1. 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

2. Subharmonic Imaging of Polymer-Shelled Contrast Agents
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : The harmonic generation due to the nonlinear behavior of Ultrasound Contrast Agents (UCAs) must be exploited for improved efficiency when imaging vascular targets in the neighborhood of highly echogenic tissue. One may even further improve the efficiency by focusing on the subharmonic generation of the UCAs, which is an even more exclusive property than the generation of higher harmonics, for improved Contrast-to-Tissue ratio (CTR).

3. 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
