MPT Ingenia 1.5T Omega / OmegaHP: Room Requirements and Technical Specifications

This document provides users and contractors with the essential technical requirements for selecting a room and assessing the feasibility of installing the MPT Ingenia 1.5T Omega / OmegaHP equipment.

Room Selection Criteria

Key considerations for room selection include:

• A separate power supply line from the transformer (TP / TRS).
• Proximity to elevators, electrical rooms, roadways, and metro lines should be considered.
• Floor load-bearing capacity must be verified, with limitations on the amount of metal in the floor.
• Areas with magnetic field strength of 0.5 mT and above, extending beyond the procedure room, must be accounted for.
• The total power requirement for the facility is determined by the UPS system, potentially requiring a higher UPS capacity due to peak currents.
• The route for the quench pipe and helium exhaust system must be considered.

Recommended Room Dimensions and Components

Recommended Dimensions:

• Procedure Room: 7000 x 4800 mm
• Operator Room: 3000 x 4800 mm
• Technical Room: 3000 x 5100 mm
• Recommended ceiling height: 3000 mm (from floor to ceiling slab)

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

Equipment Layout and Specifications

The following diagrams illustrate a typical equipment configuration and serve as a general guide for design. Site conditions, customer preferences, and equipment configuration may influence room geometry and layout. It is recommended to request specific site drawings from a Philips representative during the early stages of design.

Additional Recommendations and Comments

1. The MPT procedure room should not be adjacent (horizontally or vertically) to wards for pregnant women, children, or cardiac patients, nor to rooms for overnight patient stays (according to SP 2.1.2678-20). People with pacemakers are also not permitted in areas with magnetic field strength of 0.5 mT or higher. The height of the tomograph's isocenter is 1.004 m.
2. It is not recommended to install the tomograph beneath rooms from which water leakage through ceilings is possible.
3. Avoid placing significant masses of metal, transformers, high-power electrical equipment, elevators, and electrical cables near the MPT 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 page 3 for verification.
4. Communications under the floor of the rooms, and between walls and the Faraday cage, are highly undesirable. Besides affecting the equipment's operation, access to them after installation will be impossible.
5. It is not recommended to locate the MRI suite in areas affected by communications (elevators, power lines, tram lines, metro lines, etc.). In such cases, assess the risk of magnetic field impact by a certified organization or the equipment manufacturer.
6. A helium emergency exhaust pipe exits through the wall to the outside. Under normal conditions, a minimal amount of gaseous helium is released through it. However, in an emergency, a large amount of helium at very low temperatures is released in a short period. Therefore, it is necessary to fence off an area within a 3 m radius of the pipe outlet, restrict access for people, and prohibit the placement of equipment requiring maintenance, opening windows, and air intake systems.
7. Consider the MRI transport path. Typically, a temporary transport opening in the procedure room wall measuring 2.5 m x 2.5 m (W x H) is made for equipment transport.
8. A temporary unloading area measuring 3 m x 3 m, located above the procedure room level, must be provided. The threshold height between the unloading area and the procedure room depends on the thickness of the Faraday cage floor.
9. The total mass of the Faraday cage is approximately 5-7 tons, with distributed weight.

Heating, Ventilation, and Air Conditioning

Philips provides a climate control system for the equipment's operation, ensuring the required air exchange and microclimate only in the MPT procedure room and technical room. A space of approximately 3.3 m x 1.6 m x 1.8 m (W x D x H), weighing ~1000 kg, must be reserved for the installation of the external climate system unit (chiller). It is recommended to install the chiller unit 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 suite (e.g., operator 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

1. Power supply scheme: Star, 5-wire, TN-C-S: 3 phases, neutral, protective conductor.
   • Supply voltage: 380/400 V.
   • Permissible voltage fluctuations: +10% / -10%.
   • Mains frequency: (50±3) Hz.
   • Phase-to-phase resistance of the network: no more than 0.20 Ohm for Ingenia 1.5 Omega and no more than 0.15 Ohm for Ingenia 1.5 OmegaHP (parameter to be checked at the MRI disconnect switch in the technical room before installation).
   • Total power for Omega gradient: 60 kVA, Nominal current - 90 A; and for OmegaHP: 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 control system power: approximately 60 kVA, Nominal current approximately 90 A.
2. Two separate power supplies must be installed (one for the MRI system, the other for the climate control system). For the MRI, power should be supplied from the transformer substation, through the UPS, with a cross-section that ensures maximum power consumption, equipment current, and phase-to-phase network 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 cable ends should be at least 2 m long. Cable routing from below is recommended.
3. The grounding of 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 resistance of the grounding device should not exceed 1.5 Ohm.
4. MRI procedure room lighting is provided by the Faraday cage manufacturer. Lighting in the operator room and technical room should be provided according to current standards. Due to the presence of many communications on the technical room ceiling, wall-mounted lighting is recommended.

Storage and Handling Conditions

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

The 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 locate 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 may be located in a separate room with forced cooling, adjacent to the electrical room. In this scenario, a climate control system will be needed to manage the excess heat from the UPS.

Philips has no additional ventilation requirements for this equipment. Ventilation should be designed according to applicable standards.
