| Abstract: | This thesis explores the implementation of remote real-time 3D viewing technology for supervision and education applications in endoscopy and remote viewing via camera-equipped glasses. Stereoscopic imaging is important in surgeries where precision is required. This project builds on existing technologies for using 3D in operating rooms, such as remote viewing via an operating microscope at Deventer Hospital. Humans are able to see 3D because each eye sees a different part of the world. The brain combines these two images into a single image in which depth can be perceived. This is called stereoscopy. Using two cameras, the surgical field is recorded from different angles to get a stereoscopic image. In this project, this is done with an endoscope and camera-equipped glasses. The two images are brought in via software programs on the laptop and pasted next to each other to get a side-by-side view. This image is then streamed to a phone placed in a VR headset. This allows live viewing during operations to give advise or learn from it. The thesis covers the technical implementation, required hardware and software and the additional challenges, both technical, ethical and legal. Technical challenges include latency, image quality maintenance and camera alignment. Ethical and legal challenges include compliance with various laws and regulations that need to be adhered to. These include the GDPR to protect personal data and the MDR to ensure the safety of medical devices. In addition, tests were done to validate the performance of the systems. Test rigs were built for both the endoscope and the camera-equipped glasses. Resolution, colour accuracy, depth of field, image distortion, latency and depth perception were tested according to predetermined program requirements. The results showed that the glasses scored well on image distortion and latency, but less on resolution, colour accuracy and depth perception. The endoscope performed well on resolution, depth of field, image distortion and depth perception, but lower on colour and latency. It also places the results in clinical context and suggests possible points for improvement and future perspectives including possible follow-up studies. |
