Smart Glasses Systems for Supplying Surgery Assist Image

Korea University Background
It is necessary to improve inconvenience and inaccuracy when an operating surgeon monitors the existing images of the affected area.
To display images of surgical areas on monitors installed in the existing operating rooms is inconvenient since an operating surgeon should alternately keep an eye on the monitor and the patient’s surgical area.
The method of showing on transparent displays in the form of existing eyeglasses worn by an operating surgeon has a disadvantage that the wound imaging cannot be exactly matched the actual images since it cannot reflect the movement of the patient in case of detecting the movement of the operating surgeon.
Technology Overview
Near-infrared taking module:
The color fluorescent markers are placed around the patient’s surgical area, and filmed by near-infrared camera module and then the near-infrared fluorescence imaging is transmitted to the image processing module.
Image processing module:
Generating real-time conversion fluorescence images by converting the near-infrared fluorescence imaging in real time into either the direction or size of taking of the visible light image based on the visible light image so the movement of the operating surgeon is reflected in the near-infrared fluorescence imaging.
Smart glass:
Real-time conversion fluorescence images displayed on the transparent display unit in the operating surgeon’s view are overlapped to provide visual effects that fluorescent material appears to be displayed on the patient’s surgical area monitored by the operating surgeon
Reflecting the movement of the operating surgeon on the near-infrared fluorescence imaging:
Providing real-time conversion images by converting the near-infrared fluorescence imaging in real time into either the direction or size of taking of the visible light image.
Overlapping real-time conversion images displayed on the transparent display unit in the operating surgeons view.
Benefits
Providing a convenience of surgery of operating surgeon:

The operating surgeon can perform a surgery while visually observing in real time.

Improving an accuracy of surgery of operating surgeon:

Real-time conversion images displayed on the transparent display unit in the operating surgeon’s view are overlapped to provide visual effects that fluorescent material appears to be displayed on the patient’s surgical area monitored by the operating surgeon.
The near-infrared fluorescence imaging provide an effect that appears to be displayed in the actual surgical area of the patient.

Applications
This technology can be used in various fields that require visual functions such as manufacturing industry, camera, VR industry, AR industry, etc., as well as medical industries such as surgery, medical treatment, diagnosis, etc.
The global market for medical displays is expected to reach from $1.7 billion in 2016 to $2.47 billion at an annual average growth rate of 4.8percent by 2024.
Recently, the Ministry of Food and Drug Safety announced “guidelines of approval and examination for medical devices applied virtual reality(VR)and augmented reality (AR) technologies.
In addition, in the field of VR/AR, the smart glass market, which is worth about $327 million in 2016, is expected to grow to $9 billion by 2020.
Opportunity
– Tested in intended environment.
