At this year’s RSNA annual conference in Chicago, attendees were able to see LG Business Solutions USA’s 510(k) pending oxide-based thin-film-transistor (TFT) Digital X-ray Detector.
Set to be available in sizes 14x17 inch and 17x17 inch, the device’s oxide-based TFT enables it to provide high Detective Quantum Efficiency (DQE). This makes it more efficient at transferring energy and converting electrons into an actual image. In addition, the size of the model of cesium in the detector has been raised from 300 micrometers in previous models to 500, allowing for more dose reduction.
“It can be used as a retrofit or upgrade solution, in addition to incorporating with an OEM solution from any one of the industry X-ray manufacturers,” Chris Anderson, senior account manager for LG Electronics, told HCB News.

The TFT is expected to accelerate electron transfer speeds to almost 30 times faster than a conventional a-Si TFT. The increased thickness of the Cesium also improves the DQE of the oxide-based TFT by 28% at 1 p/mm. Another component is the LG Workstation Software version 3.0, which can analyze X-rays and alert providers to abnormalities. It provides an abnormality score with a colored heat map or contour that marks any lesions detected and sends images directly from the DXD to a connected workstation within seconds. The device also utilizes LG SW Grid to estimate and correct scattered radiation.
The oxide-based TFT Digital X-ray detector comes with concave edges and convenient grips that can withstand a 1.5-meter drop. Additionally, it has a built-in micro battery that allows the detector to stay on for approximately one minute when replacing the battery to minimize workflow disruptions and eliminate the need to reboot the device.
LG also showed its soon-to-be-released 21-inch, 3-megapixel diagnostic monitor. The lightweight solution comes with a one-click ergonomic stand for adjusting height, tilt and pivot to reduce chronic pain caused by long hours of viewing and poor posture.
The device displays radiological images with a resolution of 1536 x 2048 pixels and offers advanced localized brightness control. Users can review specific parts of MR and CT images more closely with the solution’s Focus View function, which offers magnification and brightness adjustment. It also has multiple sensors to optimize any diagnostic room environment, can automatically adjust luminance to stabilize brightness, and optimize brightness for ambient lighting.
And when no motion is detected, the monitor automatically shuts the display off to save energy and extend its lifespan. Automatic hardware calibration is accessible without additional equipment and improves image quality and consistency while reducing required staff and ongoing costs.
The 21-inch, 3-megapixel diagnostic monitor is also 510(k) pending. Both solutions are expected to be on sale in 2022.
