MSc thesis project proposals

Here is a list of possible MSc thesis projects. This is intended just to give an idea, actual projects are usually defined after discussion with the advisor.

Development of a fully coupled FEA-based transducer model

The recently established Modeling and Simulation Department at Sonion has a young and rapidly growing team with the goal to model and design innovative products for the hearing aid and pro-audio industry, such as miniaturized loudspeakers and other transducers used also in many modern consumer electronics products like smart phones, ear buds, tablets. In case of hearing aids, transducers are the main active components, and their behavior is crucial for the hearing aid performance. Therefore, a good dynamic model able to predict the behavior of the transducer under different conditions is required in order to test new designs, optimize the sound quality and reduce the product size.

The aim of this project is to develop a CMOS based Hall sensor without offset.

Ex-Situ Heart Perfusion (ESHP) sensor

The aim of this project is to develop an optical sensor to monitor the quality of heart cells during transplantations or during surgery. The rate of success of cardiac transplants largely depends on the amount of damage to the heart cells (myocardial ischemia). The use of ESPH (Ex-Situ Heart Perfusion) during transport, or while waiting for transplantation, enables the in-line monitoring of the quality of the donor heart muscle cells. Measuring the heart cell metabolism in strategic places, using several miniature sensors, would be of great value for more successful cardiac transplants.

Analysis of 3D right ventricular shape from echocardiography

The functioning of our hearts is of vital importance to physical wellbeing. The right half of the heart is responsible for collecting the returning blood from the main circulation and pumping it to the lungs, where it is resupplied with oxygen. When the functioning of the right ventricle is compromised, venous pressure will rise and lung function will be decreased, leading to severe health problems on the long term.

Volumetric photoacoustic imaging of kidney

Photoacoustics (PA) is a rapidly developing imaging modality which provides information about the molecular composition of biological tissue. The photoacoustic signal is generated by so-called chromophores, such as biological molecules that absorb light, which can transform absorbed light into an ultrasound signal. The presence of certain types of chromophores can be a valuable marker indicating the condition of biological tissue. The accurate quantification of certain types of chromophores can improve clinical diagnosis. However, at each moment, only a limited area of human tissue can be exposed by a light (laser) which impedes volumetric analysis of present chromophores. The goal of this project is to quantify present chromophores in large organs, e. g. kidney, which are normally challenging to be fully imaged with PA.

Photoacoustic techniques for plaque detection

Atherosclerosis is a progressive inflammatory disease that is characterized by the accumulation of lipids in the artery wall. The composition withholds information about the risk of it causing a cardiovascular event. Currently used imaging techniques in carotid atherosclerosis provide mostly morphological information and lack molecular information.

Conditioning Navier-Stokes based velocity field regularization with sparse high-fidelity data

Vector flow imaging (VFI), a relatively recent development in diagnostic ultrasound research, describes a group of flow imaging methods that quantify both the magnitude and angle of the blood velocity vectors in the organ of interest (e.g. the heart). This is in contrast to traditional Doppler ultrasound which only estimates the velocity component on the axis towards the transducer.

The effect of fast microbubble motion on contrast pulse sequences

Ultrasound contrast agent (UCA), most commonly in the form of 1-10 µm microbubbles consisting of a lipid-monolayer shell with an inert gas core, are used to opacify the blood pool in ultrasound imaging. A more recent application of UCA is as tracer agents for echo-particle image velocimetry (echoPIV) where high frame-rate ultrasound imaging is used to track the motion of the microbubbles as they flow with the blood.

[2021] Body Coupled Communication for Microscale Implants

This project aims to investigate the applicability of body-coupled communication (BCC) for a network of micro-scale implants. The project's main goal is proposing and implementing a lightweight network protocol suitable for implantable micro-scale devices and/or implementation of an energy-efficient tissue interface for the BCC method.

Self-test for IR Sensors

In many applications, the lens and packaging of IR sensors can become contaminated leading to measurement error and apparent failure. A self-test built into the package could solve this problem. This project concerns the development of a self-test system which can compensate for minor contamination and produce a warning for higher contamination levels.

Hernia post-operative monitoring

Incisional hernia (IH) is a complication which can occur after surgery to the abdomen. In order to prevent IH, a mesh can be used. This holds the tissue in place to reinforce it and to enable healing. However, in some cases the healing does not take place correctly and IH is not prevented. In order to monitor healing, scans or ultrasonography can be used, but these diagnostic tools are expensive and time consuming. The aim of this project is to create a “bionic” mesh which can detect the early stages of IH formation with a device attached to the tissue around the wound.

Modelling for fontain circulation in congential heart disease

Children born with a single-ventricle heart defect need a series of operations, otherwise they will die in the first week of their life. Since the dysfunctional ventricle cannot be repaired, surgeons connect the functional ventricle to the aorta and the venous blood flow is redirected such that it passively returns to the lungs, thereby bypassing the heart. The final result is a so called Fontan circulation (Figure left panel). Patients with a Fontan circulation often suffer from limited exercise capacity, which is thought to be related to the geometry of and the altered hemodynamics in the Fontan circulation. Moreover, these patients use medication their entire life to avoid blood clotting.
