  1. 1. Acoustic Droplet Vaporization : An Assessment of How Ultrasound Wave Parameters Influence the Vaporization Efficiency

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Sara Öquist; [2020]
    Nyckelord :Acoustic Droplet Vaporization; Verasonics; Ultrasound; Vaporization Efficiency; Phase-change Contrast Agents;

    Sammanfattning : Acoustic droplet vaporization (ADV) is a process in which a phase shift of a liquified droplet into a gaseous microbubble, is triggered using an ultrasonic wave. In contrast to utilizing conventional contrast agents in ultrasound, the phase change contrast agents used in ADV can extravasate into tumor tissue, and they offer a greater circulatory lifespan, thereby increasing the potential applications in which they can be utilized.

  3. 2. Acoustic Droplet Vaporization of Perfluorocarbon Filled Microdroplets

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Didrik Nimander; [2019]
    Nyckelord :Medical engineering; Acoustic Droplet Vaporization; Ultrasound; Contrast agent;

    Sammanfattning : The use of peruorocarbon lled droplets for use as Phase Changing Contrast Agents (PCCAs) is a promosing eld. These capsules also have potential to be used for mediated drug delivery. The phase change, which has given the capsules their name, is the process when the capsule transforms from a droplet into a bubble. LÄS MER

  4. 3. Development of Ultrasound Pulse Sequences for Acoustic Droplet Vaporization

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Isabelle Gouwy; [2019]
    Nyckelord :Ultrasound; Ultrasound contrast agents; Phase-change contrast agents; Acoustic droplet vaporization; Verasonics;

    Sammanfattning : Ultrasound-mediated drug delivery has been proposed as a safe and non-invasive method to achieve localized drug release. Drug-loaded microbubbles are injected in the vascular system and ultrasound waves are then used to localize and burst the microbubbles at a specific targeted area. LÄS MER
