PhDs in Medical Imaging
Job description
Positron emission tomography (PET) is a key medical imaging technique in the diagnosis of cancer and many other clinical and research applications. Recently the use of time-of-flight (TOF) information, requiring sub-nanosecond timing resolution, has led to significant improvement in PET image quality.
The SUBLIMA project (www.sublima-pet-mr.eu) is a FP7 Large-scale Integrating Project in which TU Delft is collaborating with Philips Research and several other institutions to realise truly simultaneous, fully integrated, whole-body TOF-PET/MRI technology for concurrent functional and anatomical imaging. It will combine the extremely sensitive functional imaging possibilities of PET with the excellent soft-tissue contrast and complementary functional imaging capabilities of MRI.
SUBLIMA aims to push TOF-PET to the physical limits by introducing new methods and technologies in every part of the imaging chain. At TU Delft we have recently established a world-record coincidence resolving time (CRT) of ~100 picoseconds. Within SUBLIMA we will take this research forward by focusing on a novel, compact, scalable, MR-compatible PET detector concept that makes use of new scintillation materials, new solid-state light sensing technology, and real-time, digital signal processing, which will form the basis for PET systems with unsurpassed imaging performance.
Requirements
For this project we are looking for enthusiastic and creative young physicists who are motivated to push the limits in medical imaging instrumentation in close collaboration with colleagues from the other institutions involved in the project.
Good communication skills and excellent English are requested. Applicants should possess a pro-active, independent, problem-solving, and result-oriented work attitude. Successful candidates will be expected to publish their results in peer-reviewed scientific journals, to participate actively in international conferences, and to write a PhD thesis.

MAASTRO CLINIC has a vacancy for a PhD student in Dose Guided Radiation Therapy with time-resolved 4D portal imaging (M/F).
Job description
In this position you will carryout research in dose guided radiotherapy for various cancer sites, e.g. lung. You will develop a method for obtaining 4D (time-resolved) portal images of a patient during treatment, and use these images to quantify and comprehend changes in patient geometry compared to the planning CT, and other potential causes of divergence. You will also use these images to reconstruct the true received dose during daily treatment fractions and compare this dose to the planned dose. For this you will use the (4D) cone-beam CT images acquired during the treatment. You will help develop protocols for adaptive radiotherapy based on your findings.
Requirements
We are looking for acandidate with a masters degree (or equivalent) in Physics or Engineering. We expect you to have a GPA of at least 3.5/4 for your Masters degree. Experience with image processing is highly valued, and experience with adaptive radiotherapy is a plus. Programming experience and enthusiasm for it is a must. The enthusiastic candidate that we are looking for must be fluent in English. You must provide two letters of reference.
Conditions of employment
Conditions of Employment and salaryare based on the Dutch Collective Labour Agreement for Hospitals (CAO-Ziekenhuizen). You will receive a fulltime contract (36 hours/week) for an initial period of one year, with the intention for extension up to 4 years. Your salary will be according to the scale of scientific researcher 4 of MAASTRO clinic, and is depending on your relevant experience. Furthermore the Collective Labour Agreement offers an extended package of secondary conditions, among others an 8%-holiday bonus, a yearly bonus and excellent pension arrangements and health insurance arrangements.
Contract type
Temporary
one year, with the intention for extension up to 4 years.
Organisation
MAASTRO, Maastricht Radiation Oncology, is a co-operation between MAASTRO clinic, the University of Maastricht (UM) and the University Hospital Maastricht (MUMC+) (see http://www.maastro.nl). MAASTRO consists of several divisions, including MAASTRO clinic, which offers state-of-the-art radiotherapy to more than 3500 cancer patients each year from the mid and South Limburg area in the Netherlands. In addition, research and training at MAASTRO is carried out in MAASTRO Physics, MAASTRO Trials, MAASTRO School, and MAASTRO Lab.
MAASTRO clinic is a radiotherapy treatment and research facility embedded within the GROW research institute of the Faculty of Health, Medicine and Life Sciences at Maastricht University. Research carried out in the past has focused on molecular PET/CT imaging, computer aided theragnostics and dose guided radiotherapy (DGRT). In the latter we have developed techniques to determine the real dose delivered to the patient during radiotherapy, based on portal imaging and cone beam imaging technology. We have successfully introduced this methodology in the clinic. We are now expanding our DGRT research activities by using time-resolved 4D portal imaging.
MAASTRO clinic has seven permanent physicists, several technicians, informaticians, and 13 PhD students/postdocs and is fully equipped with linear accelerators, verification imaging devices, a brachytherapy suite, a PET-CT scanner, a wide bore CT scanner, many treatment planning stations etc. Together with MAASTRO lab we installed a small animal irradiation/imaging facility. MAASTRO collaborates with TU/Eindhoven, University of Toronto, the McGill University of Montreal, the University of Leuven, the Netherlands Cancer Institute, and we host a large international in-silico trial on particle therapy.

The spatial and spectral accuracy of conventional Magnetic Resonance Imaging (MRI) and Spectroscopy (MRS) techniques depends on the uniformity of the main magnetic field and the resonance frequency. Deviations in these values severely restrict the utility of high field MRI.
You will be working on a Ph.D. project that aims at improving MRI in magnetically heterogeneous anatomies such as the inner ear and the nasopharynx as well as in the presence of external devices such as biopsy needles, implants or exogenous magnetically labeled diagnostic substances.
Requirements
You are an enthusiastic, motivated candidate who is interested in an international MRI research project. You will have a M.Sc. in (bio)physics, chemistry, (bio)medical engineering, biomedical image sciences or a comparable field. You will be able to work independently and to contribute to multidisciplinary research within a team. Experience with NMR/MRI is strongly desired and experience with (pulse-)programming is a plus.

PhD position Experimental Physics: Precision dose delivery in protontherapy
The PhD student will develop a method to extract accurate proton stopping powers from dual energy or spectral CT-scans and thereby improve treatment plans in proton therapy.
The X-ray attenuation coefficients measured in CT-scans are influenced by both the electron density and the elemental composition of the tissue, whereas the proton stopping power is essentially determined by the electron stopping power. Currently the proton stopping powers are derived from the CT-scans using a phenomenological relation between the measured attenuation coefficients and proton stopping power. This causes a significant uncertainty in the proton penetration depth, which imposes additional constraints on the treatment planning.
Dual-energy and spectral CT makes it possible to separate the contributions of the electron density and the elemental composition to the attenuation coefficients and thereby to increase the accuracy of the proton stopping powers.
Proton stopping in phantoms with relevant geometries and compositions will be determined from simulations and proton radiography measurements and indirectly from dual energy and/or spectral CT-scans of the phantoms. The comparison of the results obtained via both routes will be used to optimize and validate the method to extract protons stopping powers from the CT-scans. The development of a simple proton radiography system is part of the project.
We are seeking a PhD student Experimental Physics: Precision dose delivery in protontherapy.
