WDM Permanent MRI System 0.36 T

The i_Open 0.36T system is a medical diagnostic magnetic resonance system. The main magnet of the system adopts the “C” type, single pole structure. The structure has large open degree (the opening angle is larger than 270 degree), which provides the patient much comfort and acceptance. The main magnet has the advantage of compact structure, small size (1.7m×1.1m×1.7m) and light weight (15T) with the static magnetic field strength up to 0.36T

Hardware Description
Magnet
The i_Open 0.36T features an Open C-shape magnet with active shielding. The stability of the magnetic field is ensured via patent design of magnet and a specialized magnet constant temperature system. Magnet constant temperature system is consisted of magnet temperature isolation coat and automatic temperature regulator, which makes magnet working at the stable temperature higher than the magnet room, greatly improved the system stability by cancelling influence from room temperature fluctuation. The magnet’s fringe field is small; the 5-G field is contained within 2.5 m or less in all directions allowing the system to be sited in a small space. The complete system can be installed in a space of 22.5 m2. The excellent magnetic field homogeneity is to ensure superior image quality with a 40 cm field of view.

The open, C-arm magnet design is based on the research and clinical feedback in the area of full body imaging.
The result is a high resolution, wide field of view magnet optimized to image of different part of body scan.

Patient table
The patient table is used for positioning the patient with corresponding RF receiving coils to the iso-center of the magnet for the scanning of MR.
The patient table unit includes two parts: patient table and positioning system. The patient table includes tabletop, tabletop carrier, cushion, etc.
The positioning system includes laser positioning and LED display screen. Two LED screens display the coordinates of the table simultaneously.
When pushing the table frontward, the lower LED will be very convenient to know the exact table position.
o Patient Gap: 39±1 cm
o Support Width: 60 cm
o Max. Patient Weight: 240kg
Gradient System
The i_Open 0.36T gradient system is state-of-the-art, capable of running at 28.5 mT/m with a slew rate of 95 mT/m/ms.
o Maximum Voltage: 150V
o Maximum Current: 150A
More gradient power will support more gradient strength, enable system to provide less slice thickness and smaller minimum FOV, and allows fast (single-shot) TSE sequences with high turbo-factor and
heavy T2-weighting.

Digital RF system
The flat quadrature transmitter coil is integrated in the pole pieces providing a strong uniform field. The 6 kW RF power amplifier allows short pulses to be used,
ensuring the execution of fast imaging sequences available now and those of the future.

Receive platform
The system is equipped with a fully digital two-channel hardware platform.
The technology allows the use of phase array coil. These coils provide image acquisition with higher signal to noise ratio and image quality.

RF Receiving Coils
The i_Open 0.36T RF coils provide excellent signal to noise ratio, due to presence of pre-amplifiers in all elements of the coils and other receiver coils, ensuring proper enhancement of the signal. The i_Open
0.36T comes with a comprehensive set of RF receive coils supporting a wide range of clinical applications from head to toe. Dedicated preset procedures are available for all coils.
