  1. 11. General Defocus Particle Tracking

    University essay from KTH/Tillämpad fysik

    Author : Joakim Anderberg; [2023]
    Keywords : General Defocus Particle Tracking; ultrasonic standing waves; microscopy; microchip; single plane particle tracking; levitation; Generel ur-fokus partikel spårning; stående ultraljudsvågor; mikroskopi; mikorchip; enkelplans partikel spårning; levitation;

    Abstract : Three-dimensional particle tracking is a valuable tool in microfluidics for obtaining information about a system. General Defocus Particle Tracking (GDPT) is a straightforward method of 3D particle tracking that only requires a single-camera plane, making it applicable to existing equipment in a laboratory.

  3. 12. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Johansson Vivika; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

  5. 14. Why should 3D Gait Analysis be included in the Walking Pattern Assessment of individuals with Spinal Cord Injury? : Biomechanical analysis of gait and gait patterns in individuals with spinal cord injury

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

    Author : Chiara Pollicini; [2022]
    Keywords : Spinal cord injury; 3D gait analysis; gait features; GDI; GPS; Clinical assessments; ASIA scale;

    Abstract : Background: The yearly incidence of people with Spinal Cord Injury (SCI) is between250,000 and 500,000, according to the World Health Organization (WHO). The injury often reduces the ability to walk. Various consequences affect the nervous system and, thus, the entire body. READ MORE

  6. 15. Using Optical Flow to provide robustness for animage sensor based multiangulation positioning system

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Fredrik Anderson; [2022]
    Keywords : ;

    Abstract : The use of image sensors in positioning systems has increased significantly the last years, spanning from complex SLAM-systems to simpler triangulation based methods. In the latter case, occlusion of anchor points may render the triangulation unsolvable, and any practical implementation must address this problem. READ MORE
