Overview

hitachi logo

AIRIS Elite continues the tradition of Hitachi’s leadership in Open MR technology, providing clinical capabilities that rival the performance of many high field systems.

This breakthrough results from AIRIS Elite’s Scalable DualQuadTM RF system, higher-order active shim technology, high homogeneity vertical field permanent magnet, super-fast gradients, and sophisticated sequence capabilities, which are all integrated through Hitachi’s unique approach to overall system performance.

These units are to be sold installed as turn-key projects.

  • AIRIS Elite’s permanent magnet design incorporates an asymmetric two-post architecture, Hitachi’s signature design, for maximum openness. Combined with Hitachi’s higher-order active shim technology, the magnet produces a spherical imaging volume of remarkably high homogeneity.
    • Permanent magnet type
    • Vertical magnetic field
    • 0.3T field strength
    • Homogeneity: 0.4ppm@20cm DSV (FWHM)
    Shielding
    • Self-shielded
    • Passive
    Shimming
    • Computer-aided passive shim
    • Gradient shim
    • Active shim (4 channels plus B0 compensation)
    5G fringe field
    • 6.6 ft (horz.) x 8.2 ft (vert.)

Magnet

The Oasis vertical field magnet is 5th generation Hitachi technology providing 1.2T with an open architecture. The magnet features high uniformity complemented by High Order Active Shimming Technology (HOAST) applied per patient.

  • 1.2 Tesla Hitachi vertical field superconducting
  • 45 x 45 x 45 cm FOV
  • Guaranteed Homogeneity
    • 0.3ppm @35cm DSV (Vrms)
  • Active magnetic shielding
  • Helium cryogen
  • Refill: Up to two years

RF System

The Zenith RF receiver system provides the SNR advantage of vertical field magnet technology used in concert with solenoid RF coils. Virtually all of Oasis’ coils support RAPID™ parallel imaging for maximum clinical flexibility and image quality.

  • Zenith 18kW RF Transmit
  • Digital Receiver
    • 8 independent channels
    • 2 coil connection points
    • T/R body coil
    • Zenith RF coils and dedicated anatomy coils

Gradient System

The standard Oasis gradients deliver the capability for rapid acquisition of high-resolution images. The high peak strength and fast slew rate allow the user to select short TE times, small FOV, thin slices and high matrices.

  • Peak amplitude: 33 mT/m
  • Peak slew rate: 100 T/m/s
  • Active shielding
  • Water cooling
  • Gradient noise reduction
    • Softsound™ sequences
    • Sound dampening

Siting

The Oasis design attributes make it accommodating to existing facilities and easily planned into new construction.

  • 5 gauss line
    • Axial 4.0 m (13′ 1″)
    • Radial 3.3 m (10′ 9″)
  • Scan room size
    • 23’ 8” x 16’ 6” (Typical)
