1. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)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

2. Speckle suppression in ultrasound images of heterogeneous materials
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : Performing non-destructive testing (NDT) on materials is a helpful tool for maintenance and quality control because the materials are not destroyed or disturbed; ultrasound imaging is one type of NDT. Ultrasound imaging of heterogeneous materials contains many echoes from the material itself. READ MORE

3. Detection of local motion artifacts and image background in laser speckle contrast imaging
University essay from Linköpings universitet/Institutionen för medicinsk teknikAbstract : Laser speckle contrast imaging (LSCI) and its extension, multi-exposure laser speckle contrast imaging (MELSCI) are non-invasive techniques to monitor peripheral blood perfusion. One of the main drawbacks of LSCI and MELSCI in clinical use is that the techniques are sensitive to tissue movement. READ MORE

4. Quantification and Detection of Motion Artifacts in Laser Speckle Contrast Imaging
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Laser speckle contrast imaging (LSCI) is a non-invasive method for assessment of microcirculatory blood flow. The technique is based on analysis of speckle patterns to build 2D maps of perfusion with high spatial and temporal resolution. READ MORE

5. 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 teknikAbstract : 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
