Hitachi Oasis 1.2T MRI Features and Specifications:

Magnet
The Oasis vertical field magnet is a 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 the 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)
