TXI (Texture and Color Enhancement Imaging)
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 more clearly define subtle tissue differences.1
TXI technology is not intended to replace histopathological sampling as a means of diagnosis.
