Texture and Color Enhancement Imaging

One of several new technologies available with the EVIS X1™ endoscopy system, Texture and Color Enhancement Imaging (TXI™) technology is designed to enhance image information by combining three image processing algorithms – brightness correction of the dark part of the image; color difference expansion processing; and texture component emphasis processing.¹ The image is captured using white light, then TXI technology is applied during post-processing; therefore, the color appearance of the final image is similar to white light, making the viewing of lesions more relatable for the user.²

Early detection is critical for cancer prevention and decreasing mortality. A 1% increase in the adenoma detection rate (ADR) results in a 3% decrease in the risk of interval cancer and a 5% decrease in the risk of fatal interval colorectal cancer. However, precursor lesions are often tiny and easy to overlook, so good visibility is essential in characterizing and treating these lesions more effectively.^3,4

With that in mind, TXI technology was designed to increase the visibility of potentially suspicious lesions and polyps by enhancing image color and texture during endoscopic screening.¹ It may reduce miss rates for inflammation and early mucosal changes,¹ which may provide an endoscopist with the confidence they need to choose the right treatment option.

How It Works

The incoming image is split, and the texture and brightness are enhanced before the separate images are merged back together. Additional color enhancements are made to define subtle tissue differences more clearly.²

The following video explains how TXI technology works and its purpose during an endoscopic procedure.
