  1. 6. Electrical Bioimpedance Cerebral Monitoring: Fundamental Steps towards Clinical Application

    Författare :Fernando Seoane Martinez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedical Instrumentation; Ischemia; Hypoxia; Non-invasive Monitoring; Electrical Bioimpedance Spectroscopy; Stroke; Impedance Measurements; Brain Monitoring;

    Sammanfattning : Neurologically related injuries cause a similar number of deaths as cancer, and brain damage is the second commonest cause of death in the world and probably the leading cause of permanent disability. The devastating effects of most cases of brain damage could be avoided if it were detected and medical treatment initiated in time. LÄS MER

  3. 7. Quantifying the quality of medical x-ray images. An evaluation based on normal anatomy for lumbar spine and chest radiography

    Författare :Anders Tingberg; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; normal anatomy; free response forced error FFE ; receiver operating characteristics ROC ; visual grading analysis VGA ; European image criteria; quantifying clinical image quality; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Optimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. LÄS MER

  4. 8. Modular textile-enabled bioimpedance system for personalized health monitoring applications

    Författare :Javier Ferreira; Fernando Seoane; Kaj Lindecrantz; Orjan Grottem Martinsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; personal healthcare system; electrical bioimpedance; wearable sensors; pervasive monitoring; portable monitoring; body composition; chronic kidney disease; wireless sensor; ubiquitous; instrumentation; Technology and Health; Teknik och hälsa;

    Sammanfattning : A growing number of factors, including costs, technological advancements, ageing populations, and medical errors, are leading industrialized countries to invest in research on alternative solutions to improve their health-care systems and increase patients’ quality of life. Personal health systems (PHS) examplify the use of information and communication technologies that enable a paradigm shift from the traditional hospital-centered healthcare delivery model toward a preventive and person-centered approach.

  5. 9. Biomarkers of Inflammation and Intestinal Mucosa Pathology in Celiac Disease

    Författare :Hanna Gustafsson Bragde; Jan Söderman; Ulf Jansson; Ewa Grodzinsky; Mats Fredrikson; Ross McManus; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Celiac disease (CD) is a chronic small intestinal immune-mediated enteropathy triggered by gluten. The only currently available treatment is complying with a lifelong gluten-free diet, which should not be commenced before a CD diagnosis has been established by diagnostic test results (including histopathologic assessment of small intestinal biopsies and CD-specific antibody levels).

  7. 10. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography

    Författare :Mark Ruschin; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D breast imaging; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; hybrid images; dose reduction; spatial resolution; pixel size; Breast cancer; digital mammography; radiologi; tomografi; medicinsk instrumentering; breast tomosynthesis;

    Sammanfattning : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. LÄS MER
