TXI: The New White Light

Texture and Color Enhancement Imaging (TXI)

Early detection is critical for cancer prevention and decreasing mortality.1 However, precursor lesions are often tiny and easy to overlook.

TXI technology aims to enhance the visibility of potentially suspicious tissue, which includes inflammations, flat or depressed lesions, using a white-light imaging effect that improves the color, structure and brightness.

By supporting better visibility of potential lesions, TXI aims to contribute to higher detection rates.

    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.

NBI: The Power of Accurate Diagnosis

Narrow Band Imaging (NBI)

Accurate optical diagnosis is important when assessing lesions to determine potential histology, confirm the lateral extent, and thereby guide therapy decisions and suitable patient surveillance intervals.

NBI is a powerful and proven optical technology that allows for a reliable optical diagnosis of major indications in the gastrointestinal tract.1-8

Efficient lesion management strategies that are empowered by NBI include:

  • Targeted biopsies in the upper gastrointestinal tract.2,5
  • Easier decision-making for suitable endoscopic resection techniques4,5.
  • Potentially avoiding histological assessment of low-risk lesions6-8
    (e.g. diminutive rectosigmoid polyps under the resect and discard paradigm).

    Narrow Band Imaging

    Utilizing specific blue and green wavelengths absorbed by hemoglobin, NBI creates a strong contrast between vessels and surrounding mucosa.9 This facilitates the visibility of highly vascularized areas, blood vessel patterns and surface structures that are predictive for distinct histopathologies.10-13

RDI: The Safeguard for Endoscopic Therapy

Red Dichromatic Imaging (RDI)

Gastrointestinal bleeding is a serious challenge, involving considerable mortality of 5-15% and high management costs.
1,2 Consequently, prevention of complications is crucial.

RDI is designed to enhance the visibility of deep blood vessels and bleeding sources.

Developed to facilitate fast, accurate identification and localization of bleeding sites, RDI may help perform speedier, more reliable hemostasis with the aim of reducing stress on physicians.

    Red Dichromatic Imaging

    RDI works by employing specific green, amber and red wavelengths. The latter two penetrate deep into the mucosa, enabling the visualization of deep blood vessels. In case of acute bleeding, RDI increases the contrast between highly concentrated and diluted blood, thereby clearly visualizing the bleeding point.

  • A Unified Platform with
    Broad Compatibility

    One dedicated platform: EVIS X1 merges the two worlds of EVIS EXERA III and EVIS LUCERA ELITE into one —resulting in a vastly extended portfolio of compatible endoscopes.

  • Ready for the Future:
    Artificial Intelligence (AI)

    In the field of AI, we recognize the power to elevate endoscopic imaging to uncharted levels. The next upcoming feature of the EVIS X1 system will be computer-aided diagnosis (CAD) using artificial intelligence.

Additional Features and Technologies

EVIS X1 provides diagnostic and therapeutic innovation alongside proven technologies to improve endoscopic procedures and endoscope handling.

  • 5 LED Spectrum Technology

    The EVIS X1 Video System Center contains five LEDs that are combined to produce different observation modes. It includes an Olympus tailored amber LED enabling the visualization capabilities of the RDI mode. LEDs have a longer life span than other light sources while consuming less energy.

  • BAI-MAC — Improved Image Quality

    BAI-MAC (Brightness Adjustment Imaging with MAintenance of Contrast) is a new image processing technique to improve the brightness levels in dark areas of the endoscopic image, whilst maintaining the brightness of lighter areas to increase the distance view.

  • Touch Panel

    The EVIS X1 Video System Center is operated from a touch panel on the front of the unit, allowing the user to initiate all procedures and settings and control the image data from one device.

  • Pre-Freeze Function — Updated Algorithm

    Pre-freeze analyzes previous images to obtain a clear visual record of the procedure in the shortest possible time (this is an updated algorithm compared to the EVIS EXERA III / EVIS LUCERA ELITE systems).
