Medical ultrasound is a popular imaging modality in cardiology. Harmonic Imaging is a technique that has been shown to increase the image quality of diagnostic ultrasound at frequencies below 10 MHz. However, Intravascular Ultrasound, which is a technique to acoustically investigate arteries from within the lumen by means of a catheter, typically transmits at higher ultrasound frequencies ( >20 MHz). This dissertation describes studies showing the feasibility and potential of Harmonic Imaging for Intravascular Ultrasound. Harmonic Intravascular Ultrasound can reduce undesired image artefacts, and shows the potential to detect ultrasound contrast agents from within the lumen. This makes Harmonic Intravascular Ultrasound a promising tool in cardiovascular research.
