Smart Film Privacy Solutions for MRI Units

Updated: Jun 18

Mobile MRI units—mounted in trucks or trailers—bring advanced diagnostic imaging directly to patients, especially in remote or underserved areas. These units replicate the capabilities of fixed-site MRIs, but are engineered for mobility and rapid deployment. Their interior design includes RF and magnetic shielding to maintain image quality and patient safety, with integrated climate control and power systems—a feat of precise engineering.

Given their public and temporary settings, mobile MRI units pose unique privacy challenges. Patients often undergo disrobing and confined procedures inside a compact, glass-lined space. Ensuring confidentiality and comfort during these moments is critical, making smart glass solutions increasingly relevant. PDLC smart film and smart glass deliver instant privacy with a simple switch, addressing psychological, legal, and operational needs.


This article explores how smart glass and film by SFI enhance privacy and experience in mobile MRI units. We’ll examine how these units are structured, why privacy is vital, how smart glass transforms environments, real-world deployment examples, and comparisons between film and glass—highlighting retrofitting advantages.

The Purpose of Mobile MRI Units

Mobile MRI units serve multiple roles in modern healthcare. First, they bridge gaps in regions lacking permanent imaging infrastructure, delivering essential diagnostic services to rural or remote communities. Second, by supplementing hospital systems, they help alleviate overload, reduce wait times, and offer flexible scheduling in high-demand areas. Third, they prove invaluable during emergencies, military operations, or natural disasters, providing on-site imaging facilities where permanent infrastructure may be compromised. Lastly, they represent a cost-effective alternative to building fixed MRI installations, especially for institutions seeking to pilot MRI services before committing to larger investments.


What Do MRI Trucks Look Like and How Are They Built?

Mobile MRI units typically consist of either a truck (motorized chassis) or a towed trailer/caravan, both engineered to house a fully operational MRI scanner. The exterior shell is specialized for transportation, while the interior is meticulously compartmentalized into scanning, control, and preparation areas.

Inside, walls, ceilings, and floors form an RF-shielded Faraday cage—commonly made from copper, steel, or aluminum—to prevent external radio interference. Magnetic shielding is embedded in walls to confine the MRI's powerful field . HVAC systems—complete with waveguide filters for cabling, piping, and ventilation—ensure the interior climate remains stable without compromising shielding.


Integration of smart glass and film occurs here: either during manufacturing or as post-build enhancements, windows between patient and control rooms, or entrance doors, are fitted with switchable PDLC film or glass. These are wired into the unit’s electrical systems to allow instant opacity changes, ensuring privacy with a simple control mechanism.


The Critical Role of Privacy During MRI Procedures

Patients undergoing MRI scans are physically exposed, often wearing gowns and positioned closely within the scanner. This level of exposure makes privacy a core concern, from both psychological and legal standpoints. In permanent facilities, dedicated rooms with locking doors handle this—but mobile units require equal rigor in temporary or public settings. Smart glass allows staff to maintain a patient’s modesty, protecting visible patient identity and noise isolation while preserving dignity and adherence to medical privacy laws. This enhancement elevates patient comfort, which can notably reduce stress-induced movement—leading to higher-quality scans.


How Smart Glass Transforms the Mobile MRI Environment

Smart glass elevates mobile MRI units in multiple ways. With the flip of a switch, clear windows become opaque to create immediate visual privacy without obscuring natural light in other states. This dynamic control frees interior spaces from static curtains or blinds, maximizing the perception of space in compact units. PDLC and laminated glass also offer durable, hygienic surfaces that resist cleaning chemicals—critical in medical workflows.


Operationally, switchable glass surfaces integrate with remote monitoring systems, allowing technicians to ensure patient safety while obscuring visibility until scanning is complete. The transparent state can also facilitate natural light entry, reducing the clinical feel of confined units and enhancing patient comfort.


5. Smart Glass in Action: Real-World Mobile MRI Deployments

Rural European Communities In parts of Europe with low population density, mobile MRI units equipped with smart glass have reached rural clinics. Switching from transparent during entry to opaque during scanning ensures minimal patient anxiety. Feedback highlights increased acceptance and trust in imaging services—boosted by the perceived professionalism of a high-tech interior, not just clinical function.

Military and Disaster Field Hospitals Field hospitals benefit from smart glass in mobile MRI units deployed in conflict zones or disaster areas. Smart glass ensures rapid transition from interrogation to privacy mode—as needed. This layering of confidentiality is especially crucial where operational security and patient confidentiality intersect, delivering dignity amidst unpredictable environments.


Urban Hospital Expansion and Renovation

When hospitals undergo renovation or experience peak periods, mobile MRI trailers often temporarily replace fixed units. Smart glass makes these trailers feel integrated and permanent. Patients report reduced anxiety when scanning aboard units that offer a soothing, light-filled space rather than curtained isolation.


Design and Integration of Smart Glass in MRI Vehicles

Smart glass integration begins with structural planning. OEMs or retrofit specialists install factory-grade laminated switchable glass during new builds, furnishing robust privacy control behind MRI-grade shielding. For existing mobile units, SFI’s adhesive PDLC smart film serves as a low-impact retrofit—easily added to windows and panels without structural disruption or rewiring of HVAC or shielding systems.


Smart glass panels connect to the vehicle’s power—usually standard 110 VAC onboard supply—with controls near the technician’s console. Custom wiring ensures reliable operation without interfering with RF or magnetic shielding. Both film and structural smart glass meet medical-grade hygiene standards, with smooth surfaces resistant to disinfectants.

Maintenance is straightforward: no moving parts mean less wear, and performance tests show durability across thousands of switch cycles. Manufacturers typically back these systems with warranty commitments and performance guarantees, ensuring long-term ROI.


7. Smart Film vs. Smart Glass in Mobile MRI Use

In mobile MRI units, smart film is typically the preferred solution due to its ease of application. Unlike structural smart glass, which must be installed during manufacturing or major renovations, smart film can be applied directly to existing windows and partitions. This makes it ideal for retrofitting older units or updating current fleets without significant downtime or reconstruction. It delivers the same switchable privacy functionality while offering a faster, more cost-effective path to upgrade mobile imaging environments with minimal disruption.


Summary

Smart glass and film solutions play a transformative role in mobile MRI units—where patient privacy, comfort, and operational efficiency intersect. These units, engineered with RF/magnetic shielding and compact layouts, benefit greatly from switchable glass technologies that replace curtains and static partitions.


Deployments in rural regions, military field hospitals, and urban hospital expansions highlight the versatility and impact of smart glass in maintaining dignity and trust during imaging procedures. Adhesive smart film by SFI provides an ideal retrofit pathway for existing fleets, ensuring ease of adoption and strong ROI. Ultimately, integrating smart glass strengthens the patient experience, regulatory compliance, and the professional image of mobile diagnostic services.
