Sequence optimization and appropriate sequence selection is still an unmet need in magnetic resonance fingerprinting (MRF). The main challenge in MRF sequence design is the lack of an appropriate measure of the sequence's encoding capability. To find such a measure, three different candidates for judging the encoding capability have been investigated: local and global dot-product-based measures judging...
In this paper, the principles of uniform circular array (UCA) adaptive beamforming (ABF) based on narrowband radio-frequency signals are introduced. A UCA is composed of a number of uniformly distributed identical half-wavelength dipoles. The least mean squares (LMS) algorithm is applied to antenna beamforming in UCA. It is a method that exploits the array correlation matrix and uses previous samples...
