Synthetic Aperture Compound Imaging

Medical ultrasound imaging is used for many purposes, e.g. for localizing and classifying cysts and tumors. A major drawback of ultrasound imaging is the low contrast due to the presence of speckle artifacts. A successful approach to remedy this is spatial compounding, where images are acquired from different directions and combined. The resulting images have a reduced speckle appearance, but at the cost of a reduced frame rate.

This project develops methods to perform spatial compounding using synthetic aperture data acquired with the experimental ultrasound scanner SARUS. It is investigated how to obtain a reduction in speckle appearance without a reduction in frame rate as well as how to increase the resolution using motion compensation. The methods are evaluated through phantom studies and in pre-clinical trials.

Synthetic aperture compounding should be able to obtain high contrast images allowing for an early detection of cysts and tumors.
