  1. 16. Pain in Osteoarthritic Joints: Biological Signaling and 3D Models based on Imaging

    Författare :Birgitta Gatenholm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; pain in knee joints; cartilage lesions; micro-computed tomography; 3D CAD models; neuropeptides;

    Sammanfattning : Osteoarthritis (OA) is the most common joint disease, causing disability in middle-aged and elderly patients worldwide and imposing a huge socioeconomic burden. OA of the knee joint is a major cause of joint pain and, along with back pain, it accounts for the two most-reported causes of chronic pain. LÄS MER

  3. 17. Automated Patient-Specific Multi-tissue Segmentation of MR Images of the Head

    Författare :Mahmood Qaiser; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D image segmentation; mean shift; Bayesian; Magnetic resonance; brain or head tissues; source localization.;

    Sammanfattning : The automated segmentation of magnetic resonance (MR) images of the human head is an active area of research in the field of neuroimaging. The resulting segmentation yields a patient-specific labeling of individual tissues and makes possible quantitative characterization of these tissues (e.g. LÄS MER

  4. 18. 3D Rotational Angiography of Transplanted Renal Arteries : A Clinical and Experimental Study

    Författare :Gaute Hagen; Anders Magnusson; Jonas Wadström; Jarl Jakobsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Kidney; transplantation; renal angiography; renal arteries; stenosis or obstruction; imaging; three-dimensional; artifacts; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Sammanfattning : Three-dimensional rotational angiography (3D-RA) is an established method within the field of interventional neuroradiology. The method has also a great potential in other areas with a complicated arterial anatomy. LÄS MER

  5. 19. 2D and 3D Halftoning for Appearance Reproduction

    Författare :Fereshteh Abedini; Sasan Gooran; Daniel Nyström; Jan Morovic; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The appearance of an object is determined by its chromatic and geometric qualities in its surrounding environment using four optical parameters: color, gloss, translucency, and surface texture. Reconstructing the appearance of objects is of great importance in many applications, including creative industries, packaging, fine-art reproduction, medical simulation, and prosthesis-making.

    Sammanfattning : Cancer is one of the leading causes of death worldwide. In 2020, there were around 10 million cancer deaths and nearly 20 million new cancer cases in the world. Radiation therapy is essential in cancer treatments because half of the cancer patients receive radiation therapy at some point. LÄS MER
