  1. 1. The impression technique for assessment of tissue oedema : instrumentation, evaluation and applications

    University dissertation from Linköping : LJ Foto & Montage

    Author : Olof Anton Lindahl; Linköpings universitet.; Linköpings universitet.; [1993]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICINE; MEDICIN; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Abstract : An instrument for clinical noninvasive assessment of tissue oedema based on an impression method was developed. The method measures and evaluates the decaying force, due to translocation of tissue fluid, during mechanical compression of any site of tissue. We applied the impression method on physical models, animal models, and patients. READ MORE

  2. 2. Textile-enabled Bioimpedance Instrumentation for Personalised Health Monitoring Applications

    University dissertation from KTH Royal Institute of Technology

    Abstract : 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.

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

    University dissertation from Department of Radiation Physics, Lund university

    Author : Anders Tingberg; Lunds universitet.; Lund University.; [2000]
    Keywords : 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;

    Abstract : Popular Abstract in Swedish Det är sedan länge känt att för samma bildkvalitet kan patientstråldosen variera kraftigt mellan två olika sjukhus för en och samma röntgenundersökning. Det finns ett stort utrymme för sänkning av patientstråldosen utan att undersökningens kvalitet påverkas. READ MORE

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

    University dissertation from Medical Radiation Physics, Lund University

    Author : Mark Ruschin; Lunds universitet.; Lund University.; [2007]

    Abstract : 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. READ MORE

    Abstract : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. READ MORE
