Oxide TFT (Indium Gallium Zinc Oxide) thin-film transistor substrate achieves significantly lower leakage current than amorphous silicon, enabling more efficient conversion of X-ray photons into electrical signal. The 14HQ901G-B’s 0.78 DQE at 0 lp/mm represents an 18% improvement over the 0.66 DQE of standard a-Si detectors.

In clinical terms, higher DQE means the same diagnostic image quality can be achieved with a lower patient dose – or alternatively, improved image contrast and noise at equivalent dose settings. This makes the 14HQ901G-B particularly well-suited to pediatric protocols, dose-sensitive serial imaging, and facilities with active ALARA dose reduction programs.

• 0.78 DQE @ 0 lp/mm – 18% above standard a-Si
• Lower leakage current through Oxide TFT substrate
• Supports ALARA dose reduction protocols across all exam types
• 14-bit output for broad dynamic range in mixed-exposure environments
• CsI scintillator for high-efficiency photon conversion

The 14×17 inch (35×43 cm) format is the most clinically versatile detector size. It is the direct digital equivalent of the standard CR cassette size that the vast majority of general radiology departments already use – simplifying CR-to-DR upgrades without changes to table bucky systems, wall stands, or positioning protocols.

Portrait orientation covers full-length chest PA/AP, full-spine segments, and full-length femur. Landscape orientation handles bilateral shoulder, hip comparison, and broad pelvis studies. The 14×17 format is also compatible with cross-table lateral hip and lateral L-spine positioning – making it the one-size-handles-all format for mixed general radiology rooms.

• 35 x 43 cm (14×17 in) active area
• Portrait: chest PA/AP, spine, femur
• Landscape: bilateral hips, shoulder, pelvis
• Direct replacement for 14×17 CR cassette systems
• Compatible with all standard table bucky and wall-stand systems

The 14HQ901G-B is rated IP68 – fully dustproof and resistant to water submersion, allowing use with hospital-grade disinfectants and in high-humidity environments. The 400 kg static load rating permits under-patient placement without protective padding or positioning aids, supporting direct table-top and stretcher-side workflows.

The carbon fiber composite housing achieves the high load rating while keeping the detector lightweight enough for single-technologist portable use. Drop resistance from 1.0 m provides additional protection for the handling demands of busy radiology departments and mobile imaging operations.

• IP68 – dustproof and water submersion rated
• 400 kg (880 lb) static load – direct under-patient use
• 1.0 m drop resistance
• Carbon fiber composite housing
• Compatible with hospital-grade surface disinfection protocols

The 14HQ901G-B supports both wired and wireless (Wi-Fi 802.11 a/b/g/n) operation. Auto Priority (AP) mode automatically manages the transition between wired and wireless connections based on signal availability, maintaining uninterrupted image transfer without technologist intervention.

The hot-swap battery system allows battery replacement during active imaging sessions without powering down the detector. For facilities running continuous imaging shifts or using the detector across multiple portable units, hot-swap capability eliminates the imaging gaps that non-swap battery systems introduce during charging cycles. The integrated OLED status display provides real-time visibility of battery level, Wi-Fi signal strength, and connection status.

• Wi-Fi 802.11 a/b/g/n wireless operation
• Auto Priority (AP) mode – automatic wired/wireless management
• Hot-swap battery – ~200 exposures per charge
• OLED display – battery, signal, and status readout
• Wired mode – under 4 seconds image read speed

The 14HQ901G-B integrates with standard DR generators via DICOM 3.14 interfaces including Modality Worklist, DICOM Storage, and Modality Performed Procedure Step. This broad compatibility supports connection to all major PACS platforms without proprietary middleware.

• DICOM 3.14 – Worklist, Storage, Print, MPPS
• Compatible with GE, Philips, Sectra, Agfa, Carestream PACS
• Standard AEC/trigger input for all generator types
• Supports multi-room and rotation pool configurations

• FDA 510(k) cleared for diagnostic radiography
• CE marked for European regulatory compliance
• IEC 62494-1 compliant (Exposure Index standard)
• DICOM 3.14 full compliance
• Compatible with standard flat-panel QA software and tools

The 14×17 format fits all standard table bucky systems without modification and supports both portrait and landscape orientation – covering the full general radiology exam list. The 17×17 square format has advantages for bilateral chest and full-spine single-shot coverage, but the 14×17 is the more universally compatible and operationally flexible choice for mixed-use general radiology rooms performing the complete range of studies.

The 14HQ901G-B achieves 0.78 DQE at 0 lp/mm via its Oxide TFT substrate. Higher DQE means more image signal extracted per X-ray photon, allowing the same diagnostic image quality to be maintained at lower dose settings. Clinically, this enables mAs reductions across standard protocols while preserving image quality – reducing cumulative patient dose for serial studies and dose-sensitive populations.

Both share the 14×17″ format, 140um pixel pitch, IP68 rating, and 400 kg load capacity. The 14HQ901G-B uses Oxide TFT (0.78 DQE) while the 14HQ701G-B uses a-Si TFT (0.66 DQE). Choose the 14HQ901G-B for dose-sensitive protocols and pediatric applications; choose the 14HQ701G-B for high-volume general radiology where proven a-Si technology and lower acquisition cost are the primary drivers.
