Objectives:
The “MR physics and acquisition methodology group” at the DRCMR carries out research and development aimed at improving MR scanning, e.g. with respect to speed, sensitivity or specificity. The employed methods range from fundamental physics to advanced data processing techniques needed to extract important physiological parameters from the measurements. The targets of the development include imaging, spectroscopy, and multi-modal acquisition such as combined EEG and fMRI. The group also provides education in MRI physics and techniques at the DRCMR, the DTU and elsewhere. Educational material and software developed for this was made freely available, and is now used widely internationally. Group description:
The group members have technical backgrounds, e.g. in physics, mathematics and engineering. Strong external collaborations are established. Most notably, there are strong ties to departments at the Technical University of Denmark (DTU) via Kristoffer H. Madsen and Arnold Skimminge (DTU Informatics) and via double-appointment of Lars G. Hanson (DRCMR and Biomedical Engineering/Medicine&Technology at DTU Electro). Most group members are also associated with other DRCMR groups, focusing more on the applications which provide the ultimate incentives for doing methodological development. Resources:
Data acquisition is done with MR scanners, EEG, ECG and other physiological monitoring equipment. The DRCMR has a well-equipped electronics workshop.
