| Abstract: | Real-time MR imaging is valuable in monitoring surgical procedures such as biopsies, ablations and radiotherapy. Major challenges during MRI-guided interventions include convoluted scan-plane control and limited scan visibility options inside the MRI room. This project proposes an interactive XR-interface with the MRI scanner as a solution. A proof-of-concept was realised through establishing bidirectional communication between an MRI scanner and XR-HMD via an intermediary PC, using the Siemens Access-i framework. During real-time MR image acquisition, the user can connect to the scanner via Wi-Fi in the holographic environment. Acquired images are shown on a holographic panel, and the user can modify the scan-plane position and orientation using hand gestures. The XR-HMD is MR-safe up to 40 mT. Data transmission latencies of 1.38 ± 0.18 s and 508 ± 194 ms were measured for image and command data, respectively. User test participants were positive about the system and its usefulness in clinical implementations, with ratings of 0.81 ± 0.18 and 0.95 ± 0.11 out of 1.00. Although the current prototype is subject to hardware limitations, it is believed that future XR-interface versions could reduce procedural time, complexity and cost of MRI-guided interventions. |
