Petra Kok is responsible for developing the clinical hyperthermia treatment planning at Amsterdam UMC. Her research on hyperthermia has resulted in a research line focusing on clinical hyperthermia treatment planning using on-line adaptive strategies. Furthermore, she explores biological modelling to predict the hyperthermic radiosensitization in terms of effective enhanced radiation dose. Her multidisciplinary research also aims to improve the quality of hyperthermia treatment planning by including patient-specific dielectric tissue properties reconstructed using MR techniques and using advanced thermal modelling techniques including discrete vasculature. Aim of this effort is gaining optimal treatment quality and synergy with radiotherapy and chemotherapy both in terms of tumor temperatures achieved, as well as optimal clinical sequence and time interval with other modalities.

The impact of her research is enhanced by ongoing translation of the developed planning modules into a commercially available clinical hyperthermia treatment planning package for use by clinical hyperthermia professionals worldwide.
