As a Postdoc at TU Delft, you will develop a novel type of radiation detector that opens up new possibilities for the image-guided treatment of cancer.
C-arm X-ray imaging is the dominant imaging modality in interventional procedures. Unfortunately, C-arms lack the rich information provided by diagnostic hybrid scanners such as PET/CT and SPECT/CT, which hinders image-guided interventions from becoming more efficient and effective. As a Postdoc within the section Medical Physics & Technology of TU Delft (, you will develop a novel detector technology that uses new scintillation materials, solid-state light sensing technology, high-bandwidth readout electronics, and real-time signal processing. These new detectors will enable the simultaneous detection of X-ray and gamma-ray photons, opening up the possibility of developing C-arms with combined X-ray and nuclear imaging capability.

Job description

MP&T's mission is to develop better technologies for the personalized diagnosis and treatment of disease, focusing on radiation-based approaches in medical imaging, radiation oncology, and image-guided interventions. We execute this project as a partner in the IMAGIO consortium, which recently secured funding from the EU Innovative Health Initiative to develop novel imaging and advanced guidance solutions in interventional oncology.


You will collaborate with industrial and clinical partners, including Philips and UMC Utrecht. Your research work will entail a mix of theoretical modelling and experimentation and is expected to result in detector prototypes that can be tested under clinically representative conditions. This project gives you the opportunity to contribute to the development of an innovative detector technology that can be integrated into existing infrastructure and used in a wide range of clinical applications. 


Delft University of Technology (TU Delft)


We are looking for enthusiastic and creative scientists who are motivated to push the limits in medical imaging instrumentation. You will be based at the section Medical Physics and Technology (MP&T) of the Radiation Science & Technology (RST) department of the Faculty of Applied Sciences of Delft University of Technology (TU Delft) and work closely together with colleagues from the industrial and clinical partners involved in the IMAGIO project.


Applicants must have a PhD in Physics or similar discipline. We are looking for candidates with a proven track record in experimental physics, instrumentation development, data acquisition, and signal processing. Experience in topics directly relevant to the project, such as ionizing radiation physics, radiation detection technology, analog and digital electronics, etc., is a plus.


Good communication skills and excellent English are required. You should possess a pro-active, independent, problem-solving, and result-oriented work attitude. Successful candidates are expected to publish their results in peer-reviewed scientific journals and actively participate in international conferences. 

Conditions of employment

Fixed-term contract: 36 months.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. The TU Delft offers a customisable compensation package, a discount on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged.

For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation. An International Children's Centre offers childcare and there is an international primary school.


Delft University of Technology

Delft University of Technology is built on strong foundations. As creators of the world-famous Dutch waterworks and pioneers in biotech, TU Delft is a top international university combining science, engineering and design. It delivers world class results in education, research and innovation to address challenges in the areas of energy, climate, mobility, health and digital society. For generations, our engineers have proven to be entrepreneurial problem-solvers, both in business and in a social context. At TU Delft we embrace diversity and aim to be as inclusive as possible (see our Code of Conduct). Together, we imagine, invent and create solutions using technology to have a positive impact on a global scale. Challenge. Change. Impact!



The department of Radiation Science & Technology has unique expertise in using ionizing radiation such as positrons and neutrons for research and education. We have direct access to our 2.3 MW nuclear research reactor equipped with  advanced beam-line instruments, irradiation facilities and radiological laboratories, and to the Holland Particle Therapy Center including the proton beam research bunker. Our research focuses on materials science with emphasis on energy conversion and storage, health technology for imaging and diagnostics, radionuclide therapy and proton therapy. Innovative and sustainable nuclear energy is part of our portfolio as well. The department provides education to students in the fields of physics, chemistry and biomedical sciences.  It counts about 20 PI’s, 20 support staff and 70 PhD students and postdocs.
