A modular video streaming method for surgical assistance in operating room networks

Area of Science:

• Medical Informatics
• Digital Imaging
• Surgical Technology

Background:

• Continuous video is increasingly vital for minimally invasive surgery.
• Operating room (OR) video communication demands device interoperability, efficient data transfer, and robust IT infrastructure.

Purpose of the Study:

• To develop and test a digital video communication framework for ORs.
• To ensure functional and semantic interoperability among imaging modalities.
• To provide an economical alternative to dedicated integrated OR solutions.

Main Methods:

• A two-channel client-server architecture was implemented for stream and data handling.
• A video stream description (VSD) specification was defined for negotiating stream characteristics.
• The Structural Similarity (SSIM) Index was used for quality assessment of streamed data.

Main Results:

• Two prototype applications were developed and tested on a dedicated OR network.
• Acceptable network performance was demonstrated for streaming video under clinically realistic conditions.
• The framework proved feasible for OR video data communication.

Conclusions:

• A novel OR video communication framework was successfully developed.
• The framework leverages existing OR network infrastructure for cost-effectiveness.
• It provides essential interoperability for continuous video data in surgical procedures.
