  4. 8. Acoustic Focusing of Lysozyme Crystals

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Måns Junestrand; [2023]
    Nyckelord :Protein Crystals; Lysozyme Crystals; Ultrasound; Acoustic Focusing; SFX; Biomedical Physics; Proteinkristaller; Ultraljud; Lysozymkristaller; Akustisk fokusering; SFX; Biomedicinsk fysik;

    Sammanfattning : Acoustic focusing of microscale protein crystals with acoustophoresis technology could reduce clogs during experiments with the scientific technique serial femtosecond x-ray crystallography (SFX). SFX determines molecular structures of proteins, these structures are valuable in drug discovery and fundamental biomedical research. LÄS MER

  7. 10. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER
