Architecture for Augmented Reality Guidance Applications Using DICOM-RTV

Abstract

The recently published DICOM-Real Time Video (DICOM-RTV) standard allows real-time synchronization of transported video and medical metadata flows. In order to demonstrate the advantages of this synchronization by design, a demonstration of a DICOM-RTV Augmented Reality (AR) based solution is proposed. This solution consists in facilitating the surgeon's gesture by monitoring the positioning of the biopsy needle under ultrasound guidance and constructing virtual and augmented reality views of the needle's trajectory. In this paper, the platform architecture and the obtained results are presented. Furthermore, a comparison between our proposed solution and a setup that do not use DICOM-RTV is provided in order to show the difference in term of precision, synchronization and delay. The obtained results validate the contribution of real-time synchronization to improve the accuracy of surgical gesture aid applications such as AR.
