Hitachi Oasis 1.2T MRI

The Hitachi Oasis 1.2T is known as the strongest high-field Open MRI scanner.
This scanner focuses on comfort, with true patient-centric design.
With Oasis, you can scan patients with special needs in no time.
Its open gantry creates a spacious feeling, with an unobstructed view
and access from all sides;
while calming ambient lighting and silent scanning help your patient relax even more.
Children who need a hand to hold, claustrophobic and anxious patients,
obese or very muscular patients, and patients who need interventional procedures
will have the space they need to feel comfortable and at ease for smooth scanning.

Open gantry designed for claustrophobic, bariatric, geriatric and pediatric patients or interventional scans.
Extra-wide patient table handles up to 300kg, with in-gantry left & right movement and multiple coil connectors.
QuickScan accelerates the exam process for anxious or motion-prone patients.
Efficient workflow enables greater productivity - from patient registration
to positioning, scanning and post-processing.
Advanced magnet technologies and imaging features deliver outstanding image quality.

Comfort:
OASIS delivers an open design of a 270° round view with a spacious feeling.
Quick scans and quiet noise levels add to a relaxed, positive patient experience.

Open architecture with a vertical magnet and two pillars with a 270° round view.
Industry-leading 82cm-wide patient table includes in-gantry lateral movement,
a 300kg weight capacity, and multiple coil connectors.
Reduce noise levels without prolonging scan time or compromising image quality
with SoftSound.
QuickScan setting accelerates the scanning process so
that your patient spends minimum time on the table.
Scan and diagnose complex vascular systems using a variety
of non-contrast techniques.

Claustrophobic and anxious patients:
Claustrophobic and anxious patients are given the space they need with Oasis..
Thanks to its spacious design, patients can get distracted by what’s going on outside the scanner, stretch out their arms- and breathe.

Obese or very muscular patients:
Obese or very muscular patients can struggle to fit inside a conventional MRI tube.
Oasis provides enough space for them to be comfortable and fit with ease.
It’s provided patient table can hold up to 300kg, enabling you to examine the largest
of patients.

Children:
Ensuring that your patient lays as still as possible during the scan is essential
for obtaining clear images and a more accurate diagnosis.
Children and the elderly can get nervous, fidgety and upset in an MRI tube.
Oasis allows a loved one to sit with the patient for the entire scan - be able to speak
with them and hold their hand to help finish an exam successfully.

Interventional procedures or critical care:
OASIS’ open gantry allows you to conduct real-time interventional procedures -
and observe your needle on a monitor without repositioning the patient.
The patient stays inside the gantry during the whole procedure unlike a tunnel system.
The result: you can perform prostate or breast biopsies, pain therapy
or laser therapy faster, easier and more accurately.

High-field, clinical capabilities:
All around RADAR imaging to reduce motions artifacts.
Various fat suppression methods with minimized influence of magnetic susceptibility,
like STIR, FatSep, H-Sinc or Water Excitation.
Image quantification with T2 RelaxMap showing actual T2 values in a color overlay -
to support orthopedic studies and the depiction of articular cartilage.
Various advanced imaging features, like RAPID, TIGRE, ADAGE, TRAQ, FLUTE, VASC,
BSI and isoFSE.
Individual shimming per patient for a uniform magnetic field,
outstanding image quality and patient comfort with HOSS.

User-friendly and efficient workflow:
Scan faster with our QuickScan setting.
Automatic slice positioning with AutoPose.
Remote application support to help optimize protocols, train technicians -
and control the entire exam online with SENTINEL™.
Remote maintenance support delivers automatic notification of anything suspicious
via SENTINEL™ - maximizing your uptime.
