Hitachi Airis Elite 0.3T

AIRIS Elite 0.3T is a combination of the renowned reliability, cost-effectiveness
and patient comfort of the AIRIS II with throughput
and capabilities previously not seen at Open low-field.
The Elite’s permanent magnet design incorporates
an asymmetric two-post architecture, for maximum openness.
The proven performance of AIRIS Elite’s vertical field permanent magnet
with higher-order active shim technology, Scalable DualQuad RF system,
and broad sequence abilities are all integrated through Hitachi’s unique approach
to optimize system performance.

AIRIS Elite continued the tradition of Hitachi's leadership in Open MR technology,
providing new capabilities to low-field MRI including parallel imaging
and RF fat saturation.

Features:
Higher Order Active Shim enables RF fat saturation at 0.3T
21mT/m and 55T/m/s gradients for high resolution and fast scan time
RAPID parallel imaging for shorter scan times
