Digital Detector – LG 17HQ701G-B

Amorphous silicon thin-film transistor substrate has been the dominant technology in flat panel digital radiography for over two decades. Deployed in millions of installations worldwide, a-Si TFT offers well-characterized performance, stable long-term imaging behavior, and compatibility with the full ecosystem of DR acquisition software, image processing algorithms, and QA tools.

The 17HQ701G-B achieves 0.66 DQE at 0 lp/mm and 0.43 DQE at 1 lp/mm – delivering diagnostic-grade chest, abdomen, and spine images for the full range of general radiology exams. For high-volume departments where consistent throughput and predictable total cost of ownership matter more than the incremental DQE gain of newer oxide substrates, a-Si TFT remains the practical choice.

The 430×430 mm square active area captures full adult bilateral chest fields in PA and AP projections without cropping lateral chest walls, even in large patients. For spine studies, the square format captures thoracic and upper lumbar vertebrae in a single exposure, reducing the number of images and repositioning events needed for full-spine surveys.

Eliminating stitching software requirements means no stitching artifacts at image boundaries and no additional processing time between acquisition and PACS delivery. For high-volume chest departments performing hundreds of studies per day, the time savings per exam accumulate to measurable throughput improvements across the department.

IP68 rating: Dust-tight and submersible. Tolerates fluid spills, cleaning solutions, and hospital-grade disinfectants without damage to the panel or electronics.
Load capacity: 400 kg uniform load for 60 seconds, 200 kg point load. Supports full patient weight directly on the detector – critical for AP, trauma, and portable bedside workflows where the detector is placed under the patient.
Drop resistance: Tested to 1.5 meters per IEC 60601-1 – the standard drop height accounting for falls from standing height in clinical environments.
Shock monitoring: Built-in accelerometer logs impact events, enabling service teams to identify damage from shock versus normal imaging use.

Hot-swap battery: The Li-ion battery can be replaced in under 60 seconds without powering down the detector or losing stored images. A 2-slot charger keeps a second battery ready, enabling unlimited runtime across all-day shifts in high-volume departments.
OLED status display: Shows battery level, wireless signal strength, remaining storage, and connection mode at a glance – without returning to the acquisition console.
Access Point mode: The 17HQ701G creates its own Wi-Fi access point for direct device connection, enabling bedside and point-of-care imaging without requiring facility network infrastructure.
On-board storage: 200 images stored locally when offline, forwarded automatically when connectivity resumes.
