  1. 6. Diffusion-Based MR Methods for Measuring Water Exchange

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Shan Cai; [2022]
    Keywords : diffusion MRI; water exchange rate; membrane permeability; double diffusion encoding; DDE;

    Abstract : Measuring transmembrane water exchange can provide potential biomarkers for tumors and brain disorders. Diffusion Magnetic Resonance Imaging (dMRI) is a well-established tool that can non-invasively measure water exchange across cell membranes. Diffusion Exchange Spectroscopy (DEXSY) is one of the dMRI-based frameworks used to estimate exchange. READ MORE

  3. 7. Antenna Implants and Feasibility of Performance Limitations : AStudy of Radiation Efficiency on Electrically Small Antenna Implants with Finite Conductivity and Size

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

    Author : Erik Algarp; [2022]
    Keywords : Antennaimplant; Medical Implant CommunicationSystem; Electrically small antenna; Electric dipole; Magnetic dipole; Fundamental bounds; Performance limits; Radiation efficiency; Conductor loss; Antennimplant; Medical Implant Communication System; Elektriskt små antenner; Elektrisk dipol; Magnetisk dipol; Fundamentala begränsningar; Prestandagränser; Strålningseffektivitet; Metallförlust;

    Abstract : Antenna implants are used to establish a telemetry link to enable wireless data transfer, suitable for telemedicine and other medical applications. Inbody environments with water-based tissues lead to severe power absorption, making signal strength and radiation efficiency challenging yet central performance aspects of antenna implants.

  4. 8. Utveckling av Polydimetylsiloxan-Mikropartiklar för Biomedicinsk NMR

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Mohammad Al-Sultani; Josef Djärf; [2022]
    Keywords : Technology and Engineering;

    Abstract : Nuclear magnetic resonance spectroscopy is a technique for identifying molecular structures, compositions etc. and is widely used in many life science research fields. The purpose of this project is to synthesize PDMS microparticles with a magnetic susceptibility matching water, which makes them applicable for use in NMR of biological samples. READ MORE

  5. 9. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Author : Louise Olausson; [2022]
    Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

    Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

  6. 10. Verification measurements on MRI-linac with PTW BEAMSCAN MR

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olivia Kvarnlöf; [2022]
    Keywords : ;

    Abstract : In radiotherapy the main goal is to kill cancer cells, prevent them from growing and reproducing, while healthy tissue is spared. One technique to treat cancer is to use external radiotherapy where a linear accelerator (linac) is used to generate a high energy radiation photon beam. READ MORE
