0.5T Open Permanent Magnet MRI System
The 0.5T Open Permanent Magnet MRI System is designed for hospitals and diagnostic imaging facilities that require the accessibility of an open MRI platform together with a higher permanent-magnet field strength.
The system combines a 0.5 Tesla Nd-Fe-B permanent magnet with automatic constant-temperature control, a dual-column open architecture, 25 mT/m gradient strength, 4-channel fully digital RF acquisition, phase-array receiving coils and a Windows-based MRI workstation.
Its open geometry provides a 40 cm vertical gap and wide patient access, while high-accuracy positioning, DICOM 3.0 connectivity and a comprehensive MRI sequence package support routine neurological, musculoskeletal, spinal and selected body imaging workflows.

System Highlights
0.5T Permanent Magnet
The system uses a 0.5 Tesla Nd-Fe-B permanent magnet with automatic constant-temperature control for stable magnetic-field operation.
Open Dual-Column Architecture
The rear dual-column structure provides a 40 cm vertical opening and wide horizontal accessibility, creating a more open examination environment than a conventional cylindrical MRI bore.
≤2.5 ppm Field Homogeneity
Magnetic-field homogeneity is specified at ≤2.5 ppm over a 40 cm DSV using VRMS measurement.
25 mT/m Gradient Strength
The air-cooled gradient system provides 25 mT/m single-axis gradient strength with a slew rate of 75 mT/m/ms.
4-Channel Digital RF
A fully digital transmit-and-receive RF architecture works with phase-array receiving coils for multi-channel MRI signal acquisition.
Advanced MRI Imaging Functions
The supplied software supports routine and advanced functions including FSE, STIR, FLAIR, DWI, TOF MRA, MRCP, MRU and MRM.
Open Dual-Column Design for Patient Access
The magnet uses a rear-positioned dual-column architecture designed to keep the examination area visually and physically open. Compared with a conventional cylindrical bore design, the patient has greater surrounding space and improved accessibility during positioning.
Open Examination Environment
The 40 cm vertical magnet gap and wide horizontal opening provide a less enclosed examination environment, which can be useful for patients who are uncomfortable in narrow MRI spaces.
Front and Rear Accessibility
The dual-column layout leaves the examination area more accessible from the front and rear, supporting flexible patient positioning and operator access.
Positioning Flexibility
The open structure works together with the high-accuracy patient positioning system to support examination of anatomical regions that can be more difficult to position, including shoulder and musculoskeletal applications.
0.5T Permanent Magnet System
The magnet subsystem uses Nd-Fe-B permanent-magnet technology with automatic constant-temperature regulation. Active, passive and dynamic shimming are used to support magnetic-field uniformity during MRI acquisition.
| Magnet Type | Permanent Nd-Fe-B Magnet with Automatic Constant-Temperature Control |
|---|---|
| Field Strength | 0.5T |
| Magnet Structure | Dual-Column Open Structure |
| Field Homogeneity | ≤2.5 ppm, 40 cm DSV, VRMS |

Gradient System
The gradient subsystem provides the spatial encoding required for MRI slice selection and image acquisition. The 0.5T platform combines 25 mT/m gradient strength with a 75 mT/m/ms slew rate and an air-cooled architecture.
25 mT/m Gradient Strength
The specified single-axis gradient strength is 25 mT/m for routine and advanced MRI acquisition.
75 mT/m/ms Slew Rate
The gradient switching specification supports faster spatial encoding and multiple fast MRI sequence technologies.
Dynamic High-Order Shimming
High-order shimming can be adjusted across the X, Y and Z axes to compensate for magnetic-field variations during different examination conditions.
Air-Cooled Gradient System
The gradient coils and power electronics use air cooling, reducing the need for a dedicated gradient water-cooling circuit.
| Gradient Strength | 25 mT/m, Single Axis |
|---|---|
| Gradient Slew Rate | 75 mT/m/ms, Single Axis |
| Rise Time | 0.3 ms |

Typical Clinical Applications
The 0.5T MRI platform supports routine magnetic resonance examinations across multiple anatomical regions. Final examination capability depends on the selected receiving coils, software configuration and local clinical protocols.
Neurological Imaging
MRI sequences including SE, FSE, FLAIR and DWI support routine brain and neurological imaging workflows.
Spine Imaging
The system can be configured for cervical, thoracic and lumbar spine examinations using the appropriate coil and scanning protocol.
Musculoskeletal and Joint Imaging
Dedicated receiving coils and open patient access support examinations of the knee and other selected joints and musculoskeletal structures.
