Detector performance instrument
DQEPro.
The only fully automated, IEC 62220-1 compliant system for measuring the detective quantum efficiency of medical x-ray detectors. Laboratory-grade measurement hardware and analysis software in a single portable instrument.
Capabilities
One instrument, complete coverage.
DQEPro replaces weeks of manual measurement with an automated, repeatable workflow — from data acquisition through report generation.
Automated acquisition
Define the exposure protocol and start the run. The system sequences exposures, repositions internal components, and captures data without operator intervention.
Integrated exposure chamber
Solid-state chamber with ultra-flat energy response and integrated HVL sensor to confirm correct x-ray spectrum with every test.
Standards-aligned analysis
DQE, MTF, and NPS computed per IEC 62220-1 (2003 and 2015 editions) with built-in validation including quantum-noise analysis.
Automated reporting
PDF, XML, and XLS output generated automatically — formatted for engineering review, 510(k) documentation, and cross-site comparison.
Multi-modality support
Configurable for radiography, mammography, fluoroscopy, CT, computed radiography, and dental systems.
Wireless detector support
Linearity analysis detects exposure truncation problems with wireless detectors and tests for uniform spacing and pulse width.
Configurations
Ship-ready, with modular options.
DQEPro ships in a base radiography configuration and extends through modular options to cover mammography, dynamic, and CT detector systems.
DQEPro
Base configuration for radiography systems with standard IEC spectra RQA-3 (50 kV), RQA-5 (70 kV), and RQA-7 (90 kV).
Multi-spectra option
Enables any radiography (tungsten tube) spectra from 50–90 kV and 3–12 mm Al HVL. Higher kV spectra available on request.
Mammography option
Extends DQE testing to mammography systems with frequency response characterization to 10 cycles/mm.
Dynamic option
Extends DQE testing to dynamic systems including pulsed fluoroscopy with pulse profile and frame lag analysis.
Carry-on form factor
Designed for the field, not the lab.
DQEPro ships in a rugged carrying case and deploys wherever your detectors are — manufacturing floors, clinical suites, or research facilities. No dedicated measurement lab required.
Sample reports
See what a full assessment produces.
Each test produces a complete detector characterization report. Raw, unedited PDFs across modalities.
Radiography
Standard radiography system tested at 1.0 µGy with quantum-noise analysis down to 0.2 µGy.
Wireless detector
Radiography with wireless detector, demonstrating integration window detection.
Mammography
Mammography system with 80% zero-frequency DQE extending to 10 cycles/mm.
Dynamic (25 fps)
Pulsed fluoroscopy at 25 frames/sec with pulse spacing and frame lag analysis.
Dynamic (5 fps)
Pulsed fluoroscopy at 5 frames/sec with advanced pulse shape analysis.
