Shedding light with two lasers

Fujifilm has adopted lasers for the transnasal endoscope, which is helpful for early detection of stomach cancer. White light and BLI—technology to control these two lasers will change the frontlines of medicine.

1.Adoption of lasers for the endoscope inserted through the nose

Many Japanese nationals are inflicted with stomach cancer. There is data* that indicates approximately 50,000 people die of stomach cancer every year. However, stomach cancer is a disease that can usually be cured with early detection.

2.The two lasers: a bright white light and blue-colored BLI light

The transnasal endoscope with lasers combines two lights with different wavelengths to illuminate the part being observed. The bright white light projects a sharp, vivid image, while the blue BLI light accentuates the fine veins on the surface of mucous membranes. The brightness of the white light and BLI light can be fully controlled, either when observing a wide range or when zooming in to detect abnormalities in the stomach. This makes it easier to find even the slightest abnormality.

3.Laser control technology and image processing technology that will change the frontlines of medicine

Lasers have features such as strong light emission, good directional quality, and being easy to control. These bring significant advantages to transnasal endoscopes, such as being able to make high-definition images even sharper.
Precise laser control technology and original image processing technology. Fujifilm’s technology cultivated in the field of photography is about to change the frontlines of medicine.
