LG 14HQ901G-B: 14 by 17 Oxide TFT Digital X-ray Detector with 0.78 DQE
Authorized LG medical imaging equipment supplier. The LG 14HQ901G-B pairs the universally compatible 14 by 17 inch format with an Oxide TFT backplane for low-dose general radiography. The 14 by 17 size fits all standard table bucky systems and wall stands and works in both portrait and landscape orientation, covering the full general radiology exam list, while the Oxide TFT backplane raises detective quantum efficiency for dose reduction across every study it performs.
The detector reaches a 0.78 DQE at 0.1 lp/mm with a CsI scintillator, a 2560 by 3072 pixel matrix, a 358.40 by 430.08 mm active area, a 140 micrometer pixel pitch, and 16-bit conversion. It connects to a control box over a 7 meter magnetic main cable or dual-band IEEE 802.11 a/b/g/n/ac wireless, transferring a full image in 1.5 seconds wired or 2 seconds wireless. LG SW Grid software estimates and corrects scatter to reduce the need for a physical grid. At 3.0 kg with a rear-handle design, an IP68 seal, a 400 kg load rating, and a hot-swap battery rated for about 320 shots or 8.0 hours, it suits fixed rooms, portable systems, and rotation pools.

Oxide TFT Image Quality, 14 by 17 Versatility, and SW Grid
Three capabilities define the 14HQ901G-B. An Oxide TFT backplane delivers a high 0.78 DQE at 0.1 lp/mm for low-dose imaging, the universal 14 by 17 inch format fits every standard bucky and wall stand for the full general radiology exam list, and LG SW Grid corrects scatter in software to reduce the need for a physical grid. Full technical detail is in the expandable sections below.
Oxide thin-film transistors offer higher electron mobility and lower leakage current than amorphous silicon TFTs, so each pixel reads charge more efficiently from the photons that convert in the CsI scintillator, and electronic noise is lower. This supports a high detective quantum efficiency and reduced image lag, which lets diagnostic image quality be maintained at lower radiation dose.
DQE: 0.78 at 0.1 lp/mm
MTF: 84 percent at 0.5 lp/mm
Scintillator: Cesium Iodide (CsI)
A/D Conversion and Data Output: 16-bit
Low Dose Benefit: the higher DQE supports ALARA dose reduction across chest, spine, pelvis, and extremity studies, and is well suited to pediatric and serial imaging
LG SW Grid: software that estimates and corrects scatter radiation, reducing the need for a physical anti-scatter grid, with image quality LG states is comparable to grid-processed images, supported through the Acquisition Workstation Software sold separately
Active Area: 358.40 by 430.08 mm (14 by 17 inch), 2560 by 3072 pixels at a 140 micrometer pitch, in the universal format that fits standard table bucky systems and wall stands in portrait and landscape
Format Versatility: portrait covers chest PA and AP, spine, and femur, and landscape covers bilateral hips, shoulder, and pelvis, as a direct digital replacement for 14 by 17 inch CR cassettes
IP68: dust tight and water resistant to 1 meter for 30 minutes, cleanable for clinical use
Load Capacity: 400 kg uniform load and 200 kg point load for under-patient placement
Sensor Protection: carbon fiber plate over the panel, with a 384 by 460 by 15.6 mm body at 3.0 kg including the battery
Portability: a rear-side handle with sculpted handgrips and four-side chamfers for single-technologist and bedside handling
Battery and Connectivity: hot-swap battery rated for about 320 shots or 8.0 hours, swappable in one minute, with the detector connecting to a control box over a 7 meter magnetic main cable or dual-band IEEE 802.11 a/b/g/n/ac wireless
How the 14HQ901G-B compares against a standard a-Si flat panel detector:
The 14 by 17 inch format is the most clinically versatile detector size and the direct digital equivalent of the common CR cassette, so a department can upgrade from CR to the 14HQ901G-B without changing table bucky systems, wall stands, or positioning protocols. The Oxide TFT backplane then carries a 0.78 DQE across every exam the detector performs, which supports lower-dose protocols for chest, spine, pelvis, and extremity work, and SW Grid removes the need for a physical grid in portable and bedside settings.

Clinical Applications
Deployed across general radiography environments where universal 14 by 17 coverage, high DQE for reduced dose, and rugged portable construction provide clinical and operational value.
Chest PA and AP, abdomen, pelvis, spine, shoulder, hip, knee, and extremity all fit the 14 by 17 format in portrait and landscape, so a single detector handles the complete general radiology exam list without changing detectors or repositioning wall stands between studies.
The 0.78 DQE Oxide TFT backplane supports diagnostic image quality at lower exposure settings across all exam types, which gives facilities running dose tracking and ALARA programs a measurable path to cumulative dose reduction.
Higher radiosensitivity in children makes DQE especially important. The higher DQE of the 14HQ901G-B supports protocol adjustments that lower dose for pediatric chest, extremity, and abdominal studies in line with institutional pediatric dose goals.
The 14 by 17 format is the direct digital equivalent of the most common CR cassette, so upgrading from CR to the 14HQ901G-B requires no changes to table bucky systems, wall stands, or exam positioning, for a rapid and low-disruption conversion to digital radiography.
Wireless operation, a hot-swap battery, IP68 protection, a 3.0 kg rear-handle body, and a 400 kg load rating ready the 14HQ901G-B for bedside and ICU portable imaging, and SW Grid corrects scatter where a physical grid is impractical.
Portrait and landscape versatility covers bilateral comparison views, cross-table laterals, and full-limb studies, and the 14 by 17 compatibility with standard table and wall systems means no workflow change for orthopedic rooms already built for that cassette size.
Generator Compatibility, Control Box, and SW Grid
X-ray generator compatibility, the control box architecture, wired and wireless operation, SW Grid scatter correction, and battery workflow combine to fit the 14HQ901G-B into fixed rooms, mobile systems, and CR replacement projects. Expand each section for detail required by radiographers, IT administrators, and biomed teams.
The 14HQ901G-B uses standard DICOM communication for image transfer and worklist management. Auto Exposure Detection works with most radiographic generators, and an optional sync cable connects the control box to the generator for direct triggering where required. The control box connects to the acquisition workstation over a LAN cable. Medical Outfitters performs generator compatibility verification during pre-installation planning for every deployment.
The detector connects to a control box, which links to the acquisition PC and to the X-ray generator. In wired mode, a 7 meter magnetic main cable transfers a full image in 1.5 seconds for a 4.5 second total cycle. In wireless mode, dual-band IEEE 802.11 a/b/g/n/ac transfers a full image in 2 seconds for a 5 second total cycle, which suits portable and bedside use where a cable run is impractical.
LG SW Grid, supported through the Acquisition Workstation Software that is sold separately, estimates and corrects scatter radiation in software, which reduces the need for a physical anti-scatter grid. LG states the SW Grid image quality is comparable to images processed with a physical grid. This is most useful in portable and bedside imaging, where mounting and aligning a physical grid is difficult, and it removes the grid cut-off artifacts that come from grid misalignment.
The detachable battery is rated for about 320 exposures or 8.0 hours at a 90 second cycle and hot-swaps in about one minute while holding power so imaging is not interrupted. The system ships with two battery packs and a charger, and a full charge takes about three hours. A rear-side handle with sculpted handgrips and four-side chamfers, on a 3.0 kg body, makes the detector easy to carry and position for single-technologist and bedside work.

Frequently Asked Questions
Common questions from radiographers, imaging technology managers, and procurement teams evaluating the LG 14HQ901G-B for fixed rooms, mobile systems, and CR replacement.
The LG 14HQ901G-B is a 14 by 17 inch wireless flat panel digital X-ray detector that uses an Oxide TFT backplane with a CsI scintillator for general radiography. It reaches a 0.78 DQE at 0.1 lp/mm, which supports diagnostic image quality at lower radiation dose, and the 14 by 17 format is the universally compatible size that fits standard table bucky systems and wall stands in both portrait and landscape orientation.
The 14 by 17 inch format is the most versatile size in general radiography. It fits all standard table bucky designs and wall stands, supports portrait and landscape orientation for chest, spine, pelvis, and extremity studies, and matches the historical CR cassette size most departments already use. The 17 by 17 square LG 17HQ901G-B is the choice when full bilateral chest or full-spine single-exposure coverage is the priority, while the 14 by 17 is the universal format for mixed general radiology rooms.
Both share the 14 by 17 format, 140 micrometer pixel pitch, IP68 rating, and 400 kg load capacity. The 14HQ901G-B uses an Oxide TFT backplane for higher detective quantum efficiency and lower image lag, which supports lower-dose protocols, while the 14HQ701G-B uses an amorphous silicon TFT backplane. Choose the 14HQ901G-B for dose-sensitive protocols, pediatrics, and active dose reduction programs, and the 14HQ701G-B as a value option for high-volume general radiography.
SW Grid is LG software, supported through the Acquisition Workstation Software that is sold separately, that estimates and corrects scatter radiation in the image. This reduces the need for a physical anti-scatter grid, and LG states the SW Grid image quality is comparable to images processed with a physical grid. It simplifies portable and bedside workflows where mounting a physical grid is impractical.
Both. The detector connects to a control box over a 7 meter magnetic main cable for wired operation, which transfers a full image in 1.5 seconds, or over dual-band IEEE 802.11 a/b/g/n/ac wireless, which transfers a full image in 2 seconds. The control box connects to the acquisition PC over a LAN cable and to the X-ray generator over an optional sync cable.
The detachable battery is rated for about 320 exposures or 8.0 hours at a 90 second cycle, and it can be hot-swapped in about one minute, holding power during the swap so imaging is not interrupted. The system ships with two battery packs and a battery charger, and a full charge takes about three hours.
It is IP68 rated, dust tight and water resistant to 1 meter for 30 minutes, and holds a 400 kg uniform load and a 200 kg point load for under-patient placement. The sensor is protected by a carbon fiber plate, the body weighs 3.0 kg, and a rear-side handle with sculpted handgrips and four-side chamfers improves portability for single-technologist and bedside use.
