Biomedical Magnetic Resonance

Department 8.1

Tasks

The department engages in method development for magnetic resonance imaging (MRI) and spectroscopy (MRS).

Specific methodological aspects of MRI are covered by currently three research groups: physical basics and safety (8.11), data acquisition and image reconstruction algorithms for motion correction and multimodal imaging (8.13), excitation and acquisition techniques specifically designed to harvest the potential of 'ultrahigh' (7T) magnetic fields (8.14).
Central research tool is a whole-body 3-tesla MR scanner. Additionally, the department is engaged in the Berlin Ultrahigh Field Facility which is operating a 7-tesla whole body scanner.

News

The separate imaging of fat and water rich tissue is a frequent objective in magnetic resonance imaging (MRI). An efficient solution is provided by the Dixon technique where both compartments are excited simultaneously and the signals are later separated based on their different temporal evolution. At the 'ultrahigh' MRI field strength of 7T, the frequency shift between fat and water protons is...

Last fall, the research paper "Wirelessly interfacing sensor-equipped implants and MR scanners for improved safety and imaging" by Berk Silemek, Lukas Winter, and colleagues was published in Magnetic Resonance in Medicine (MRM). This article was now chosen as an MRM Highlights Pick "… because they openly shared design files and software for the MRI implant sensor they developed" (see gitlab1.ptb...
