EVIS LUCERA Gastrointestinal Videoscope
Olympus Optical Co., Ltd. ( President: Tsuyoshi Kikukawa ) is pleased to announce the launch of the EVIS LUCERA range of endoscopic video information systems, the latest advance for improving the accuracy of endoscopic analysis, an indispensable minimally-invasive technique for the early diagnosis and treatment of gastrointestinal disorders. As the world's first high-definition endoscopic video systems, the new EVIS LUCERA systems provide visibly higher image quality. They also feature innovative functions for the enhancement of minute variations in mucosal tissue color ( Adaptive IHb Color Enhancement*1 ) and for the enhancement of mucosal tissue surface detail and texture ( Structure Enhancement*2 ). The EVIS LUCERA range will go on sale in Japan with the principal target market comprising hospitals and clinics. In due course, Olympus plans to make the product range available in overseas markets*3 ( U.K., China, S. Korea, Taiwan, Singapore, and elsewhere ).
*1:  IHb = Index of Hemoglobin: a measure of the concentration of hemoglobin in mucosal tissue based on an index IHb = 32•Log2( R/B ). The adaptive IHb color enhancement function works by calculating the average hemoglobin concentration of the tissue, and then displaying those areas with higher-than-average IHb values using more red, and areas with lower-than-average IHb values with more white. The potential utility of this function derives from current medical opinion that tissue lesions tend to be tinged red due to the higher rate of blood flow that results from heightened cell activity in affected areas.
*2:  The structure enhancement function uses electronic processing to enhance the detail and texture of the image by exaggerating the appearance and contours of tissue surfaces.
*3:  Regulatory/medical approval will be sought in accordance with local regulations.
EVIS LUCERA endoscopic video information systems will be exhibited at the upcoming 64th General Meeting of the Japan Gastroenterological Endoscopy Society (president: Prof. Hiromitsu Saisho, Dept. of Oncology, Chiba University Graduate School of Medicine), which is due to be held at the Pacifico Yokohama convention center October 24-27.
Main Features
1. World's first high-definition ( HDTV ) endoscopic video information system
2. Supports more accurate diagnosis of subtle changes in tissue pathology
3. New range of scopes offers either a smaller outer diameter or higher image quality.
4. Functions designed to relieve patient stress, boost operator convenience, and improve examination efficiency
5. Supports medical data networking for increased management and system administration efficiency
Product Background
As key medical instruments for detecting pathological changes early and with a minimum of patient discomfort and stress, endoscopes make a significant contribution to human health through their widespread use in the diagnosis and treatment of gastrointestinal disease. In Japan in recent years, increasing Westernization of the Japanese diet and other lifestyle factors have resulted in a marked rise in colon cancer morbidity. However, only about 63% of those who test positive in the mass fecal hemoccult screening tests routinely conducted by Japanese regional authorities subsequently undergo further testing, and of this number only about 30% elect colonoscopy.

In addition, nationwide efforts to reduce medical spending and improve medical risk management have caused practitioners to focus on higher management efficiency and the elimination of diagnostic errors. Financial pressures have also led to the introduction of networked patient information and accounting systems for more efficient management, and have increased demand for diagnostic equipment that can be integrated into such networked environments.

As a leader in the field of endoscopy, the mission of Olympus is to contribute to the health of people everywhere, and to respond to the changing needs of the times. To this end it has developed the new EVIS LUCERA range of endoscopic video information systems, its first full model upgrade of the range in five years, to provide more accurate diagnostic capabilities that are less invasive for patients and easier for physicians and medical personnel to use.
Details of Main Features
1. World's first high-definition ( HDTV ) endoscopic video information system
The new EVIS LUCERA HDTV-compatible endoscopic video information systems can deliver far more realistic images of fine capillary and mucosal tissue surface conditions than are possible with conventional video systems, thereby providing support for more accurate diagnoses.

2. Supports more accurate diagnosis of subtle changes in tissue pathology
To avoid minute changes in pathology being overlooked, endoscopy technicians typically look for anomalies in mucosal tissue coloration and surface details. The new EVIS LUCERA endoscopic system boosts the diagnostic value of video images through chromatic enhancement of minute differences in tissue color based on an analysis of differences in the mucosal index of hemoglobin, as well as enhancement of mucosal tissue surface detail and texture. This combination of functions may help to boost diagnostic accuracy significantly.

3. New range of scopes offers either a smaller outer diameter or higher image quality.
To help minimize patient discomfort, the new range of EVIS LUCERA scopes includes the GIF TYPE XP260 SlimSIGHTTM ultra slim scope for upper gastrointestinal tract examination. With a distal end outer diameter of just 5mm including the fitted air/water nozzle, the new scope offers operating ease that is comparable to standard 9mm models.
The new range of scopes includes three models for upper digestive tract procedures and four models for colonic procedures. When compared with previous systems, they offer either: a) comparable image quality from a scope with a smaller outer diameter, or b) superior image quality from a scope with the same distal end outer diameters.
All of the colonovideoscopes in the new range feature the variable stiffness function (=independent manual adjustment of insertion tube flexibility), a user-acclaimed design improvement that may reduce patient discomfort by making tube insertion easier for operators to perform.

4. Functions designed to relieve patient stress, boost operating ease, and improve diagnostic efficiency
A special image optimization function is built into the system so that, when the button is pressed to operate the shutter, the best image is automatically selected from the video recordings made during that part of the procedure. As a result, the number of still re-takes may be reduced, making examinations a faster and smoother process.
When using the high-resolution LCD monitor, up to four of the immediately preceding images can be simultaneously displayed, further reducing the likelihood of missed or duplicate images.
Compared to the EVIS 240 videoscope system, the width of the main unit has been reduced by 14cm, allowing greater freedom in system placement. In addition, the front of the system trolley is now equipped with a large handle to make the unit easier to move.

5. Supports medical institution computer networking for improved management and systems administration efficiency
A new memory chip allows users to keep a record of scope use and other essential information. It also allows the scope to be linked to the newly introduced Solemio ENDO Endoscopy Support System for digital image storage, operational history electronic recordkeeping (including possible cleaning and disinfection recordkeeping in the future), and bi-directional data exchange with medical institution accounting systems for improved diagnostic equipment management efficiency. As a result, an EVIS LUCERA system can significantly aid the process of endoscopic department computerization, and assist in the pressing task of reducing medical costs and diagnostic errors by promoting improved management and data systems administration efficiency.
