  1. 1. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Giovanni Russo; [2023]
    Keywords : Laser speckle contrast imaging; Autofocus; Blind image sharpness assessment; Speckle noise; Perimed’s Perfusion Speckle Imager;

    Abstract : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. READ MORE

  3. 2. Mathematical modelling of microvascular oxygen transport and the impact of blood pressure

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Siri Walmstedt; [2023]
    Keywords : Mathematical modelling; Microcirculation; Oxygen transport; Blood pressure; Hypertension; Systems biology;

    Abstract : Cardiovascular diseases are the most common cause of death worldwide. There are known risk factorsfor cardiovascular diseases, such as high blood pressure, and it is also known that cardiovasculardiseases are associated with both the macrocirculation and the microcirculation.

  4. 3. The combination of SFDI with a mathematical model links perturbation in microcirculation to early stages of sepsis

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Caroline Korsfeldt; Sara Karajica; [2022]
    Keywords : SFDI; SFDS; mathematical modeling; sepsis;

    Abstract : The microcirculation system is crucial for the function of delivering biological markers such as oxygen and removing carbon dioxide from all the cells forming the complex ma- trix of tissue in the body. To keep up with the demands of each and every cell, there is a response from the microvasculature - resulting from for instance changes in blood flow to the tissue area. READ MORE

  5. 4. Semantic segmentation using convolutional neural networks to facilitate motion tracking of feet : For real-time analysis of perioperative microcirculation images in patients with critical limb thretening ischemia

    University essay from Linköpings universitet/Avdelningen för medicinsk teknik

    Author : Andreas Öberg; Martin Hulterström; [2021]
    Keywords : semantic segmentation; convolutional neural network; critical limb threatening ischemia; ROI tracking; deep learning;

    Abstract : This thesis investigates the use of Convolutional Neural Networks (CNNs) toperform semantic segmentation of feet during endovascular surgery in patientswith Critical Limb Threatening Ischemia (CLTI). It is currently being investigatedwhether objective assessment of perfusion can aid surgeons during endovascularsurgery. READ MORE

  6. 5. Capillary Blood Flow Measurement based on Nail-fold Microscopic Images using Feature Based Velocity Estimation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
