As a PhD candidate at TU Delft, you will develop a new type of radiation detector that opens up new possibilities for the image-guided treatment of cancer.

Job description

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 PhD student 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.

MPT'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.

Your PhD project will be carried out in collaboration 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 young 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) at 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 an MSc in Physics, Applied Physics, or similar discipline. We are looking for candidates with affinity for 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, actively participate in international conferences, and write a PhD thesis. 

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate Schools Admission Requirements.

Conditions of employment

Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills.

The TU Delft offers a customisable compensation package, discounts 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.
