    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Bioimpedance Spectroscopy; Thoracic Bioimpedance Spectroscopy; Sub-Nyquist Sampling; Undersampling; Aliasing in Electrical Bioimpedance; Bioimpedance Estimation Error.; Medicinsk teknologi; Medical Technology; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Electrical bioimpedance spectroscopy (EBIS) has been used to assess the status or composition of various types of tissue, and examples of EBIS include body composition analysis (BCA) and tissue characterisation for skin cancer detection. EBIS is a non-invasive method that has the potential to provide a large amount of information for diagnosis or monitoring purposes, such as the monitoring of pulmonary oedema, i. LÄS MER

  2. 2. Improvements in Bioimpedance SpectroscopyData Analysis Artefact Correction, ColeParameters, and Body Fluid Estimation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ruben Buendia; Rubén Buendía López; KTH.; Högskolan i Borås.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioimpedance; Cole; Body Fluid;

    Sammanfattning : The estimation of body fluids is a useful and common practice in the status assessment of diseasemechanisms and treatments. Electrical bioimpedance spectroscopy (EBIS) methods are non-invasive,inexpensive, and efficient alternatives for the estimation of body fluids. However, these methods areindirect, and their robustness and validity are unclear. LÄS MER

    Sammanfattning : Neurologically related injuries cause a similar number of deaths ascancer, and brain damage is the second commonest cause of death in theworld and probably the leading cause of permanent disability. Thedevastating effects of most cases of brain damage could be avoided if itwere detected and medical treatment initiated in time. LÄS MER

  4. 4. Model Based Enhancement of Bioimpedance Spectroscopy Analysis Towards Textile Enabled Applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Rubén Buendía López; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physiological measurements; Bioimpedance; modelling; textiles;

    Sammanfattning : Several signal processing approaches have been developed to overcome the effect of stray capacitances in Electrical Bioimpedance Spectroscopy (EBIS) measurements. EBIS measurements obtained with textile-enabled instrumentation are more vulnerable to stray capacitances. LÄS MER

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