With recent advancements in autonomous driving, the demand for precise and accurate perception systems has increased. Perception of the vehicle’s environment is a key element in ensuring safe operation. Due to their wide aperture angle and low cost, ultrasonic sensors are a viable option for achieving close-range 360° perception around the...

Evaporation can induce acoustic emissions in microfluidic devices. The origin of these emissions and their damping remains elusive. This thesis studies acoustic emissions from 3D printed microfluidic tubes mimicking xylem vessels in plants. We show the time and frequency domain signature of these emissions. From these signatures, we identify...

Current research on osteoporosis detection and transcranial imaging suggests that it is necessary to find a method to calculate the speed of sound in curved bones. A popular method to find the speed of sound in bones is by the bidirectional axial transmission technique. Currently, this method assumes that the arrival time of the head wave...

Neuromodulation of the vagus nerve is used as a treatment for all kinds of ailments and even as a means of improving the wearer's physiology, however, this form of treatment is not popular due to its invasive nature, high chance of side effects, and short period between reimplementation surgery, as such an alternative is sought in the form of...

In orthopaedic and dental surgery, bone grafts are used by surgeons as substitutes for the patient’s own bone. A bone graft provides support to the skeletal structure and stimulates the ingrowth of new bone. There is a growing demand for bone grafts due to an increasing world population and an ageing demographic. Tissue banks produce bone grafts...

The main objective of this thesis is to design a transmitter channel which is implemented in a 2D phased-array ultrasound neuromodulation system aiming for the vagus nerve stimulation. The vagus nerve has the widest distribution in the parasympathetic system and it oversees several important bodily functions such as the control of mood, immune...

Mooring chains are subject to dynamic loads and corrosion. A challenging aspect in assessing the integrity of mooring chains is the presence of marine growth. Marine growth removal is expensive, environmentally damaging, and includes the risk of restarting corrosion process. The focus of this research is on the feasibility of mooring chains...

Introduction: Uveal melanoma is the most frequently occurring primary eye tumour. The aim of this research was to determine the difference in geometrical tumour measurements between ultrasound and magnetic resonance imaging (MRI), to compare MRI and ultrasound-based tumour models, and to evaluate the clinical implications of these differences...

An ASIC is presented for intra-vascular ultrasound imaging. Despite being connected via a single coaxial cable, it is able to pass arbitrary high voltage bipolar signals to the transducers for acoustic imaging. The thesis talks about the need to reduce the cable count to one and reviews the existing work in literature. It builds up on an...

Implantable Medical Devices (IMDs) could fulfill many different functions in the human body. Batteries have always been the main power source of these devices. Batteries have some drawbacks, the biggest one being the replacement of IMDs with fully discharged batteries. In this thesis a wireless power transfer system, with a receiving power...

Concrete is the most widely used building material in the world and its stability assessment is of utmost importance for society. Ultrasonic measurements are one tool for investigation of concrete stability. The goal of those measurements is the derivation of damage sensitive parameters. The way ultrasound diffuses through concrete is affected...

Neurostimulators have been developed over the past few decades to treat various diseases, such as Parkinson’s disease, chronic pain, epilepsy, migraine and bladder dysfunction. One of the major design challenges is the selection of a powering method that could supply mW power levels to miniaturized implanted devices. Among several methods,...

Ultrasound gives the opportunity to look at muscles and observe their change in length. This tool has increased the knowledge about muscle-tendon dynamics and sometimes revealed surprising muscle stretch behaviour. System identification experiments use robots to disturb the ankle and measure its torque and angle. Muscle movement is derived from...

Osteoarthritis is a degenerative disease of the joints that reduces physical function and leads to chronic pain. It occurs mostly in persons from an age of 50 years of older and can be considered a disease of the aging population. Although there is no clear evidence of its effects, induced hyperthermia is sometimes prescribed to these patients...

Miscannulation during dialysis is the cause of shunt damages such as scarring, narrowing, blocking, infection and internal bleedings. Miscannulations increase the difficulty of flawless puncturing next time and in general reduce the shunt’s lifetime, leading to more invasive surgeries and higher costs. Ultrasound devices are used to simplify the...

Due to the increasing prevalence of obesity and type 2 diabetes, the occurrence of liver disease has also increased. In the last decade, important improvements have been realised in methods to treat liver disease, especially in the field of image-guided minimally invasive procedures. With the rapidly developing field of minimally invasive...

Background: An ablation catheter with integrated high-frequency single element ultrasound transducers has been developed by Philips Research, which makes it possible to assess tissue-depth and lesion formation in real-time. The interpretation of the acquired ultrasound M-mode images is difficult due to a combination of cardiac motion and motion...
