The update blends color-contrast enhancement and texture-highlighting technology into one view to help clinicians better visualize tissue patterns and potential lesions.
Olympus Corp announced the launch of the NBI+TXI observation mode, which combines narrow band imaging (NBI mode) and Texture and color enhancement imaging (TXI mode) into a single view, to the Evis X1 endoscopy system CV-1500 video system center.
Sales of the Evis X1 endoscopy system featuring the NBI+TXI mode will begin in Japan in November 2025, with launches in other regions to follow pending local regulatory approvals.
CV-1500
Since its initial launch in April 2020, the Evis X1 endoscopy system has supported healthcare professionals with advanced imaging technologies including TXI mode, NBI mode, and RDI mode (red dichromatic imaging). These proprietary innovations have contributed to more precise observation and treatment of gastrointestinal and respiratory diseases, including cancer, according to a release from Olympus Corp.
The NBI+TXI mode is designed to strengthen the Evis X1 endoscopy system’s diagnostic capabilities by enhancing the brightness correction and contrast information of NBI mode. This aimsto enable clearer visualization in darker areas of the image and sharper definition of vascular and mucosal patterns, which can contribute to improved detection and diagnostic accuracy for lesions, including those associated with cancers.
NBI mode, first introduced globally in 2006, brought a change to endoscopic imaging by improving visibility of features that were previously difficult to detect. The CV-1500 incorporates the latest NBI mode, achieving improved brightness compared to the original NBI mode. TXI mode, introduced with the CV-1500, further aims to improve the visibility of lesions through its image enhancement technology when used with conventional light observation.
Combining NBI and TXI
The combination of these two technologies in the CV-1500, the NBI+TXI observation mode is expected to further enhance and optimize the contrast information in NBI mode images, supporting more precise endoscopic examinations and treatments, according to a release from Olympus.
“We know that early detection improves patient care and outcomes,” says Kurt Heine, senior vice president and general manager for gastroenterology at Olympus, in a release. “Olympus is committed to providing the advanced endoscopic imaging physicians need to clearly visualize the GI tract and provide timely diagnoses and treatment. We’re excited to expand upon the innovations of our Evis X1 endoscopy system with this combined imaging mode capability and continue elevating the standard of care.”
