Procedure information


Scope: GIF-EZ1500

Case: Multiple gastric polyps (Benign)

Organ: Stomach

Patient information: F, 50

Medical history: History of chronic iron deficiency anemia and dyspepsia

1. WLI

#WLI #A3 structure enhancement

Multiple sessile polyps of <1cm sizes noted in the body of the stomach

2. TXI™ technology mode 1

#TXI Mode 1 #A3 structure enhancement

TXI™ technology mode 1 image shows color and structural image enhancement compared to WLI. There is increased brightness in the darker areas.

3. TXI mode 2

#TXI Mode 2 #A3 structure enhancement

TXI™ technology mode 2 shows enhancement of brightness and texture compared to WLI. The color tone of mode 2 is more similar to WLI than mode 1.

4. WLI

#WLI #A3 structure enhancement

Single sessile polyp of >1cm size noted in the body of the stomach

5. TXI™ technology mode 1

#TXI mode 1 #A3 structure enhancement

TXI™ technology mode 1 shows color and structural image enhancement compared to WLI. There is increased brightness in the darker areas.

6. TXI™ technology mode 2

#TXI mode 2 #A3 structure enhancement

TXI™ technology mode 2 shows enhancement of brightness and texture compared to WLI. The color tone of mode 2 is more similar to WLI than mode 1.1

7. WLI

#WLI #A3 structure enhancement

Multiple sessile polyps of <1cm sizes noted in the body of the stomach

8. TXI™ technology mode 1

#TXI mode 1 #A3 structure enhancement

TXI™ technology mode 1 shows color and structural image enhancement compared to WLI. There is increased brightness in the darker areas.

9. TXI™ technology mode 2

#TXI mode 2 #A3 structure enhancement

TXI™ technology mode 2 shows enhancement of brightness and texture compared to WLI. The color tone of mode 2 is more similar to WLI than mode 1.1

Overall Comment

TXI™ technology can enhance brightness selectively in dark areas of endoscopic images and can enhance subtle tissue differences1 such as slight morphological and/or color changes over conventional enhancement methods including structure enhancement and color enhancement. Comparing TXI™ technology with conventional white light imaging (WLI) for real-world image processing, TXI™ technology can achieve image enhancement with characteristics of WLI appearance while preventing over-enhancement observed in other methods. TXI™ technology has two modes, mode1 and mode 2. Enhancement of brightness and texture is similar in both modes. The color contrast is enhanced with TXI mode 1 whereas TXI mode 2 has a more natural color tone as no color enhancement is performed. Overall, TXI™ technology provides a balance of improving image features important for the physician searching for abnormalities (selective increase in brightness, color separation, and texture enhancement) while minimizing gross changes that may negatively impact familiarity (naturalness).
