1. 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

2. The effect of mechanical ventilation on abdominal organs : Analysing the role of PEEP and perfusion
Abstract : Background: The effect of mechanical ventilation on abdominal organs is not well understood and investigated yet. Previous studies, using an animal sepsis-like model, found an association between mechanical ventilation (MV) and abdominal edema and inflammation. READ MORE

3. Movement artifact reduction in laser Doppler blood flowmetry : myocardial perfusion applications
Abstract : Laser Doppler perfusion monitoring (LDPM) and imaging (LDPI) enable assessment of tissue microvascular perfusion. The techniques are based on the Doppler broadening of the optical spectrum occurring when coherent laser light is scattered by moving red blood cells (RBC). READ MORE

4. Tools for the development of intensified perfusion processes for mammalian cell culture
Abstract : Recombinant protein therapeutics have become an indispensable part of modern medicine to treat a wide variety of diseases. Their manufacture is mostly based on mammalian cells with fed-batch production bioreactors and downstream batch purification unit operations. READ MORE

5. WAVELET NOISE REDUCTION AND VASCULAR WATER TRANSPORT MODELLING : APPLICATIONS TO DIFFUSION AND PERFUSION MRI
Abstract : Magnetic resonance imaging (MRI) is a powerful medical imaging technique, used to detect and characterise a range of diseases and conditions. It is based on the use of a strong static magnetic field in combination with magnetic field gradients and pulsed radiofrequency electromagnetic fields to visualise various organs and structures in the body according to their morphology or function.
