8K Endoscope FAQ

  1. Q01.Is the endoscope the same as a gastroscope?

    No. There are two types of endoscopes, “flexible” and “rigid,” and “flexible” endoscopes are what are commonly referred to as “gastroscopes.” The Kairos 8K endoscope is the “rigid” endoscope used in laparoscopic surgeries.

  2. Q02.What is laparoscopic surgery?

    Laparoscopic surgery is a surgical method where one or more small holes are made in the abdominal or chest area, and devices such as a rigid endoscope and forceps are inserted to perform surgery. The doctors conduct the surgery while looking at the images of the body from the rigid endoscope that are displayed on a monitor set up in the operating room.

  3. Q03.Why laparoscopic surgery?

    Compared to laparotomies, the scope of the incision is smaller for laparoscopic surgeries, making the scar from the incision less noticeable and resulting in less physical stress. As the recovery time is short, patients have better chance to be discharged earlier and return to their normal lives.

  4. Q04.What does 8K mean?

    8K means that there are approximately 8000 pixels on the horizontal axis of the monitor. In other words, for a monitor with an aspect ratio of 16:9, it would have 7680 horizontal pixels x 4320 vertical pixels and a resolution of 33 million pixels. Compared to a 2K monitor with 1920 horizontal pixels and 1080 vertical pixels and a resolution of 2 million pixels, 8K has approximately 16 times the resolution.

  5. Q05.You are developing 8K endoscopes, but in the future, won’t it evolve from 8K to 16K to 32K, and your technology will become obsolete?

    No. We believe that 8K technology has a different value from the competition over pixels that took place when moving from 2K to 4K. Based on research conducted up until this point by NHK on human science, there is a saturation point to the amount of immersion and presence that can be experienced within the scope of human sight and field of vision, and we have found that 8K is sufficient. It is thought that 8K (=33 million pixels) efficiently provides the maximum immersion and presence that can be perceived by human sight, and the Kairos 8K endoscope camera was developed based on this design concept rooted in human science.

  6. Q06.Is there really a need for 8K in the medical field?

    Kairos believes that the medical field is moving into an era when it will shift completely from 2K to 8K. The government is also creating policies to adopt 8K, such as holding meetings to consider the medical applications of 8K technologies. In addition to significantly increasing the safety of surgeries overall, 8K images are expected to have various ripple effects such as significantly increasing the standards of diagnoses and education and activating the medical economy.

  7. Q07.Can 8K images taken with the 8K endoscope camera be viewed on my current 4K monitor?

    Yes, they can be viewed on a 4K monitor. However, in order to experience the true quality of 8K, we recommend viewing the images on an 8K monitor.

  8. Q08.Can it zoom?

    Yes. As the pixel sizes for 8K images are extremely small and detailed, one characteristic of the images is that image quality does not decrease even when zooming.

  9. Q09.How will 8K technologies develop in the future?

    In the future, 8K technologies will be made three-dimensional and combined with artificial intelligence and applied to AI diagnosis and will be applied to microscopes for ophthalmic surgeries and neurosurgeries. Data communication networks are being put into place, and in the near future, they will be used to diagnose and treat patients in remote locations.
