By irradiating ultrasound (US) into a tissue-mimicking sample, a displacement along the US beam path caused by the acoustic radiation force is obtained. This displacement varies with the US intensity, the duration of irradiation, the US attenuation and the viscoelastic properties of the sample. US pulses of 2.5 MHz with a duration of 20 ms and an intensity of <17 W/cm(2) are used. An MRI sequence was programmed to produce images in which the magnitude of the displacement is visualized by gray value changes. In addition, a finite element simulation of the measurements was performed to demonstrate the feasibility of the method. Through examination of the measurements and the simulations, information about viscoelastic changes was achieved. In this work, measurements on different breast phantoms are presented.}, tags = {mrt}, url = {http://www.sciencedirect.com/science/article/pii/S0301562910006186}, DOI = {10.1016/j.ultrasmedbio.2010.11.005}, author = {Radicke, M. and Mende, J. and Kofahl, A.-L. and Wild, J. and Ulucay, D. and Habenstein, B. and Deimling, M. and Trautner, P. and Weber, B. and Maier, K.} } @Article { paperkalk, title = {Acoustic radiation force contrast in {MRI}: detection of calcifications in tissue-mimicking phantoms}, journal = {Medical Physics}, year = {2010}, volume = {37}, pages = {6347-6356}, tags = {mrt}, url = {http://online.medphys.org/resource/1/mphya6/v37/i12/p6347_s1}, DOI = {10.1118/1.3512806}, author = {Mende, J. and Wild, J. and Ulucay, D. and Radicke, M. and Kofahl, A.-L. and Weber, B. and Krieg, R. and Maier, K.} } @Article { Mende2010203, title = {Nuclear acoustic resonance in fluids using piezoelectric nanoparticles}, journal = {Journal of Magnetic Resonance}, year = {2010}, volume = {203}, number = {2}, pages = {203 - 207}, tags = {mrt}, url = {http://www.sciencedirect.com/science/article/pii/S1090780709003747}, ISSN = {1090-7807}, DOI = {10.1016/j.jmr.2009.12.019}, author = {Mende, J. and Elmiladi, N. and H{\"o}hl, C. and Maier, K.} } @Article { springerlink:10.1007/s10751-008-9628-6, title = {New image contrast method in magnetic resonance imaging via ultrasound}, journal = {Hyperfine Interactions}, year = {2008}, volume = {181}, pages = {21-26}, abstract = {When applied to a sample, ultrasound (US) gives rise to a displacement of tissue and a flow in a liquid due to the acoustic radiation pressure.
