Division of Image Processing

General Information

The Division of Image Processing, in Dutch abbreviated as the LKEB (Laboratorium voor Klinische en Experimentele Beeldverwerking), is a research group within the Department of Radiology, LUMC. The director of LKEB is Prof. Boudewijn P.F. Lelieveldt PhD.

The goal of our group in a broad sense is the research, implementation and validation of innovative image processing approaches, which allow the objective and reproducible assessment of bio-medical images.

Our research constitutes method development as well as research focused on a particular medical application. We have interest in the complete range of biomedical problems, but have worked particularly on chest CT, cardiac MRI, the vasculature (coronaries, carotids, aorta, etc) imaged by IVUS, OCT or CTA, brain MRI, abdominal imaging (CT and MRI), and more recently also genetic data.

We particularly aim to impact the healthcare system by bringing our research results close to the clinic. To this end we often take an additional step, focusing on high quality implementations that can easily be used by medical doctors. Our scientific programmers therefore work through a formalized Software Development Process (SDP), often in close collaboration with industry, in particular with Medis medical imaging systems BV. This has led to a number of commercially successful products, a.o. QAngio® XA, QMass® MR and QMass® CT. License agreements exist with a number of large medical imaging vendors. The open source image registration software elastix is also maintained at LKEB.
