The difference, in pictures

What the other formats ask of you.

Reference images of conventional trailer and modular imaging units, next to what the Apex WalkIn MRI replaces them with: a 10" step-free entrance, a standard truck move and a level surface.

Patients climbing an external staircase to enter a conventional mobile MRI trailer — Conventional trailerEntry is around 60" up: an external staircase, or a lift cycle for every seated or stretcher patient.

Conventional mobile MRI trailer parked beside a hospital with its staircase and canopy deployed — Conventional trailer, sitedStairs, canopy and a raised deck take up space alongside the unit at every site.

Conventional mobile MRI trailer being towed on a highway by a tractor unit — Conventional trailer, movingMoves on standard truck, which is the one thing the trailer format gets right.

Crane lifting a modular imaging building from a trailer onto a prepared site — Modular unitComfortable inside, but placing it needs a crane and a lifting crew.

Modular imaging building being transported on a lowboy trailer along a highway — Modular unit, in transitOversize transport on a lowboy, not a standard truck move.

Prepared concrete pad and utility connections outside a hospital main entrance — Site worksModular and hybrid units expect a poured pad and permitted site works before arrival.

Apex WalkIn MRI

Ten inches from the ground, 52" double sliding doors, standard truck delivery. No Lift, no crane, no foundation, no building permit.

Swipe the table sideways to see both columns.

Feature	Apex WalkIn MRI	Conventional trailer
Ceiling height	110"	89" – 91"
MRI room width	92.5"	87"
Patient comfort	Spacious scan environment with a complete ceiling throughout the room	More enclosed scan environment; the ceiling ends where the MRI begins
MRI service	All service can be completed without opening a roof hatch	Some service procedures require opening a roof hatch
Patient entry	Step-free near-ground entry, no lift required	55" – 60" off the ground; single door 41" wide plus a patient lift and roll door

Layout

Four rooms, front to rear.

Front room

Electrical section: transformers, breakers, control panel, automatic transfer switch, batteries
Staff area and cabinets
Sink with hot and cold water
Humidifier
Supply and wastewater tanks, pumps and heater

Control room

Full glass RF door — the first trailer to feature one
Glass sliding entrance doors bringing daylight into the control room while keeping patient privacy
Changing area with bench, privacy curtain and secure storage for personal items
Storage cabinets, with overhead cabinets housing scanner, data and phone equipment
Trailer monitoring and alarms: HVAC, fire system, trailer status, CCTV and shock monitoring

Scan room

Cabinets for coil, phantom and accessory storage
Transport bracket and wiring for a contrast injector
LED skylights with RGB perimeter lighting
Roof hatch for future MRI replacement

Rear technical room

MRI electrical cabinets, filter panel and rear entry to the scan room
MRI cooling cabinet and MRI UPS
Fire suppression tank and fire panel
Shock logger alarm
Hospital connections: phone, data, fire, code blue and code red
Shore power plug, cable reel and cable entry flap

Electrical

Electrical inside, not underneath.

Apex houses the electrical section in its own part of the front room, rather than in a belly box beneath the trailer body.

Apex front room

Where the equipment livesInside the front room, in a separate section
Service accessFrom the control room — indoor service, easy access
Canadian powerOn-board 600V to 480V transformer; the site provides only a 600V plug and disconnect panel
Operating voltageOperates from both 600V and 480V

Belly box compartment

Where the equipment livesIn a belly compartment underneath the trailer body
Service accessOnly from outside; service requires crouching, exposed to the weather
Canadian powerNo room for the Canada-required transformer; each site buys a standalone 600V to 480V unit
Operating voltage480V only

Shore power

A cable reel, not a loose cable.

Apex stores the 75 ft shore power cable on a reel with a drip pan underneath.

Apex cable reel

Remote-controlled spooling
Manual unspooling with adjustable tension
Cable and plug securely stowed during transport
Drip pan underneath the reel

Cable stored loose in the belly

Manual pulling out and stowing of a heavy cable with a large plug
Rubbing on the edge of belly doors damages rubber gaskets over time
Cable and plug stowed loose in the belly compartment
Grime, snow and water from the cable enter the belly compartment

Transport

Warning lights the driver can read.

Visible in the driver's mirror. All green means the unit is OK to move; anything red means it cannot move until the fault is cleared.

Run flat engaged: On when the tires are automatically inflating or deflating.
Transport ready: Green when all doors are closed, suspension is at ride height and pressure is OK.
MRI ready: Green when the air bladder compressor is on.
MRI cooling OK: Green when the cooling cabinet reports no errors and cryo is working.
Batteries charging: Green when the 12V battery system is charging.
Fuel level OK: Green when fuel level is OK.
Low brake pressure: Red on low brake pressure.
Shore power connected: Green when the 75 ft shore power cable is plugged in and the site supply is live.
Cable reel stowed: Green when the shore power cable is fully reeled in and stowed for transport.
