Fran will work with scatteromety for nanoparticle detection. His supervisors are Silvania Pereira and Dmytro Kolenov.

The field of optical microscopy research has developed rapidly in recent years. Thanks to the invention of a technique called super-resolution fluorescence microscopy, it has recently become possible to view even the smaller parts of a living cell. Now, by making a smart refinement to that technique, researchers at TU Delft have pushed its boundaries even further. Where previously objects measuring up to 10-20 nanometres could be observed, their method makes it possible to focus on structures of as tiny as 3 nanometres across.

In this article, a sparsity‐inducing scheme based on widefield stimulated emission depletion, which requires stringent control of the polarization state of both the excitation and depletion laser, is introduced by Bernd Rieger and co‐workers for superresolution fluorescence microscopy. The ideal state involves excitation and depletion lasers with linear polarizations, orthogonally oriented in the sample plane. This state is obtained from linearly polarized light from the laser, which is made elliptically polarized before reflecting off the dichroic mirror.

He will work on “particle averaging” techniques for single molecule localisation microscope. He will continue the work of Hamidreza Heydarian where we successfully introduced this idea. His first task will be to extend the method from 2D to 3D. His supervisors will be Sjoerd Stallinga and Bernd Rieger.

We would like to welcome our new master student Marten Kruidhof. He will work on “Acoustic imaging of a simple phantom using a silicon ring-resonator sensor for ultrasound.” His supervisors are Boling Ouyang and Jaap Caro.

Jim Aspers started his MSc project on "High Volume Rate 3D Compressed Ultrasound Imaging Using a Programmable Transducer Array". His supervisors are Martin Verweij and Fabian Fool.

Joanne will investigate whether and how the reflections of the second harmonic of an ultrasound field can be used for medical model based imaging. The second harmonic is the first of a whole series of higher harmonics that are generated during the nonlinear propagation of a high-amplitude ultrasound pulse as used in medical imaging. Her supervisors are Martin Verweij and Jack Massaad.

Researcher Maysam Shabanimotlagh has brought important improvements in ultrasound measurement a step closer. On Wednesday 12 September, he will be awarded his PhD at TU Delft for his work on this technology.

Claudio is a master student in Life Sciences at the University of Applied Sciences and Arts Northwestern Switzerland. The ultimate goal of this master project is to achieve transcranial ultrasound image quality sufficient to reliably differentiate various anatomical structures in intact human brain as well as the location of the deep brain stimulation electrodes in respect to those anatomical structures (e.g. subthalamic nucleus). His supervisor is Verya Daeichin.

Delft Bioengineering Institute has granted Elizabeth Carroll with €2500 for the execution of an interdisciplinary MSc project. Together with Zoltán Perkό (Radiation Science & Technology), Elizabeth has designed a project that looks into ultrahigh dose-rate FLASH irradiation in zebrafish. In total, BEI has granted 15 MSc projects that resulted from the networking event BioDate 2018 in March.
