1. Magnet System

Feature	Specification	Analysis
Type	Superconductive	Gold standard in modern MRI. Superconductive magnets ensure stable and powerful magnetic fields essential for high-quality imaging.
Field Strength	1.5 Tesla	Commonly used clinical strength, offering a balance between image quality and patient safety. Sufficient for neuro, musculoskeletal, abdominal, and cardiovascular imaging.
Shielding	Active	Reduces magnetic fringe fields, minimizing infrastructure costs (e.g., less room shielding required). Enhances safety in nearby environments.
Shimming	Active + Passive + Dynamic	Ensures excellent field homogeneity, leading to clearer images with fewer artifacts. Multiple shimming modes allow adaptation to different imaging situations.
Stability	≤ 0.1 ppm/h	Highly stable — ensures that image quality remains consistent over time.
Homogeneity (DSV/VRMS)	From ≤0.832ppm at 45cm to ≤0.01ppm at 10cm	Very high homogeneity. Ideal for both small region-of-interest scans and whole-body imaging.
Inner Bore	600 mm	Standard patient bore. Comfortable for most patients but not ultra-wide.
Length	157 cm (excluding cover)	Reasonably compact for a superconducting magnet. May allow more flexible room layouts.
5 Gauss Line	≤2.5m x 2.5m x 4.0m	Compact fringe field helps ensure safety zones are manageable — critical for MRI room planning.

2. Gradient System (Performance Controls Inc., USA)

Feature	Specification	Analysis
Max Gradient Field	41 mT/m	Adequate for clinical and advanced imaging sequences (e.g., DWI, fMRI).
Max Slew Rate	187 mT/m/ms	Excellent — enables fast imaging, essential for dynamic studies, cardiac imaging, etc.
Minimum Rise Time	0.22 ms	Fast — supports high temporal resolution imaging.
Simultaneous Max Gradient & Slew	Yes	Indicates well-optimized hardware performance.
Cooling	Water Cooling	Ensures consistent performance and prevents overheating, especially during demanding sequences.
Control System	Full digital real-time	Enhances synchronization and reduces distortion/artifacts. Modern and efficient.

3. RF System (MR Solutions Ltd. & Analogic, USA)

Feature	Specification	Analysis
Spectrometer	All-digital	Modern and reliable, allows precise signal acquisition.
Amplifier Power	18kW	High power ensures deep tissue penetration and high-quality signal-to-noise ratios.
Center Frequency	63.87 MHz	Appropriate for 1.5T field strength — ensures resonance of hydrogen protons.
Digital Monitoring	Real-time monitoring (energy + accumulation, short & long term)	Improves patient safety, system protection, and data fidelity. Reflects an advanced and safety-focused design.
Transmitting Coil	Included	Ensures compatibility and optimized performance. Likely a body or volume coil for transmission.

4. Computer System & Console

Feature	Specification	Analysis
CPU	Dual Core ≥2.8GHz	Decent, but may be slightly outdated by today’s high-end imaging workstations. Can still support clinical operations.
RAM	≥2GB	Low by modern standards. Recommend upgrade to 8GB+ for faster reconstruction and processing.
Display	≥24" LCD TFT	Acceptable; large enough for viewing high-res scans.
Console Software	Bilingual, user-friendly	Promotes accessibility and user efficiency.
Operating System	Windows XP Professional	Outdated — may pose cybersecurity risks. Strongly recommend update to Windows 10 or embedded Linux for stability and support.

5. Monitoring Systems

Feature	Specification	Analysis
Machine & Patient Monitoring	Multi-parameter	Vital for patient safety and clinical use, especially in anesthetized or critical care patients.

✅ Strengths:

Industry-standard 1.5T with excellent homogeneity and stability
High-end gradient and RF specs for diverse clinical use
Fully digital systems with safety-focused monitoring
