To diagnose cancer a range of imaging techniques are used, such as MRI, CT and ET scans. However, ultrasound has the advantages of being a real-time, portable, widely available and cost-effective alternative. TU/e-researcher Anastasiia Panfilova investigated two promising ultrasound techniques, and developed an ultrasound contrast agent that can act as a therapeutic by delivering medication locally to tumors. On Tuesday 18th of January Panfilova will defend her Ph.D.-thesis at the department of Electrical Engineering.
