  1. 1. Electromagnetic Heating of Coated Ellipsoidal Gold Nanoparticles in Biological Tissue at Radio Frequencies

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Olle Hennert; Robert Themptander; [2023]
    Nyckelord :;

    Sammanfattning : Radiofrequency heating of gold nanoparticles for use in remote hyperthermia cancer treatment has seenrapidly growing interest in the last decade. While most of the focus has been on studying sphericalnanoparticles, a recent report suggests ellipsoidal particles can significantly increase heat absorption. LÄS MER

  3. 2. Simulation of Microwave Heating of Healthy and Cancerous Human Tissue With Gold Nanoparticles

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hampus Carlens; Mika Söderström; [2022]
    Nyckelord :Gold nanoparticle GNP ; Electrophoretic resonance; Dispersive permittivity; Cancer treatment; Waveguide; Radiotherapy; Graded material.;

    Sammanfattning : With a great need for new and better cancer treatments, microwaves and gold nanoparticles (GNPs) are increasingly being suggested to be used in radiotherapy. In thisreport, the authors present an investigation of how human tissue,both malignant and healthy, behaves under microwave radiation. LÄS MER

  4. 3. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Jules Reniaud; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. LÄS MER

  5. 4. Radiofrequency-Induced Heating of a Deep Brain Stimulator Lead inside TEM Cells and inside a 3T MR-Scanner

    Master-uppsats, Umeå universitet/Radiofysik

    Författare :Haider Shaban; [2022]
    Nyckelord :Medical Physics; MRI; ;

    Sammanfattning : The use of non-ionizing radiation in the magnetic resonance imaging (MRI) made it a safer diagnostic technique in comparison to the X-ray imaging method. MRI can also produce soft tissue images with a very high contrast without contrast agent which is another advantage that made MRI an important imaging technique for studying the mechanism of the deep brain stimulation (DBS) and for targeting the desired regions in the brain that should be stimulated.

  7. 5. In-vivo assessment of unwanted tissue heating during near infrared laser light emission

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Molin; [2020]
    Nyckelord :tissue heating; laser heating; NIR window; biophotonics; spectroscopy; Medicine and Health Sciences;

    Sammanfattning : In this work, potential adverse tissue heating in conjunction with near infrared (NIR) laser spectroscopy was studied. The tissue heating from laser light within the NIR optical window is currently a relatively unexplored field. LÄS MER
