Display firm LG Business Solutions USA launched a new oxide-based thin-film-transistor (TFT) digital x-ray detector and 3-megapixel (MP) diagnostic monitor this week at the RSNA 2021 meeting in Chicago.

The wireless 14 x 17-inch detector (model 14HQ901G, which is not yet for sale) will use an oxide-based TFT design to deliver high detective quantum efficiency (DQE). The firm increased the cesium iodide thickness of 14HQ901G from 300 um to 500 um, which improved the DQE of the oxide-based TFT by 28% at 1 lp/mm.

The new detector has concave edges and grips built to withstand a 1.5-m drop. It will feature LG Acquisition Workstation Software version 3.0 (not yet available), which can analyze x-rays and inform the medical provider of any abnormalities. Images sent directly from the detector to a connected workstation with the software can be viewed within seconds; plus, the LG SW Grid estimates and corrects scattered radiation.

The 21-inch diagnostic monitor (model 21HQ513D-B, also not yet for sale) will introduce localized brightness control and a resolution of 1536 x 2048 pixels to support radiological image review, analysis, and diagnosis. The portrait-oriented monitor provides a maximum brightness of 1,100 nits with a 1,800:1 contrast ratio and multiple sensors to enable precise review of digital images.

The backlight sensor automatically adjusts luminance to stabilize brightness for consistent imagery and the auto-luminance sensor adjusts to ambient lighting conditions. The built-in presence sensor automatically turns off the display when no motion is detected and the front sensor enables automatic hardware calibration without additional equipment.

The monitor has a lightweight body and one-click ergonomic stand so users can adjust height, tilt, and pivot to help reduce chronic pain caused by poor ergonomics.
