The shortened radio frequency wavelength in high field MRI makes it challenging to create a uniform excitation pattern over a large field of view, or to achieve satisfactory transmission efficiency at a local area. Transmit arrays are one tool that can be used to create a desired excitation pattern. To be effective, it is important to be able to control the current amplitude and phase at the array elements. The control of the current may get complicated by the coil coupling in many applications. Various methods have been proposed to achieve current control, either in the presence of coupling, or by effectively decouple the array elements. These methods are applied in different subsystems in the RF transmission chain: coil; coil-amplifier interface; amplifier, etc. In this review paper, we provide an overview of the various approaches and aspects of transmit current control and decoupling.

2023 has been a year of growth and transformation for IEEE Reviews in Biomedical Engineering (RBME). Thanks to our authors, reviewers, and editorial board members, RBME received strong metrics on Impact Factor and CiteScore reaching 17.6 and 27.8 respectively, which places RBME in the top 3 according to the Impact Factor, and the top 4 according to the CiteScore in all Biomedical Engineering Journals/Publications. We have also observed substantially increasing submissions in the past year. To better serve our authors, we have implemented a screening process to quickly communicate the outcome of assessment, and allow the authors to submit manuscripts which do not fit the scope or have a low chance of passing through the highly selective review process, to find a more suitable journal in a timely manner.
