In the current era of rapidly advancing medical imaging technology, endoscopic technology, as the "third eye" of doctors, has demonstrated indispensable value in the early detection and precise treatment of diseases. On May 27th, Olympus Corporation received good news that its EZ1500 series endoscope, with its innovative Extended Depth of Field (EDOF) technology, has successfully won certification from the US FDA. This breakthrough marks a new chapter in endoscopic imaging technology.


❒ Olympus Innovative Technology

Olympus' EDOF technology achieves depth of field expansion through beam splitting, improving the quality of endoscopic imaging. Olympus' latest EDOF extended depth of field technology has played a revolutionary role in the field of endoscopic imaging. This technology cleverly uses two prisms to accurately split the light entering the lens into two beams, focusing on the near and far images respectively. These two beams of light are perfectly fused on the image sensor, presenting a wide depth of field, clear and delicate image.


In terms of imaging technology, EDOF ™ Compared to traditional endoscopes, technology has demonstrated excellent image clarity and detail capture capabilities. Especially in the observation of gastrointestinal mucosa, this technique can clearly present the entire lesion area, significantly improving the detection rate of lesions. Compared to the previous generation of Olympus endoscopes, EDOF ™ Technology provides better visibility and less blurring.


❒ EVIS X1 ™ Advantages of the system

The EVIS X1 system combines various technologies such as TXI, RDI, NBI, etc. to improve the efficiency and diagnostic accuracy of endoscopic examination. EVIS X1 ™ As a highly advanced medical imaging system, the system integrates numerous innovative technologies aimed at enhancing the detection, diagnosis, and treatment capabilities of gastrointestinal diseases. In addition to the latest depth of field extension technology, the system also offers multiple advanced imaging modes.


TXI technology improves the detection rate of adenomas, reduces the risk of cancer, and achieves more accurate detection of lesions. By enhancing the color and texture of images, this technology significantly improves the visibility of lesions and polyps. Its latest randomized controlled trial has confirmed that it can increase the adenoma detection rate (ADR) by 13.6%.


RDI improves vascular visibility and NBI enhances mucosal observation, both of which provide support for early cancer detection. Through red dual color imaging, RDI technology effectively enhances the visibility of deep blood vessels and bleeding points. Simultaneous Narrowband Imaging (NBI) enhances visual observation of mucosal and vascular patterns through the application of specific blue-green wavelengths. The combined application of these technologies has transformed endoscopy from a single "observation tool" to an efficient "auxiliary diagnostic platform".


❒ The Development of Endoscopy Industry

The competition in the domestic endoscope market is fierce, gradually breaking the monopoly of foreign brands and increasing market share. With the continuous development of electronic endoscopic technology, the market landscape is also gradually changing. At present, Japanese companies dominate the electronic endoscope market, but domestic companies are gradually rising and have a significant impact on the market landscape. Especially since the exposure of hygiene hazards in Olympus reusable endoscopes in 2015, the domestic disposable endoscope market has experienced rapid growth.


Chinese enterprises have made breakthroughs in key technological fields, promoting the transformation of the endoscope industry into a full chain medical platform. Many domestic companies such as OFILM have launched a disposable endoscope module with a diameter of only 5mm through cross-border innovation, which has significantly reduced its cost compared to imported products. The competition between industries will increasingly focus on multiple aspects such as technology integration, cost control, and localized services. Looking ahead to the future, Chinese companies' breakthroughs in core technologies such as optical modules and image processing chips, as well as their precise grasp of policy dividends and market demand, are gradually transforming them from "substitutes" to "rule makers".
