High frequency research

Our interdisciplinary group of physicians, physicists and engineers works on preclinical characterization and optimization of high frequency electromagnetic fields for therapeutical use. The results of preclinical-biological research together with planning calculations and modeling promote improvement of applications and development of novel high frequency-based therapeutic devices and facilitate and accompany their clinical implementation. The group is also responsible for optimal application, continuous service and quality assurance of the clinical devices.

Interdisciplinary high frequency research group

Our group works on high frequency modeling (power density- and temperature distributions, patient models from imaging data sets), phantom construction, quality assurance and development of hard- and software for planning and optimization of high frequency-based treatments in oncology. One focus is the development of technical solutions for translational research.

The group is associated with the department of radiation oncology and the Charité hyperthermia center. Cooperation partners include the Physikalisch-Technische Bundesanstalt (PTB), the Max Delbrück Center for Molecular Medicine (MDC) and various institutions and clinical departments at Charité.

Methods, algorithms, devices:

  • FDTD-Solver (finite-difference time-domain method) to calculate high frequency electromagnetic fields
  • Time independent BHTE-Solver (bio-heat transfer equation) to calculate non-linear temperature profiles generated by high frequency electromagnetic fields
  • Sim4Life-platform to simulate electromagnetic fields, temperature distributions and to design novel applicators  
  • Eclipse registering and contouring platform (CT, MR, PET-CT)
  • I-Plan for contouring/registration/fusion of image datasets
  • MatLab-based algorithms to convert contours into voxel models
