  1. 1. Development of a thin, soft, single segment conductance catheter for monitoring left ventricular pressure and volume

    Författare :Camilla Carlsson; KTH; []
    Nyckelord :Left ventricular function; Left ventricular volume; Conductance catheter; Segment volume;

    Sammanfattning : Knowledge of the leftventricular (LV) pressure-volume relation, along withparameters derived from this relation, have led to newpossibilities for the characterisation of cardiac pumpfunction, in both experimental studies and clinicalsettings.The pressure-volume diagram is apowerful tool for visualising LV performance, but in order tobe clinically useful it is necessary to make plots continuouslyand on-line.

  4. 3. Cardioplegia and cardiac function : evaluated by left ventricular pressure-volume relations

    Författare :Anders B Ericsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cardioplegia; simultaneous cardioplegia; intermittent warn cardioplegia; cardiac function; pressure-volume loops; conductance catheter; heart rate;

    Sammanfattning : Purpose: This thesis is focused on studies of blood cardioplegia in order to evaluate regimens of myocardial protection during cardiac surgery. To further bring down operative mortality and morbidity, in patients with acutely ischaemic hearts, an optimal peroperative myocardial management is essential. LÄS MER

  5. 4. Interactive 3D Image Analysis for Cranio-Maxillofacial Surgery Planning and Orthopedic Applications

    Författare :Johan Nysjö; Ingela Nyström; Filip Malmberg; Ida-Maria Sintorn; Jayaram K. Udupa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical image analysis; interactive segmentation; volume rendering; computed tomography; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Modern medical imaging devices are able to generate highly detailed three-dimensional (3D) images of the skeleton. Computerized image processing and analysis methods, combined with real-time volume visualization techniques, can greatly facilitate the interpretation of such images and are increasingly used in surgical planning to aid reconstruction of the skeleton after trauma or disease.

  7. 5. Methodological improvements in quantitative MRI : Perfusion estimation and partial volume considerations

    Författare :André Ahlgren; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The magnetic resonance imaging (MRI) scanner is a remarkable medical imaging device, capable of producing detailed images of the inside of the body. In addition to imaging internal tissue structures, the scanner can also be used to measure various properties of the tissue. LÄS MER
