  1. 1. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Björn Walter; Stefan Piiroinen; [2021]
    Nyckelord :Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

    Sammanfattning : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.

  3. 2. Needle Navigation for Image Guided Brachytherapy of Gynecologic Cancer

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Alireza Mehrtash; [2019]
    Nyckelord :Image Guided Surgery; Surgical Navigation System; Needle Navigation system; Brachytherapy; MRI; 3D Slicer;

    Sammanfattning : In the past twenty years, the combination of the advances in medical imaging technologies and therapeutic methods had a great impact in developing minimally invasive interventional procedures. Although the use of medical imaging for the surgery and therapy guidance dates back to the early days of x-ray discovery, there is an increasing evidence in using the new imaging modalities such as computed tomography (CT), magnetic reso- nance imaging (MRI) and ultrasound in the operating rooms.

  4. 3. Exploring the LASSO as a Pruning Method

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Leo Ekbom; [2019]
    Nyckelord :neural networks; pruning; lasso; group lasso; obd; Physics and Astronomy;

    Sammanfattning : In this study, the efficiency of various pruning algorithms were investigated, with an emphasis on regularization methods. Pruning is a method which aims to remove excess objects from a neural network. LÄS MER

  5. 4. An experimental analysis regarding neural bases of hand synergies during reach-to-grasp movements

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Alexander Warsi; Jessica Ericsson; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Traumatic brain injury and diseases causing cortical damage is a global problem. Despite their vast extent, their pathophysiology is poorly understood. It is however known that the loss of motor functions can be regained thanks to adaptive properties of the neuronal system. LÄS MER

  7. 5. MÄTNING AV SYNNERVENS FUNKTION

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Mirushe Mjekiqi Istrefaj; [2018]
    Nyckelord :Visual evoked potentials VEP ; P100; multipel skleros MS ; Nervus opticus; Optikusnerutit; Latens; Normalvärde;

    Sammanfattning : Visual Evoked Potentials (VEP) är en elektrofysiologisk undersökningsmetod som används inom klinisk neurofysiologi. Undersökningen görs för att analysera synnervsfunktionen. Metoden går ut på att mäta den tid det tar för synbarken att registrera visuella synintrycken som näthinnan utsätts för. LÄS MER
