To ensure high clinical quality and equitable patient access, we aim to unify expertise in a virtual MR-linac center within the same geographical region. Material/Methods: In 2024, specialists from two institutions jointly presented the vision for a virtual MR-linac collaboration to the management of the radiotherapy departments. The short-term vision enables physicians and physicists from one institution to carry out adaptive and non-adaptive treatments through remote access to the treatment planning and delivery systems at the other institution. Collaboration between on-site treatment personnel and the remote physician and physicist is conducted through a video meeting. The long-term goal is to establish a fully integrated patient pathway with shared clinical and technical resources in a virtual setup. Results: Between February and April 2025, working groups focused on establishing common ground for the treatment pathway, and three non-adaptive treatments of patients with liver targets were successfully completed remotely. In June 2025, 23 representatives met for a one-day workshop to discuss visions for a fully integrated virtual center. Since July, six patients have received remote adaptive treatment, and three patients have received remote non-adaptive treatment. Target locations that have been treated remotely include the kidney, liver, and pancreas. All treatments were performed successfully, with no lag in the remote connection and within standard appointment slots. The experience gained is evaluated and refined through weekly multidisciplinary meetings as we move forward and expand indications for the virtual workflow, including to central lung. Conclusion: The virtual MR-linac center represents an innovative model for modern healthcare workflows, providing solutions to future challenges such as recruitment and financial constraints. It ensures efficient utilization of high-cost, high-technology resources while maintaining high standards of patient care. Future work includes harmonization of planning and adaptive procedures and strengthen collaboration as one unified virtual team. Through sharing this experience, we hope to provide both inspiration and practical information for other centers, and we believe that this can serve as a model for future care in
