Initial
measurements demonstrate significant gains in SNR and parallel imaging
performance. Further characterisation of the transmit and receive performance
of this setup is planned.
Figure 2: A – Picture of the completed receive array. An input board on the helmet surface
consists of the matching and active detuning circuit. A feed-board with
preamplifier is on a holder above the helmet; B – Picture of the final setup; C – View
from the service end highlighting the visual field.
Figure 1: A – EM simulation setup. Tuning,
matching and decoupling was adjusted by loading the coil with a
head & shoulder phantom; B – A view of the transmit array model is shown to
visualise the arrangement. Channels 1 to 8 are on the top row and 9 to 16 are
on the bottom row, arranged one below the other.
