  1. 16. Quantitative Tissue Classification via Dual Energy Computed Tomography for Brachytherapy Treatment Planning : Accuracy of the Three Material Decomposition Method

    Master-uppsats, Institutionen för medicinsk teknik; Tekniska högskolan

    Författare :Merve Gürlüler; [2013]
    Nyckelord :brachytherapy; material decomposition; tissue classification; dual energy computed tomography;

    Sammanfattning : Dual Energy Computed Tomography (DECT) is an emerging technique that offers new possibilities to determine composition of tissues in clinical applications. Accurate knowledge of tissue composition is important for instance for brachytherapy (BT) treatment planning. LÄS MER

  3. 17. In-vitro study of antibiotic and strontium release from hydroxyapatite spheres and its PMMA composite

    Uppsats för yrkesexamina på avancerad nivå, Tillämpad materialvetenskap

    Författare :Martin Zarazua Mujo; [2011]
    Nyckelord :In vitro; antibiotic; strontium; hydroxyapatite; PMMA;

    Sammanfattning : The aim of this project was to study the in vitro release of cephalothin, vancomycin and strontium from hydroxyapatite particles and its PMMA composite. The hydroxyapatite spheres containing strontium were prepared in the laboratory. LÄS MER

  4. 18. Exon sequencing of the gene encoding UCMA/GRP in healthy and clinical subjects

    Magister-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Ebba Frånlund; [2011]
    Nyckelord :UCMA; GRP; PCR; DNA-sequencing; dideoxy-sequencing; pyrosequencing;

    Sammanfattning : Mineralization of soft tissues can cause significantly increased morbidity and mortality. The mechanism for this process is still unknown; however, patients with chronic kidney disease (CKD) are at high risk of developing vascular calcifications. LÄS MER

  5. 19. Quantitative Analysis of Bone Tissue Engineering Scaffolds and Skull Bones by means of Synchrotron and Conventional X-ray Computed Microtomography

    Master-uppsats, Teknisk biologi

    Författare :Emanuel Larsson; [2010]
    Nyckelord :X-ray Computed Microtomography; µ-CT; Pore3D; Hydroxyapatite; Bone Scaffolds; Bioglass ceramic scaffolds; Bioactivity; Bioresorption;

    Sammanfattning : The study of internal structure of materials has always been an essential issue in a variety of application fields, from the medical radiology to the materials science. X-ray computed microtomography (with both conventional and synchrotron radiation sources) has a great potential for these purposes because its three-dimensional and non destructive nature as well as the fact that it does not require any sample preparation and it allows to study samples under stress or after consecutive treatments.

  7. 20. Hierarchical Micro- and Nanostructured Superhydrophobic Surfaces to Reduce Fibrous Encapsulation of Pacemaker Leads : Nanotechnology in Practical Applications

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Louise Carlsson; [2008]
    Nyckelord :;

    Sammanfattning : The purpose of this master’s thesis was to, by the use of nanotechnology, improve material properties of the biomedical polymer Optim™, used as the insulation of pacemaker leads. Improved material properties are required to reduce the extent of fibrous encapsulation of the leads. LÄS MER
