Short Description
Over the past 15 years, microbubbles have emerged as an appealing contrast agent for ultrasound imaging. They are typically composed of a thin shell – often a lipid monolayer – that is surrounding and stabilizing a gas core. Image contrast derives from nonlinear backscattering of acoustic waves upon exposure to acoustic pressure - a result of microbubble size oscillation that depends on microbubble size and other properties. We aim to design a process to detect differences in acoustic responses of functional microbubbles using an ultrasound imaging probe.
Goal & Tasks
The goal of the project is to design an imaging mode that can visualize different functional microbubbles within an ultrasound image. The main tasks of this project are:
- Literature study of current microbubble imaging techniques
- Design an imaging technique for our given setup
- Verify the designed technique using simulations
- Implement the designed technique on one of our ultrasound imaging systems
- Verify the designed technique in an in-vitro setup
