Ergonomics for image-guided procedures can be improved by using mixed reality headsets. Such headsets offer the ability to position holographic monitors that display information, such as an ultrasound stream, within the operator’s field of view during procedures. However, one of the barriers of clinical adoption of mixed reality headsets is high latency of information projected on to the headset. Upwards of 40% of the overall latency of the entire system can be due to video cards that capture procedural imaging for wireless streaming. The costs of the video cards can vary widely, from as low as $20 to upwards of several hundreds of dollars. The latencies of four separate video cards with a range of costs were evaluated. Based on these results, we propose an ideal tradeoff between latency and costs for clinical use of wirelessly mirroring procedural imaging into mixed reality headsets.
