A mobile and navigated image viewer for surgery--evaluation of precision

Area of Science:

• Medical Imaging
• Computer Vision
• Surgical Navigation

Background:

• Current medical imaging visualization relies on fixed displays, limiting in-situ use.
• Mobile viewing devices offer potential for enhanced intraoperative guidance.
• Accurate overlay of imaging data onto the patient view is crucial for navigation.

Purpose of the Study:

• To introduce NaviView, an ultra-compact mobile device for in-situ medical imaging display.
• To evaluate the overlay precision of NaviView when integrating live video and computed tomography (CT) data.
• To assess the feasibility of using mobile devices for real-time medical image visualization.

Main Methods:

• Development of NaviView, incorporating an optical tracking system for patient and device positioning.
• Integration of medical imaging data (CT) with live video feed.
• Experimental evaluation of the overlay precision between live video and CT modalities.

Main Results:

• NaviView successfully displayed medical imaging data in situ on a mobile device.
• The optical tracking system enabled proportionable display of imaging data.
• Experiments quantified the overlay precision between visualized live video and CT data.

Conclusions:

• NaviView represents a novel approach to in-situ medical imaging visualization.
• The device's tracking system facilitates accurate data overlay.
• Further research can explore NaviView's application in various surgical and diagnostic procedures.
