Oasis vertical field MRI with Zenith RF Technology places the transverse plane of precession in the coronal plane of the patient. This enables a coil element placed in the axial plane to totally enclose the anatomy detecting more of the available signal compared to surface coils in a horizontal field. The result – maximum signal capture even from the center of the patient with high uniformity.
Zenith benefits include:
- Greater SNR efficiency
- Higher sensitivity at the center of the coil – not just the surface
- Higher signal uniformity
Only Oasis delivers the full spectrum of whole body imaging capabilities in an open MRI platform. The patient centric design in combination with our leadership in imaging techniques such as fat suppression, non-contrast MRA, and motion compensation capabilities ensure diagnostic confidence and a pleasant patient experience.
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.
