6. Acoustic Characterization of the Frequency-Dependent Attenuation Profile of Cellulose Stabilized Perfluorocarbon Droplets
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : The use of ultrasound contrast agents increases the information available for reconstruction during ultrasound imaging. Previously studied microbubbles, consisting of a gas core, are subject to limitations such as a short lifetime and a large size. READ MORE

7. Non-destructive Evaluation of Ultrasound Contrast Agent
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Clinical ultrasound imaging techniques can be greatly improved by the use of ultrasound contrast agents (UCAs). While microbubbles (MBs) without shell are unstable and cannot be used for practical applications,a shell produced from biocompatible polyvinylalcohol (PVA) significantly improves chemical versatility and stability.

8. Acoustic Droplet Vaporization of Perfluorocarbon Filled Microdroplets
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : 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. READ MORE

9. Development of Ultrasound Pulse Sequences for Acoustic Droplet Vaporization
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : 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. READ MORE

10. Study of the preparation of a stable foam
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : On a daily basis, abdominal examinations with x-ray imaging are run at hospitals for diagnosis of abdominal diseases. To enable doctors to visualize organs and tissues on an x-ray image with colors based on the radiodensity, the patient needs to drink an oral contrast that fills up the digestive system. READ MORE
