Berlin-Brandenburg Academy Prize for Lena Maier-Hein

No. 61 | 01/12/2017 | by Ris

Lena Maier-Hein from the German Cancer Research Center (DKFZ) helps physicians get better vision during minimally-invasive surgery. Using novel methods of image analysis, she wants to provide additional image information for surgeons. Thus, they can better differentiate tumors from healthy tissue and execute safer surgical tumor therapies. Maier-Hein now receives the Prize of the Berlin-Brandenburg Academy of Sciences and Humanities, which is donated by the Monika Kutzner Foundation.

Lena Maier-Hein and her co-workers are working at the interface of computer sciences, medicine and medical technology. Their goal is to develop computer-aided assistance systems that will help surgeons plan and execute surgical interventions better. The DKFZ researcher and her team are developing novel image analysis methods that will enable physicians to remove tumor tissue completely during minimally-invasive surgery without injuring healthy organs, blood vessels and nerves.

When performing minimally invasive surgery, surgeons are faced with major challenges: They need to reach a target region precisely without injuring nearby organs. Additionally, they need to differentiate reliably between malignant tissue and healthy tissue and remove tumor tissue completely in order to prevent the tumor from recurring. So far, physicians have used white light to illuminate the target area inside the body. The endoscopic cameras then deliver only poor contrasts and little depth of vision.

Therefore, award-winner Maier-Hein and her team (Sebastian Wirkert, Thomas Kirchner, Anant Vemuri, Janek Gröhl) have combined standard endoscopic imaging with a technology called multispectral optical and photoacoustic imaging in order to provide additional information for physicians.

Using their new image analysis methods that are based on machine learning, the scientists reconstruct important characteristics of the tissues under examination directly during surgery. “This enables us to assess not only the three-dimensional surface of tissues, but additionally to visualize the details that are hidden beneath, such as the structure of blood vessels, blood supply and oxygen saturation in the target region,” Maier-Hein explains. “These are important clues for physicians about potential malignant tissue alterations.”

During surgery, the surgeon has images of the organ and tissue surfaces plus the additional information provided by the imaging technology. The individual patient’s anatomy, which is calculated based on prior CT and MRI scans, can also be superimposed in 3D on these images.

In collaboration with Heidelberg University Hospital, the innovative methods are being evaluated in computer-assisted endoscopic examinations of the bowel and stomach. Any enhancement in these commonly performed surgical procedures would benefit many people. For this research, Maier-Hein now receives the Academy Prize, which will be presented during the annual festive session at the Academy’s Einstein Day celebration on December 1, 2017.

Lena Maier-Hein, born in 1980, studied computer sciences at the Karlsruhe Institute of Technology (KIT) and at the Imperial College in London and attained her qualification to give lectures (‘Habilitation’) at Heidelberg University in 2013. Since 2009, she has been pursuing research at the DKFZ, where she has been leading an independent junior research group since 2012 and, since fall 2016, the Division of Computer-Assisted Medical Interventions. Maier-Hein has already been distinguished with several science awards including the 2013 Heinz Maier Leibniz Award of the German Research Foundation (DFG) and the 2016 Dr. Emil Salzer Prize. In 2015, she received a Starting Independent Researcher Grant from the European Research Council (ERC).

The Prize of the Berlin-Brandenburg Academy of Sciences and Humanities has been awarded annually since 1998 and is sponsored by the Monika Kutzner Foundation. The prize honors young researchers who have made outstanding achievements in cancer research. It comprises €10,000.

Note on use of images related to press releases
Use is free of charge. The German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) permits one-time use in the context of reporting about the topic covered in the press release. Images have to be cited as follows: “Source: Tobias Schwerdt, DKFZ”.
Distribution of images to third parties is not permitted unless prior consent has been obtained from DKFZ’s Press Office (phone: ++49-(0)6221 42 2854, E-mail: presse@dkfz.de). Any commercial use is prohibited.

The German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) with its more than 3,000 employees is the largest biomedical research institution in Germany. More than 1,300 scientists at the DKFZ investigate how cancer develops, identify cancer risk factors and search for new strategies to prevent people from developing cancer. They are developing new methods to diagnose tumors more precisely and treat cancer patients more successfully. The DKFZ's Cancer Information Service (KID) provides patients, interested citizens and experts with individual answers to all questions on cancer.

Jointly with partners from the university hospitals, the DKFZ operates the National Center for Tumor Diseases (NCT) in Heidelberg and Dresden, and the Hopp Children's Tumour Center KiTZ in Heidelberg. In the German Consortium for Translational Cancer Research (DKTK), one of the six German Centers for Health Research, the DKFZ maintains translational centers at seven university partner locations. NCT and DKTK sites combine excellent university medicine with the high-profile research of the DKFZ. They contribute to the endeavor of transferring promising approaches from cancer research to the clinic and thus improving the chances of cancer patients.

The DKFZ is 90 percent financed by the Federal Ministry of Education and Research and 10 percent by the state of Baden-Württemberg. The DKFZ is a member of the Helmholtz Association of German Research Centers.
