The Ultimate Patient MRI - Open
OASIS is the most powerful patient-friendly whole body high field open MRI system. The unique two pillar asymmetric gantry design provides the best patient experience in terms of MRI comfort. The vertical field magnet with iron core technology in combination with the newest gradient and RF technology guarantees unmatched image quality throughout all applications.
Easy-to-use operating system and extremely fast image reconstruction engine ensures you a high patient throughput in the current highly demanding clinical environment. The unique open architecture not only meets the current requirements of patients regarding comfort, but also gives access to patients previously not suitable for conventional MRI scans.
The solenoid receiver coil of the vertical magnetic field system allows high sensitivity imaging of the important center area. The receiver coil for vertical magnetic field which Hitachi has developed originally makes it possible that the sensitivity is high at the center area which is important within a clinical image.
Also, the sensitivity uniformity is good enough and the diameter can be made smaller for fitting better to the examinee with expectation for further sensitivity improvement.
The receiver coil of the vertical magnetic field system features its high sensitivity as compared with the horizontal magnetic field system. Particularly, high sensitivity at the center area which is important in clinical images allows providing images with a good S/N ratio.
The solenoid receiver coil has high uniformity and the halation in the neighborhood of the coil which is frequent with the multi-array receiver coil of the horizontal magnetic field system is diminished. As signals of fat tissues on the body surface are hard to be strong, it is especially advantageous to fat suppression.
Hitachi's parallel imaging technology ‘RAPID’ is incorporated. Since the RAPID coil based on the solenoid receiver coil has high sensitivity and a high degree of freedom in the imaging direction, imaging time is shortened effectively.
