Gastroscopy

BLI is used in proximity magnification to observe blood vessels and superficial structures of the mucous membranes. The upper gastrointestinal endoscope ensures excellent vision while having a maximum optical magnification ratio of about 135 times (on 19-inch LCD monitor)

Concept of “Two Lasers”

LASEREO uses two lasers with different wavelengths. It creates illumination suitable for white light observation and BLI observation. The white light mode laser excites phosphors to create white light illumination (wavelength: 450nm±10nm). The BLI mode laser is used as high-contrast signals to obtain information about vascular pattern and surface pattern (wavelength: 410nm±10nm). By changing the intensity ratio of the two types of lasers, four observational modes can be selected through a combination of image processing with illumination suitable for white light observation and narrowband light observation.

BLI (Blue LASER Imaging)

The short wavelength narrowband light observation BLI shines short wavelength laser light suitable for vascular pattern observation and obtains high- contrast signals which then undergo image processing. Images suitable for observation of vascular pattern and surface pattern are obtained.

Observational Modes Obtained by Changing the Intensity Ratio

By changing the intensity ratio of the two types of lasers, four observational modes can be selected through a combination of image processing with illumination suitable for white light observation and narrowband light observation.

Lower Power Consumption and No Need for Lamp Exchange.

Compared with conventional xenon lamps of 300W, laser light source consumes only about 10W of power. It is recommended to replace xenon lamps every 500 hours when endoscopes of such lamps are used for 1,000 hours per year. The guideline is to replace 12 lamps in 6 years. Laser light source does away with these inconveniences and saves time and money.
