Objective:To do the research on the layout and construction preparation for 3.0T high-field nuclear magnetic resonance equipment room, greatly shorten the construction time and save money for hospital by the safe and convenient usage. Methods: According to the specific characteristics of hospital sitting in full consideration of transportation and distribution, ventilation, bearing, electromagnetic interference and so on, we implement gradually, were ready to work in the construction. Results: Computer room location requirements bearing within 10 tons, magnets, center of 3 m in ferromagnetic material to do assessment, and moving around the car and the transformer must be beyond 3G line, required a special transformer and the capacity of more than 150 kVA. Equipment grounding resistance is less than 2 ohms, shielding room of insulation is greater than 1000 ohms. Super tube is higher than 3.8 m above the ground, there be no air conditioning air inlet. Water-cooled machine well ventilated, northern region need to get the winter outdoor antifreeze. Exhaust air change per hour between magnet design of not less than 12 times. Conclusion: Hospital construction for large equipment and ancillary equipment is installed in the process of each link to match reasonably, pay attention to the collaboration between different units and at the same time. Reasonable equipment layout and construction preparation is the guarantee of equipment installation smoothly.
