Summary

Magnetic resonance imaging (MRI) is a non-invasive imaging modality used in routine clinical practice for clinical diagnosis by visualizing the anatomical structure and in vivo function of certain organs. The development of ultra-high field MRI systems with 7.0-T or higher, gives access to a new field of exploration of the human body by improving the speed of acquisition but also a better signal-to-noise ratio (SNR) and better resolution. In order to fully exploit the potential of these ultra-high field MRI scanners, various technical issues must be adressed. Indeed, the non-uniformity of the transmission field is one of them leading to non-uniform images with spatially varying contrast. Thus the pTX (parallel transmission) mode using multiple transmission channels allows spatial and temporal control over the RF waves.
