that generalizes curved surfaces to higher dimensions, giving a precise meaning to concepts like angle, length, area, volume and curvature. A glimpse of the consequences of a non-flat geometry is given on the sphere, where the shortest path between two points – a geodesic – is along a great circle. LÄS MER
