Magnetic Resonance Tomograph 0.36T

The 0.36T MRI system is a medical diagnostic magnetic resonance system. The main magnet of the system embodies the “C” shaped design type, single-pole structure. The structure has a greater degree of openness (opening angle greater than 270 degrees), which provides the patient with greater comfort. The main magnet has the advantage of compact design, small size (1.7m x 1.1m x 1.7m) and light weight (15T) with a static magnetic field strength of up to 0.36 Tesla.

Magnet
The MRI 0.36T has an open C-shaped magnet with active protection. The stability of the magnetic field is ensured using a patented magnet design and a specialized system for maintaining a constant magnet temperature.
The constant temperature magnetic system is composed of an insulating layer of magnetic insulation and an automatic temperature controller, which keeps the magnet temperature stable higher than the room temperature, which greatly improves the stability of the system by canceling the influence of room temperature fluctuations.
The fluctuation of the magnet field is small; The 5-G field is kept within 2.5 m or less in all directions, allowing the system to be installed in a small space. The complete system can be installed in a space of 22.5 m2.
Excellent magnetic field uniformity ensures excellent image quality with a 40cm field of view.
The open C-arm magnet design is based on a research and clinical foundation in full body imaging. The result is a high-resolution, wide-field magnet optimized for imaging different parts of the body.

Patient table
A patient table is used to position the patient with appropriate RF receiving coils to the isocenter of the magnet for MR scanning.
The patient unit consists of two parts: the patient table and the positioning system. The patient table includes a table deck, deck carrier, cushions, etc.
The positioning system includes laser positioning and LED screen. Two LED screens display table coordinates simultaneously.
• Table width: 60 cm
• Table height: 76 cm from the floor
• Max. patient weight: 240 kg

Gradient system
The 0.36T MRI gradient system is state-of-the-art, capable of operating at 28.5 mT/ms with a slew rate of 95 mT/m/ms.
• Maximum voltage: 150 V
• Maximum current: 150 A
Higher gradient power maintains greater gradient strength, allowing the system to provide thinner slice thicknesses and smaller field of view minimums, and allows rapid (one-shot) acquisition of a highly compressed TSE sequence.

Digital RF System
A flat quadrature transmitting coil is built into the pole pieces, providing a strong, uniform field. The 6 kW RF power amplifier allows the use of short pulses, enabling fast image sequences.

Reception platform
The system is equipped with a fully digital two-channel hardware platform. This technology allows the use of phased array. These coils provide higher signal-to-noise ratio and better image quality.
The RF receiving system adapts quantum optical fiber transmission technology. Analog/digital conversion and quantum laser modulation are placed inside the magnetic room, which helps to significantly reduce signal loss and prevent interference during transmission. As a result, the image quality is effectively improved.

RF Receiver Coils
MRI 0.36T RF coils provide excellent signal to noise ratio due to the presence of preamplifiers in all coil elements and other receiver coils, ensuring proper signal amplification. The 0.36T MRI comes with a complete set of RF receiver coils to support a wide range of clinical applications from head to toe. Dedicated preset routines are available for all coils.
