As a PhD student you will work on improving and developing methods for image-guided, adaptive radiotherapy treatment of oesophageal cancer. Radiotherapy is a treatment modality where patients receive a high radiation dose localized to the tumour, while minimizing exposure of surrounding normal tissue. Exact delineation of the tumour on medical images forms the basis for an accurate treatment. Daily imaging of the patients prior to irradiation allows adjustment of the treatment to enhance accuracy further.

Radiotherapy of oesophageal cancer is particularly challenging. Target definition on medical images suffers from inter-observer variability and motion of the oesophagus further increases the uncertainty in localizing the target at the time of treatment.

In this project you will use machine learning techniques to develop automatic delineation of the target. With a large data set of images taken before and during treatment, you will develop and demonstrate image-guidance and adaptive treatment strategies to improve the accuracy of treatment delivery.


You have obtained a MSc degree in physics, biomedical engineering, technical medicine or a related discipline. In addition, you are interested in image analysis, image registration and radiotherapy: experience in these fields is appreciated. You are highly motivated, and able to work independently as well as in a multidisciplinary team. You should be able to communicate effectively across different disciplines.


You will be employed on the basis of a 36-hour week. Appointment should lead to a PhD thesis and is for a maximum duration of four years. Your salary is € 2,279 gross per month in the first year, progressing to € 2,919 gross per month in the fourth year based on a full time position (scale PhD students of the Collective Labor Agreement for University Hospitals).

The terms of employment offered by the LUMC are highly favorable. For example, you will receive 8% holiday remuneration, a year-end bonus, and a pension arrangement with the National Civil Pension Fund. Also, as employee of one of the University Hospitals in the Netherlands, you can benefit from our collective health insurance policy.

Moreover, the LUMC offers excellent facilities in the area of education, child-care center, and career advice.
