X-Ray Quality Assurance Device Designed with Touchscreen Interface

A new measuring device combines accurate readings with the intuitive operation of a touchscreen. The device does not require any complicated menu settings: the sensor is simply connected to the base unit and the measurement is started without the need to select ranges or modes.

While the orientation-independent sensor captures all pertinent measuring parameters with a single exposure, the user-friendly touchscreen provides access to all required data such as dose, dose rate, half-value layer (HVL), kVp, total filtration, exposure time, pulses, and the corresponding waveforms.

The RaySafe X2, developed by Unfors RaySafe (formerly Unfors Instruments; Billdal, Sweden), is comprised of a base unit, an external sensor for radiofrequency (RF) measurements and a built-in mA sensor. When using both sensors, the device will display 12 parameters simultaneously. A simple swipe is all it takes to display parameter-specific waveforms. The X2 RF sensor, with its sophisticated stacked sensor technology, prevents the influences of heel effects on the measurements. A breakthrough in sensor design and circuitry means that the RaySafe X2 provides dose rate sensitivity, from 1 nGy/s for pulsed fluoroscopy and 50 nGy/s for continuous fluoroscopy. Because all exposures are saved in the base unit, measurement data remains available for reference and comparison purposes. The included X2 View software offers a range of additional analyses and provides an Excel interface for easy reporting.

“Our objective in developing the RaySafe X2 was to take quality assurance in diagnostic X-ray environments to the next level. The combination of an intuitive user interface and high-performance sensor technology not only simplifies the maintenance and functional checking of X-ray equipment but also reduces the likelihood of operator errors,” explained Mats Alm, vice president, diagnostic X-ray at Unfors RaySafe.

Moreover, the RaySafe X2 saves service engineers and state inspectors valuable time while at the same minimizing the inspection-related downtime of the X-ray system. RaySafe X2 is currently available and shipping.

Unfors RaySafe, Inc. is a subsidiary of the Swedish technology company Unfors RaySafe, AB, a supplier of solutions to measure, monitor, and manage radiation dose for equipment, staff, and patients.
