LG Digital X-ray Detector with Oxide TFT – Model 14HQ901G
Oxide TFT · Superior DQE · 8‑hour battery · 3.0 kg lightweight design – The LG 14HQ901G represents the next generation of digital radiography. Oxide TFT technology delivers exceptional Detective Quantum Efficiency (DQE) and lower noise compared to a‑Si panels, while maintaining the rugged IP68 durability and 400 kg load capacity of the LG detector family.
Oxide TFT Advantage – Exceptional Image Quality
Oxide thin‑film transistors offer higher electron mobility and lower leakage current than amorphous silicon. This translates directly into higher DQE, reduced electronic noise, and sharper images at lower dose. See how the 14HQ901G compares to standard a‑Si detectors.

Frequently Asked Questions
Oxide TFTs have higher electron mobility and lower leakage current. This results in higher DQE (0.78 vs 0.66 at 0 lp/mm), reduced electronic noise, and better low‑dose performance. Image lag is also significantly reduced.
Under typical use (90‑second cycle), expect approximately 320 exposures or 8 hours of continuous operation. Hot‑swap capability allows indefinite runtime with spare batteries.
Yes. The detector supports standard DICOM and auto‑exposure detection with major generators (GE, Siemens, Philips, Canon, Shimadzu). Our team will verify compatibility during pre‑installation.
No. Calibration software is included and the detector maintains excellent stability. A simple monthly gain calibration is recommended.
