Newly Developed “High-resolution 3D System”
will Ease Eyestrain among Surgeons
— Physicians performing endoscopic surgery will welcome
a more natural three-dimensional view when suturing and other procedures are required —
Olympus Medical Systems Corporation (President: Kouji Miyata) has developed a new “High-resolution 3D system” with compact display and new endoscope optical systems designed to minimize image distortion. The new system was developed in response to surgeons’ concerns about eyestrain experienced when using existing 3D endoscopes. Olympus Medical Systems plans to conduct further research to verify this technology.
The new “High-resolution 3D System” utilizes Olympus’s advanced technology in the areas of endoscopes and surgical microscopes.
It consists of the following elements:
(1) 3D display and balance arm
(2) 3D endoscope and holding arm
(3) 2D monitor for assistant
(4) 3D display stand (containing controller)

Project Background
Today, endoscopic surgery is used to treat many conditions requiring delicate procedures, such as radical prostatectomy and coronary artery bypass grafting. Some facilities in Europe and North America employ special surgical robots that are combined with 3D endoscopes as standard equipment. In Japan, the development of 3D endoscopes for endoscopic surgery began around 1992, and Olympus released a system with specially designed spectacles in 1996. There are several types of 3D endoscopes. Some require the use of LCD shutter spectacles or polarized spectacles, while others allow the surgeon to view 3D images on a monitor without the need for special spectacles. However, surgeons have complained of eyestrain experienced when looking through these systems, and so the systems are still not widely used. The eyestrain appears to result from unnatural eye movements that occur when viewing images in ways that are different from natural observation with the naked eye. Possible reasons include a) significant differences between the images viewed with each eye, including variations in size, resolution, brightness and color, and other distortions, and b) left-right “crosstalk,” where the image seen by the left eye is also visible to the right, and vice versa.
Components of the newly developed High-resolution 3D System include a bright, crosstalk-free display device, an endoscope that can be switched between 3D and wide-angle 2D viewing, and a balance arm that can be positioned to suit any viewing position. It also features a new optical system designed to provide more natural 3D images.
Olympus Medical Systems will continue to contribute to the advancement of medicine by providing medical professionals and hospitals with safe, dependable and highly efficient medical tools for use in minimally invasive diagnostic procedures. Its aim is to optimize efficiency and contribute to the early detection and treatment of disease by supplying high-quality, high-performance products and services to support patient-friendly medicine.
Features of the High-resolution 3D System
(1)Optical system designed to reduce eyestrain
The 3D imaging system has two compact high-resolution displays (6-inch SXGA LCD monitors with 1,280 x 1,024 resolution). Crosstalk, which is thought to cause eyestrain, is eliminated, since the left and right displays are viewed independently. When linked to a 3D endoscope equipped with a low-distortion optical system, this system reduces left-right image variation and provides 3D images that look more natural.

(2)Designed for Ease of Use
The balance arm and holding arm allow the 3D display and 3D endoscope to be moved freely to suit the viewing position of the surgeon.
(3)3D Endoscope Switchable between 3D and Wide-Angle 2D
The endoscope can be switched between 3D and wide-angle 2D as required. The 3D view is ideal for delicate procedures requiring a sense of depth, such as suturing, while the 2D view is effective for checking orientation, such as the relative positions of the surgery site and the forceps. To achieve this performance, priority was given to high-quality, distortion-free images in the design of the 3D optical system, while the 2D optical system was designed to support wide-angle observation.
