How Does the MinXray TR90B Support Imaging Without AC Power?

The defining advantage of the TR90B is its ability to perform diagnostic imaging independently of wall power. Its rechargeable battery system allows healthcare providers and veterinary professionals to perform examinations in remote locations, mobile environments, and field settings where access to electricity may be limited.

Rechargeable Lithium-Ion Battery System

The TR90B includes two quick-change lithium-ion batteries that support hundreds of exposures per charge under typical operating conditions. The quick-change battery design minimizes downtime by allowing batteries to be replaced quickly in the field, helping providers maintain productivity throughout the day.

High Power Mode

The TR90B features High Power Mode, increasing generator output by up to 50% when operating between 82 and 90 kV. This additional output expands the range of examinations that can be performed while maintaining the portability expected from a battery-powered X-ray generator.

Where the MinXray TR90B Fits Best

The TR90B is designed for organizations that perform diagnostic imaging in locations where dependable AC power may not be available. Its battery-powered design expands imaging capabilities in remote, mobile, and field-based healthcare environments.

Healthcare & Veterinary Settings

Typical environments include:

• • Mobile imaging providers
  • Home healthcare programs
  • Nursing homes and long-term care facilities
  • Hospitals
  • Emergency response teams
  • Disaster relief operations
  • Veterinary practices
  • Equine practices
  • Livestock operations
  • Wildlife and zoological medicine

Common Diagnostic Examinations

When paired with a compatible digital detector, the TR90B supports a variety of routine diagnostic examinations, including:

• • Chest imaging
  • Extremities
  • Abdomen
  • Skull
  • Equine distal limb imaging
  • Companion animal orthopedic imaging

Its battery-powered design allows providers to perform these examinations in locations where transporting patients or accessing external power may be difficult.

Portable Design That Supports Daily Imaging

The TR90B is engineered to simplify transportation, setup, and operation for providers who perform imaging across multiple locations throughout the day.

Lightweight 15 lb Design

Weighing approximately 15 lb (6.8 kg), the TR90B remains easy to transport between facilities, vehicles, and field locations while eliminating the need for an external power source during operation.

Hundreds of Exposures per Charge

The rechargeable lithium-ion battery system is designed to deliver hundreds of exposures on a single charge. Because the generator includes two quick-change batteries, providers can continue working with minimal interruption while one battery is recharged.

Programmable Exposure Techniques

Users can store up to five programmable exposure techniques to improve consistency and reduce setup time for frequently performed examinations.

Exposure Switch & Working Distance

The TR90B includes a two-stage deadman exposure switch that allows operators to maintain an appropriate working distance during exposures while providing flexibility in a variety of imaging environments.

Technologies Behind the TR90B

The MinXray TR90B combines battery-powered portability with proven generator technology to support dependable diagnostic imaging beyond the traditional X-ray room. Its integrated technologies are designed to maximize uptime, simplify operation, and deliver consistent performance in demanding mobile imaging environments.

Computer-Controlled High-Frequency Generator

The TR90B utilizes a computer-controlled high-frequency converter with a Pulse Frequency Modulation (PFM) high-frequency inverter system to produce stable X-ray output while maintaining the compact size expected from a battery-powered portable generator.

Rechargeable Lithium-Ion Battery System

The TR90B includes two quick-change lithium-ion batteries designed to provide hundreds of exposures from a single battery charge. Because one battery can be charged while the other remains in use, providers can continue imaging with minimal interruption throughout the day.

High Power Mode

High Power Mode increases generator output by up to 50% when operating between 82 and 90 kV. This additional output expands the generator’s imaging capabilities while preserving the portability that makes the TR90B well suited for remote and mobile imaging.

Precision Light Beam Collimator

The integrated Mikasa R-300V collimator features a continuously adjustable light field with dual integrated laser pointers that indicate both the central ray and positioning distance. This helps simplify positioning while supporting accurate beam alignment in a variety of imaging environments.

Rugged Housing for Mobile Use

The TR90B is built for demanding mobile imaging environments with a ribbed shock-absorbing outer housing, hard rubber impact bumpers, and a durable five-layer exterior finish. Its collimator is mechanically isolated from the X-ray tube, helping reduce the likelihood of damage if the collimator experiences an impact during transport or daily use.

Is the MinXray TR90B Right for Your Organization?

The MinXray TR90B is designed for organizations that need dependable portable X-ray imaging without relying on external AC power. Its lightweight design, rechargeable battery system, High Power Mode, and rugged construction make it well suited for mobile imaging providers, hospitals, home healthcare programs, long-term care facilities, emergency response teams, and veterinary practices that routinely perform imaging in remote or field-based environments.
