1. Ultrasound Imaging Velocimetry using Polyvinyl Alcohol Shelled Microbubbles
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Current research within the field of ultrasound contrast agents (UCAs) aims at developing capsules which are not only acoustically active, but also have a chemically modifiable surface. This enables use in new areas, including targeted drug delivery and theranostics. READ MORE

2. Implementation of Super-Resolution Ultrasound Imaging for in Vitro Experiments
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Ultrasound imaging systems are a safe and affordable imaging modality with the disadvantage of low spatial resolution, especially for assessing smaller vessels. However, with the implementation of super-resolution ultrasound imaging techniques, studies have shown promising results in achieving a resolution below the diffraction limit. READ MORE

3. Development of a Tool for Imaging the Pumping-Out Behavior of Poly- Vinyl Alcohol Shelled Microbubbles
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : For many years, microbubbles have been used as ultrasound contrast agents to improve the quality of diagnostics, seeing that they produce more backscattering ultrasound than blood does. Novel types of microbubbles and increased knowledge about their different behaviors have led to other suggested areas of use. READ MORE

5. Ultraharmonic Imaging of Polymer-shelled Microbubbles
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Ultrasound has been established as one of the most widely used imaging modalities for diagnostic purposes, due to the several advantages it provides in comparison with other techniques. Hence, ways to further improve the confidence in diagnoses provided by ultrasound are constantly being investigated. READ MORE
