MPT Ingenia Ambition 1.5T S/X: Room Requirements and Technical Specifications

Room Selection Criteria

This document provides users and contractors with the essential technical requirements for selecting a room and assessing the feasibility of installing the equipment.

Important Considerations:

• Separate power supply line from the transformer (TP / TRSZ) is required.
• Consider proximity to elevators, electrical rooms, roadways, and the metro.
• Assess floor load-bearing capacity and limitations on metal content in the floor.
• Account for areas with magnetic field leakage of 0.5 mT and above outside the procedure room.
• The total power requirement at the healthcare facility is determined by the UPS system, which may allow for a higher UPS capacity due to peak currents.
• MPT BlueSeal systems do not require a helium emergency exhaust pipe.

Recommended Room Dimensions and Layout

Procedure Room: 7000 x 4800 mm

Operator Room: 3000 x 4800 mm

Technical Room: 3000 x 5100 mm

Recommended Ceiling Height: 3000 mm (floor to ceiling slab)

Rooms with smaller dimensions may present mechanical limitations and operational or maintenance difficulties.

Equipment Layout and Specifications

The diagram below illustrates a typical equipment configuration and serves as a general design guide. Site conditions, customer preferences, and/or equipment configuration may significantly influence room geometry and equipment placement. It is recommended to request specific site drawings from a Philips representative during the early stages of design.

Ferromagnetic Object Placement Check

The diagram below is for checking the placement of ferromagnetic objects within a 3x3 meter area around the MRI isocenter.

General Recommendations and Comments:

• Do not place the MRI procedure room adjacent to rooms for pregnant women, children, or cardiac patients, or rooms for round-the-clock patient stays. People with pacemakers should not be in areas with magnetic field strength of 0.5 mT or higher. The height of the tomograph isocenter is 1.004 m.
• Avoid installing the tomograph below rooms with potential water leakage through floors.
• Do not place significant masses of metal, transformers, high-power electrical equipment, elevators, or electrical cables near the MRI procedure room. Vehicles, trams, etc., moving in close proximity to the MRI suite can also have an undesirable effect. Refer to the diagram and graph on Sheet 3 for checks.
• Communications under the floor or between walls and the Faraday cage are highly undesirable, as they not only affect the equipment's operation but also become inaccessible after installation.
• Avoid locating the MRI suite in areas influenced by communications (elevators, power lines, tram lines, metro lines, etc.). In such cases, assess the risk of magnetic field impact with a certified organization or the manufacturer.
• Provide pathways for MRI equipment transportation. Typically, a temporary transport opening of 2.5 m x 2.5 m (W x H) is made in the procedure room wall for equipment transport.
• Provide a temporary unloading area of 3 m x 3 m above the procedure room level. The threshold height between the unloading area and the procedure room depends on the thickness of the Faraday cage floor.
• The total weight of the Faraday cage is approximately 5-7 tons, distributed weight.

Heating, Ventilation, and Air Conditioning (HVAC)

Philips provides a climate control system that ensures the required air exchange and microclimate only in the MRI procedure room and technical room. A location for the external climate control unit (chiller) of approximately 3.3 m x 1.6 m x 1.8 m (W x D x H) with a weight of ~1000 kg needs to be reserved. The recommended installation area for the chiller is near the technical room, outside the building, or on the roof in agreement with Philips. Additional climate control equipment is not required.

Other rooms within the MRI complex (e.g., control room, preparation room, etc.) are not connected to the climate control system. Air exchange in these rooms should be provided in accordance with applicable regulations.

Power Supply Requirements

• Power supply scheme: Star, 5-wire, TN-C-S: 3 phases, neutral, protective conductor.
• Power supply voltage: 380/400 V.
• Mains frequency: (50±3) Hz.
• Allowable voltage fluctuations: +10% / -10%.
• Mains phase resistance: Ambition S - no more than 0.20 Ohm, and Ambition X - no more than 0.15 Ohm (parameter to be verified before installation at the MRI disconnect switch in the technical room).
• Total power for MPT Ambition S system: 60 kVA, Nominal current - 90 A; for Ambition X system: 80 kVA, Nominal current - 116 A.
• Peak current: 400A (for no more than 5 ms), 500A (for no more than 1 ms); Power factor = 0.9.
• Climate system power: approximately 60 kVA, Nominal current - approximately 90 A.

Two separate power supplies are required (one for the MRI system, one for the climate system).

For the MRI: from the transformer substation, through the UPS, with a cross-section ensuring maximum power consumption, equipment current, and mains phase resistance not exceeding the required level. Only Philips equipment should be connected to this separate line. Power and grounding cables should be routed to the location indicated on the room preparation plan for installation. Free ends of cables should be at least 2 m long. Bottom cable routing is recommended.

The grounding system for the medical device must comply with local legislation and regulatory requirements. The grounding loop should be connected to the main grounding bus of the building. The grounding resistance should not exceed 1.5 Ohm.

Lighting within the MRI procedure room is provided by the Faraday cage manufacturer. Lighting in the control room and technical room should be provided according to current standards. Due to the numerous communications on the technical room ceiling, wall-mounted lighting is recommended.

Storage and Handling Conditions

The equipment is delivered in large crates (approx. 50 units, total weight ~22 tons). A temporary storage area for the equipment must be prepared and agreed upon with the Philips Healthcare project manager, adhering to the storage conditions below. The temporary storage location should be in close proximity to the equipment installation room.

Equipment must be stored in conditions that exclude exposure to atmospheric precipitation, low, and high temperatures.

Uninterruptible Power Supply (UPS)

The UPS is typically supplied in two cabinets. Due to high heat dissipation, it is recommended to place the UPS in the MRI technical room. In this case, the climate control system will dissipate the excess heat from the UPS.

If there is insufficient space in the technical room for the UPS, it can be placed in a separate room with forced cooling, adjacent to the electrical room. In this scenario, a climate control system will need to be planned to dissipate the excess heat from the UPS.

No additional ventilation requirements for this Philips equipment are specified. Ventilation should be designed according to applicable standards.
