Team Dewey

Noninvasive Imaging Heisenberg Research Group


about us

Charité Prof. Marc Dewey’s research group focuses on radiology, non-invasive cardiovascular imaging as well as general medical imaging – from experimental research and technical developments over clinical studies to outcomes research including cost-effectiveness, meta-analyses and clinical decision support systems.

Our working group receives funding from the German Research Foundation through the Heisenberg Professorship Program. The main scientific vision of Marc Dewey’s Heisenberg Professorship is to span the divide between technical, molecular, and functional aspects of cardiovascular imaging and evidence-based medicine.

We plan to further advance non-invasive cardiovascular imaging in the future by technical developments based on image segmentation, dose optimization, and quantification. For this, the extended collaboration between radiology, cardiology, physics, biology, mathematics and computer science is intended. If you are interested in working with us on these ambitious projects, please do not hesitate to make contact.

Training – Skills, Knowledge

The scientific activities in the Department of Radiology cover a broad spectrum of highly interesting research areas, from basic research and clinical trials to topics ranging from molecular imaging to interventional radiology.

The broad spectrum of special clinical topics at Charité – Universitätsmedizin Berlin provides an excellent basis for solid and comprehensive training programs at the Department of Radiology.

In addition to the regular clinic-internal meetings of the radiology department (case presentations, morbidity & mortality conferences, presentation of scientific projects and results, safety briefings, strategic discussions, etc.), a 45-minute advanced training course for our physicians in continuing education takes place once a week.

The training has been in existence since 2003 and will be offered additionally from September 2013 in the form of a curriculum relevant to specialists, specifically weighted according to radiological sub-areas, with a total of 99 defined topics. The curriculum can thus be completed by assistant doctors during the specialist training period slightly more than twice before the specialist examination is due.

The training is usually conducted by specialists and senior physicians, taking into account their special expertise (note: many of our clinic’s staff are recognized speakers at national and international congresses).

The advanced training has proven its worth for several years and now takes place at all three camps of the Charité.

Our Trainings


The doctoral college of the Charité – Universitätsmedizin Berlin offers students and doctoral students of the Charité an extensive and free offer of student tutorials on basic skills of scientific work and is at the same time a non-binding contact for general questions about doctoral studies.

The tutorials are:

  • conceived and implemented by the student staff of the doctoral college 
  • evaluated by the participants
  • supported by a scientific advisory board

The doctoral school was founded in 2003 by Prof. Dr. Marc Dewey with the aim of continuously improving the situation of doctoral students at the Charité as well as the quality of scientific doctorates.

To this day, our goal is to pass on experiences and advice from doctoral students to other doctoral students, and we consider it a challenge to promote the exchange of knowledge and encounters between these doctoral students.

Cardiac CT Hands-on Course

Cardiac CT Course

There have been dramatic technical advances in computed tomography for imaging of the heart and particularly the coronary arteries. During the course participants will train with 100 cardiac CT cases of invasive angiography correlation. Also, overview lectures on patient preparation and scanning, as well as Image reconstruction and reading will be given.

Participants of our course (maximum enrollment of 20) are becoming familiar with the new options of state-of-the-art cardiac imaging and expand their skills through practical exercises during 5 days on their dedicated workstations.
