1. Ultrasound prediction of large fetuses. Epidemiological and clinical investigations
Abstract : The proportions of newborns with a birth weight (BW) >4,000 g and of macrosomic newborns (BW >4,500 g) have increased during the last two decades, parallel with an increasing maternal pre-pregnancy body mass index (BMI) and age at the time for pregnancy. Delivery of a large fetus, especially >4,500 g might cause perinatal complications for both the mother and her child. READ MORE

2. On perfusion estimation using ultrasound
Abstract : This thesis has the main focus on ways to improve the blood perfusion estimate, as obtained from a continuous wave Doppler system. Earlier studies have shown large temporal variations in the detected perfusion estimate, due to speckle. READ MORE

3. Quantification and Visualization of Cardiovascular Function using Ultrasound
Abstract : There is a large need for accurate methods detecting cardiovascular diseases, since they are one of the leading causes of mortality in the world, accounting for 29.3% of all deaths. READ MORE

4. Testing of Doppler Ultrasound Systems
Abstract : Blood and tissue velocities are measured and analyzed in cardiac, vascular, and other applications of diagnostic ultrasound. Errors in system performance might give invalid measurements.We developed two moving string test targets and a rotating cylinder phantom (Doppler phantoms) to characterize Doppler ultrasound systems.

5. Acoustic manipulation of cells and microbeads in droplet microfluidics
Abstract : Droplet microfluidics has emerged as a promising platform for miniaturisation of biological assays on-chip. In droplet microfluidics small water droplets (nL-pL) surrounded by an immiscible carrier oil are generated at high throughput. READ MORE
