  1. 16. Optimization of measurement geometry for GASMAS lung function monitoring of infants

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Dennis Leander; [2018]
    Keywords : tissue phantom; premature infants; lungs; gas in scattering media absorption spectroscopy; tunable diode laser absorption spectroscopy; Physics and Astronomy; Medicine and Health Sciences;

    Abstract : A technique for measuring oxygen concentration in the lungs of preterm infants is one of the latest advancements in neonatal care. It is called GAs in Scattering Media Absorption Spectroscopy (GASMAS) and enables non-invasive, bed-side monitoring of the lung function of our most fragile patients, preterm newborns. READ MORE

  2. 17. Skin dose measurement during radiation therapy of mastectomy patients using GafChromicTM EBT3 films.

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Madeleine Bergström; [2017]
    Keywords : Mastectomy; Radiation therapy; GafChromic; EBT3; microcirculation;

    Abstract : Purpose: The aim of this study was to develop a method of measuring changes in the skin microcirculation and skin dose for mastectomy patients in connection with the radiation treatment. The distribution of the skin dose, its dependence on the energy of the beam, field geometry and bolus material and the accuracy of the given skin dose in the treatment planning system were studied.

  3. 18. Hardware Control of a Near Infrared Fluorescence System : LabVIEW Programming and Evaluation

    University essay from Linköpings universitet/Biomedicinsk instrumentteknik

    Author : María Martha de la Paz Velasco Santoscoy; [2016]
    Keywords : Near-infrared; indocyanine green ICG ; biomedical optics; fluorescence; spectroscopy; lasers.;

    Abstract : Indocyanine green (ICG) is a fluorescent dye used as an indicator in medicine and surgery. The maximum absorption wavelength of ICG is at 785 nm, while the maximum emission is around 820 nm. ICG is nontoxic and is rapidly excreted into the bile. READ MORE

  4. 19. Diode laser spectroscopy for oxygen detection in the lungs of infants

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Peilang Liao; [2016]
    Keywords : GASMAS; Tunable laser; Transport theory; 3D phantom; Diagnoses; Gas; Lung; Physics and Astronomy;

    Abstract : This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments.

  5. 20. Kalman Filter Based Approach : Real-time Control-based Human Motion Prediction in Teleoperation

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Zheyu Jerry Fan; [2016]
    Keywords : Human Computer Interaction HCI ; Kalman Filter Algorithm KFA ; Linear Kalman Filter LKF ; Extended Kalman Filter EKF ; Network delay; Virtual Reality VR ; Haptic; Telepresence; Teleoperation; Human Motion Prediction; Human Motion Tracking;

    Abstract : This work is to investigate the performance of two Kalman Filter Algorithms, namely Linear Kalman Filter and Extended Kalman Filter on control-based human motion prediction in a real-time teleoperation. The Kalman Filter Algorithm has been widely used in research areas of motion tracking and GPS-navigation. READ MORE
