Mobile X-Ray Equipment: Types of Units and Where Each One Fits

What a mobile X-ray unit is

A mobile X-ray unit is a self-contained radiography system on wheels, with a generator, tube, collimator and control panel, taken to the patient rather than the patient being taken to the radiology room. It is used in intensive care, emergency, wards, recovery, theatres and neonatal units where the patient is too ill or unstable to move.

Unlike a fixed room, a mobile unit works with the building around it: lifts, corridors, bed spaces and mains sockets. Those practical limits shape the choice more than the technical specification does.

Analog and digital mobile units

Analog mobile units use film or a CR cassette and send images to a reader later. Digital mobile units, often called mobile DR, use a flat-panel detector, usually wireless, so the image appears at the console in seconds. Digital units dominate new purchases because of speed, easy PACS connection and fewer retakes.

Villa's Visitor T30 units and Perlove's PLX M5320 are digital mobile systems. The Visitor T30 M-DR is described as a high-end motorised, battery-powered digital unit with 32 kW or 40 kW generators and a 35 x 43 cm portable detector, while the PLX M5320 combines a 50 kW generator with a 17 x 17 inch wireless detector. For detector details see wireless flat panel detector.

Manual and motorised drive

Manual units are pushed by the operator. They are light and simple, which suits small units and short distances, but they become tiring over long corridors. Motorised units have a driven wheel, making heavy units easier to move, climb ramps and manoeuvre in lifts, at the cost of added complexity and weight.

The Visitor T30 M-DR has a motorised drive and a front bumper with anti-collision function, and the PLX M5320 has motorised, power-assisted movement, with a separate lithium battery for driving and a supercapacitor for exposures. Hospitals with large sites and ICU floors usually favour motorised drive.

• Analog: film or CR, lower entry, slower workflow
• Digital: flat-panel detector, immediate image
• Manual: lighter, simpler, shorter distances
• Motorised: heavy units, long routes, ramps and lifts
• Handheld: very light, limited power, specific uses

Telescopic and rotating arm designs

The tube support determines how you position over a bed. A telescopic arm extends toward the patient and is useful where the unit must approach from the foot or head of the bed. A rotating column lets the arm swing so that the unit can stand parallel to the bedside, which helps in narrow bays and crowded ICUs. The Visitor T30 R-DR is built around a rotating column for exams parallel to the bedside, aimed at space-constrained areas, while the T30 M-DR has a column that rotates plus or minus 320 degrees and a telescopic arm.

Think about the typical bed layout in your wards before choosing. A unit that cannot reach the tube over the patient without moving the bed is not practical.

Ultra portable and handheld X-ray devices

Ultra portable X-ray machines are small, handheld or lightweight units designed for extremity and limited imaging, field use or remote sites. They have much lower output than a hospital mobile unit and are not a replacement for one in ICU or general ward work. They also carry specific radiation-protection requirements, so check regulatory conditions with the relevant UAE authorities before buying.

For the main wards, a motorised digital mobile unit is the more usual choice. Compare mobile and fixed systems in portable vs fixed X-ray and see how mobile units are used in ICU bedside X-ray.
