The Department of Imaging Physics (ImPhys) focuses on developing novel, sometimes revolutionary, instruments and imaging technologies. These research products extend existing boundaries in terms of spatial resolution, temporal resolution, and information/data throughput. We are pioneers in developing advanced concepts of computational imaging, a marriage between cleverly designed imaging systems and sophisticated post-processing.
ImPhys’s profile encompasses a mix of science, engineering and design. While the spectrum of imaging physics is very broad, we focus on a few key fields where we generate impact: Life sciences, Healthcare and High tech industry.

A New Beam Multiplexer for NASA's GUSTO mission
GUSTO, NASA's stratospheric balloon observatory, will bring the Dutch multi-pixel camera system of SRON and TU Delft to the edge of space. It will perform a large-scale observation of the spectral lines from ionized atoms between the stars of the Milky Way. As an extra hardware contribution, SRON-TU Delft delivers a Fourier phase grating. The technique behind it is now published in Optics Express.

Chris den Ouden joined ImPhys as MSc student
Chris den Ouden has started a M.Sc. project under supervision of Eric Verschuur. He will work on direct inversion of seismic reflection measurements into physical subsurface parameters using Machine Learning approaches, under a local horizontally layered medium assumption. The use of prior knowledge from borehole data will be important to steer the ML process via training on synthetic data and, thereby, reduce the ambiguity.

AWI: Farewell Aramco Overseas
Since 2012 Saudi Aramco has located one of their Global Research Centers inside our university. To extend their activities, they have chosen for a new office location at Delftechpark. As this is still close to our university, the intensive research cooperation in the field of oil and gas exploration and monitoring will remain unchanged. The main task of the Aramco Research Center in Delft is to improve seismic data processing to get a sharper image of the subsurface, which allows it to obtain more reliable information upon which drilling decisions can be based. With backgrounds in math, physics and software development they have strong relationships with our acoustical imaging research group (AWI), as we develop cutting-edge technology for the oil and gas industry within the framework of the Delphi consortium, for which Saudi Aramco is one of the sponsors. We would like to congratulate Saudi Aramco with their new office and are looking forward to a fruitful continuation of our cooperation.

QI: Paper Jianfei Yang (PhD) published on PLOS ONE
His paper presents and studies a framework for reliable modeling of diffusion MRI using a data-acquisition adaptive prior.
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.
IRIS Lab: AI for quantitative bioimaging
The aim of the IRIS lab is to open the black box of AI and develop methodologies for context-independent, knowledge-based learning of imaging systems that will address fundamental challenges in all quantitative imaging applications. The proposed AI-technology will be applied to electron, optical, and ultrasound imaging to unravel dynamic molecular processes in living organisms: conformational ensembles of proteins, single-molecule dynamics in thick tissue and super-resolved vasculature mapping in real-time.
An all-time high for far-infrared space exploration
Next year, a helium balloon the size of a soccer stadium will bring a NASA telescope to the edge of space. This project is called GUSTO, and it will help scientists understand galactic evolution by probing interstellar gas. Its most important payload are three detectors developed by Jian Rong Gao and his teams at TU Delft and SRON, without which the telescope would be blind as to its mission purpose.
