How to use Technologies offered

A search for a cancer, preclinical stage, synthetic opportunity would use the selection "Therapeutics, Diagnostics" in 'Sector', 'Cancerous, neoplasmatic' in 'Disease Category', 'Drugs, Small Molecule' in 'Technology' and 'Preclinical' in 'Development Stage'.

Selection of 'Enabling Technology, Platform Technology' in 'Sector' will identify all kinds of research technologies that can be used in more areas of life sciences than pharmaceuticals only.

Each technology profile gives the name of a company or academic institute as source of the offer, and a link allowing to contact the potential licensor. In most cases a profile includes a pdf covering the available non-confidential information as well as detailed contact data.

Registered users can create non-public notifications profiles which will inform them about new 'Technologies Offered' entries fitting their needs as specified. In addition these profiles allow them to filter the available information more comfortably.


Antenna assembly for ultra high field MRI (P-978)

Organization name

DKFZ Deutsches Krebsforschungszentrum


Key Facts

  • Body Coil for Ultra High Field MRI
  • Travelling Wave Principle
  • Prototype tested successfully


Ultra High Field magnetic resonance imaging with conventional resonating coils poses disadvantages and patient risks associated with insufficient and inhomogeneous excitation, high global SAR and hot spots. The well known travelling wave excitation with patch antennas uses the main magnet bore as a waveguide. Despite their low efficiency due to the one-pass concept these designs cause high energy deposition in the area of head and shoulders or at the lower extremities, depending on the respective wave entry point.


The DKFZ inventor designed an antenna assembly for ultra high field MRI. This design is characterized by a novel multi-pass travelling wave concept which concentrates the excitation energy to the volume to be examined using well known principles to generate a homogeneous excitation profile with increased efficiency.

Development Stage

The principle was simulated and the coil realized as a prototype and has been tested successfully in pilot studies.

Applications and Commercial Opportunity

The technology can be used for developing and distribution of a new generation of travelling wave coils. The technology provides a solution to the hotspot problem of MRT at high fields.


  • Travelling wave, therefore no standing wave phenomena
  • Multi-pass coil for increased efficiency
  • Easily combined with receive arrays


The invention was conceived by Dr. Reiner Umathum, Department of Medicinal Physics in Radiology (DKFZ, E020).

Intellectual Property

A patent application EP 11 165 140.2 “Antenna assembly for ultra-high field MRI” has been filed May 6, 2011 at the European Patent Office (EPA).
