Product Overview
Portable X-ray machines have traditionally forced practitioners to make a harsh trade-off between generator power (output kW) and carrying weight. Units weighing 15 kg or more frequently induce repetitive strain injuries among visiting radiologic technologists. The RadField UltraPort 90 approaches this engineering dilemma by deploying high-frequency inverter technology paired with lithium iron phosphate chemistry, holding total generator mass to 7.8 kg while delivering an output ceiling of 90 kVp at 30 mAs (sample rating).

Main Features & Engineering Highlights
High-Frequency Inverter Monoblock
Operates at 70 kHz to produce a flat, low-ripple direct-current potential, minimizing soft-tissue radiation while maximizing penetrating photon yield.
LiFePO4 Modular Battery Chemistry
Provides over 2,000 charge cycles before dropping below 80% capacity, operating safely across wide ambient temperature swings (-10°C to 45°C).
Pre-Programmed Anatomical Body Programs (APPs)
One-touch selection for adult and pediatric extremities, chest, and lateral cervical projections, reducing setup time between exposures.
Integrated Dual-Beam Laser Collimator
LED illumination with automatic shutoff timer and crossing laser pointers for accurate 100 cm and 180 cm SID verification.
Pros and Cons
Advantages & Strengths
- •Class-leading generator power-to-weight ratio under 8 kg
- •Dual hot-swappable lithium iron phosphate (LiFePO4) battery packs
- •Integrated touch interface with pre-programmed anatomical body part programs (APPs)
- •Sub-3-second wireless image transfer to tablet acquisition console
Limitations & Trade-Offs
- •Output limited to 90 kVp / 30 mAs (unsuitable for bariatric lumbar spines)
- •Optional carbon-fiber carrying case sold separately
- •Battery recharge time is 90 minutes when completely depleted
Performance Considerations & Photon Output
In bench evaluations with a sample torso phantom, the UltraPort 90 provided clean, high-contrast chest and distal extremity projections when coupled with a modern Cesium Iodide flat panel detector. However, with its sample maximum ceiling of 90 kVp and 30 mAs, the generator reaches its operational limits when imaging dense abdominal structures or lateral lumbar spines on heavier patients. Technologists should understand that portable generators under 3 kW cannot substitute for a 50 kW hospital room suite in spine or pelvis cases.
Ease of Use & Radiation Workflow
From storage trunk to live diagnostic exposure, the setup workflow averages under 3 minutes. The touch control panel features high-contrast glove-friendly buttons, and the audible exposure buzzer provides clear feedback across ambient clinic noise. The mechanical stand locks smoothly with a pneumatic gas spring.
Portability & Mechanical Footprint
At 7.8 kg, the generator can be carried short distances one-handed by its top grab handle. For longer hospital rounds or parking lot transits, the companion folding wheeled stand collapses into a compact 1.1-meter footprint that fits easily into passenger sedan trunks.
Connectivity & PACS / EMR Integration
The system links via dual-band Wi-Fi to a ruggedized acquisition tablet running standard DICOM 3.0 Modality Worklist (MWL) and Storage Commit protocols. Image preview is rendered in 2.8 seconds, enabling quick clinical repositioning before departing the patient room.
Detector Compatibility & Scintillators
Equipped with a universal AED (Automatic Exposure Detection) interface, the generator triggers wireless flat panel detectors from various third-party brands without needing physical sync cables.
Target Clinical Environments & Suitability
Intended Facilities
- •Sports medicine sidelines and mobile athletic training facilities
- •Disaster response, field triage hospitals, and military forward bases
- •Rural urgent care clinics lacking dedicated lead-lined suites
- •Home health and nursing facility visiting radiology services
Who It Is Best Suited For
- •Radiologic technologists seeking low lifting strain during field work
- •Mobile diagnostic services requiring high battery uptime
- •Outpatient clinics handling extremity, chest, and pediatric imaging
Important Considerations Before Purchase
- ⚠Confirm whether your clinical caseload requires dense abdominal or bariatric spine views that exceed 90 kVp.
- ⚠Verify state and regional radiation health agency registration requirements for portable units.
- ⚠Budget for mobile lead barriers or certified operator shields (0.5 mm Pb equivalent) during field use.
- ⚠Check whether your existing flat panel detector has reliable Automatic Exposure Detection (AED).
Alternative Equipment to Consider
PortaRay MaxGen 100
Heavier unit (9.2 kg) but reaches 100 kVp at a slightly lower entry cost.
View System Specs →TraumaGlide Motorized Mobile DR
Full 32 kW motorized mobile cart for hospital bedside imaging, though far heavier.
View System Specs →Frequently Asked Questions: RadField UltraPort 90
Yes. The battery charger operates on standard 110V/220V household AC outlets, and the unit can also be exposed while tethered to line power if the battery is depleted.
Under typical sample clinical conditions (70 kVp at 4 mAs), the dual battery pack delivers approximately 250 exposures per full charge.
In many mobile and urgent applications, temporary mobile lead shielding or certified operator clearance distances are utilized, but local radiation protection regulations always govern room shielding criteria.
Final Review Summary
The RadField UltraPort 90 is an impressively engineered lightweight portable generator that excels at extremity and chest diagnostics in mobile and remote settings. While limited in heavy torso radiography, its ergonomic weight and clean digital workflow make it a premier choice for mobile imaging providers.
