Jan J W Lagendijk,Bas W. Raaymakers,Alexander J.E. Raaijmakers,J. Overweg,K.J. Brown,Ellen M. Kerkhof,Richard W. van der Put,Björn Hårdemark,Marco van Vulpen,Uulke A. van der Heide +9 more
TL;DR: A prototype hybrid MRI/linac for on-line MRI guidance of radiotherapy (MRIgRT) is under construction, to deliver the radiation dose with mm precision based on diagnostic quality MR images.
Journal ArticleDOI
Design of a radiative surface coil array element at 7 T: the single-side adapted dipole antenna.
Alexander J.E. Raaijmakers,Özlem Ipek,Dennis W. J. Klomp,Cecilia Possanzini,Paul R. Harvey,J J W Lagendijk,C.A.T. Van den Berg +6 more
TL;DR: This work presents a novel design approach, regarding coil array elements as antennas, which is characterized by comparison with three other, more conventional designs using finite difference time domain (FDTD) simulations and B +1 measurements on a phantom.
Journal ArticleDOI
The fractionated dipole antenna: A new antenna for body imaging at 7 Tesla.
Alexander J.E. Raaijmakers,Michel Italiaander,Ingmar J. Voogt,Peter R. Luijten,Johannes M. Hoogduin,Dennis W. J. Klomp,Cornelis A. T. van den Berg +6 more
TL;DR: A fractionated dipole antenna is presented: a dipole where the legs are split into segments that are interconnected by capacitors or inductors.
Journal ArticleDOI
Enhancement of Magnetic Resonance Imaging with Metasurfaces
Alexey P. Slobozhanyuk,Alexey P. Slobozhanyuk,Alexander N. Poddubny,Alexander N. Poddubny,Alexander J.E. Raaijmakers,Cornelis A. T. van den Berg,A. V. Kozachenko,Irina A. Dubrovina,Irina V. Melchakova,Yuri S. Kivshar,Yuri S. Kivshar,Pavel A. Belov +11 more
TL;DR: In this article, the unique properties of ultrathin metasurface resonators can improve magnetic resonance imaging dramatically, and they were shown to improve image resolution by means of subwavelength manipulation with the surface, also allowing improved image resolution.
Journal ArticleDOI
A 16-channel combined loop-dipole transceiver array for 7 Tesla body MRI
TL;DR: To develop a 16‐channel transceive body imaging array at 7.0 T with improved transmit, receive, and specific absorption rate (SAR) performance by combining both loop and dipole elements and using their respective and complementary near and far field characteristics.
