MAGNETOM OPEN VIVA PREFERRED

he MAGNETOM OPEN VIVA PREFERRED integrates all aspects of the clinical MR exam into an efficient, cost-effective environment. The system has the same computer platform and software as other MAGNETOM systems, which allows the OPEN to quickly take advantage of the latest state-of-the-art imaging techniques. The system utilizes a magnet, which is open on 3 sides for easy patient access. Compact design of the entire system allows easy installation in as little as 325 square feet.
C-Shaped Resistive 0.2T Magnet
The MAGNETOM OPEN has an open C-shaped, 0.2 Tesla magnet, magnet power supply, and passive shim system. The wide horizontal opening of the magnet increases patient comfort and allows easy access to the patient. The water-cooled magnet weighs only 12 metric tons In its operational configuration. The 5 gauss line extends 8 feet 6 inches in front of the magnet and only 7 feet 10 inches in all other directions, which in many installations can be constrained within the exam room.

Gradient System

15 mT gradients with a rise time of 900 usec in all three spatial directions are integrated into the magnet design. Siemens uses a proprietary design to achieve flat actively shielded gradient coils, which provide axial, sagittal, coronal, oblique and double oblique cross-sectional Images of the whole body. This powerful gradient system allows easy implementation of new techniques due to its flexibility. Digital RF System A digital RF system, operating at 8.25 MHz, features computer-controlled signal processing to generate arbitrary RF pulse shapes for accurate slice profiles. The maximum power output is 2 kW with high frequency stability.
