QI: Theo Driever started his MSc project
On October 10th Theo Driever started his MSc project. Theo will work on methods to enhance the reproducibility of measures of functional connectivity in the brain and their dependence on different steps in the processing pipeline. This is done in order to increase the sensitivity to physiological aging as well as pathological development in the functional connectivity analysis. His supervisor is Frans Vos.

QI: Zhiyi Wu started her MSc project
Zhiyi started her MSc thesis on: "The joint method of image segmentation and registration" on November 23th. Zhiyi’s research will mainly focus on processing liver DCE-MRI datasets. A new joint registration and segmentation method will be developed not only to compensate the liver motion in DCE series but also to distinguish the liver from the image volume of the abdomen. Her supervisors are Tian Zhang and Frans Vos.

More insight into Crohn’s disease
Researchers Robiël Naziroglu and Frans Vos have developed a method for improving the assessment of MRI images in cases of Crohn’s disease. In time, this may well enable more targeted monitoring and treatment of this chronic intestinal inflammation. Naziroglu will take his doctorate on this subject at TU Delft on Monday 21 November.
From light spots to supersharp images
Making detailed 3D images of proteins in living cells with a special light microscope, without damaging those cells. That is what Sjoerd Stallinga, winner of an ERC Advanced grant worth 2.3 million euros, wants to achieve. In order to do so he is going to scan samples nanometer by nanometer using a sophisticated 3D light pattern in an approach that requires extensive collaboration between different disciplines.
Spotlight on aggressive cancer cells
Metastases in cancer are often caused by a few abnormal cells. These behave more aggressively than the other cancer cells in a tumour. Miao-Ping Chien and Daan Brinks are working together, from two different universities, on a method to detect these cells. Their research has now been published in Nature Biomedical Engineering
How to find structurally different molecules before they disappear in the average?
Particle fusion for single molecule localization microscopy improves signal-to-noise ratio and overcomes underlabeling, but ignores structural heterogeneity or conformational variability. This study presents a-priori knowledge-free unsupervised classification of structurally different particles employing the Bhattacharya cost function as dissimilarity metric.
The impact of noise on Structured Illumination Microscopy image reconstructions
Super-resolution structured illumination microscopy (SIM) has become a widely used method for biological imaging. Standard reconstruction algorithms, however, are prone to generate noise-specific artifacts that limit their applicability for lower signal-to-noise data. Here we present a physically realistic noise model that explains the structured noise artifact, which we then use to motivate new complementary reconstruction approaches.
A new tool to understand the brain
How does our brain work? An international team of researchers, including lead author Daan Brinks of TU Delft, has taken another step towards answering that question. They have created a new tool that allows them to image electrical signals in brains with an unprecedented combination of precision, resolution, sensitivity, and depth.
Researchers make 3D image with light microscope
For the first time, Delft researchers have succeeded in making a three-dimensional image of a cellular component using light. The component in question is the nuclear pore complex: tunnels that facilitate traffic to and from the cell nucleus. Studying cell components in 3D can help to determine the cause of various diseases, among other things. The researchers have published their findings in Nature Communications.
Decoding movement intentions in the brain using ultrasound waves
While many techniques can image brain activity, this was the first time that a new technology, called functional ultrasound imaging, was used to detect motor planning deep within the brain. The team is now applying functional ultrasound decoding to more complicated motor control tasks. At ImPhys, Dr. Maresca is developing ultrasound technologies to image brain activity down to the cellular scale.
