Presentation of the six years of experience in using mixed reality applications in planning liver and heart surgery at Oslo University Hospital. Description of research, development and implementation of clinical applications from image data to surgical strategies in 3D. It was initiated by clinicians based on clinical challenges to be fully compatible with clinical reality. Efficient workflow, fully integrated with hospital infrastructures cloud/browser-based with no need for specialized workstations.

Ample experience is derived from surgical planning sessions for colorectal liver cancers and structural heart diseases. Not only limited to the most complex surgical cases. 

In pediatric heart surgery, holographic visualization brings enhanced 3D anatomical understanding of complex heart defects. It provides insight that reduces the risk of damaging critical structures in the surgical area. Holographic information impacts surgical plans in about half of the tested cases.

In liver cancer surgery, holographic visualization brings anatomical overview and improves spatial understanding of internal anatomical structures in relation to the tumour. This is important when planning intricate surgical paths within the liver. Additionally, it better utilizes already available preoperative data to be used in surgical planning as an adjunct to the standard of care.

Industrial collaboration has been vital in the establishment of minimum viable products as well as in establishing a start-up. This paved a path towards regulatory approvals and the distribution of applications for clinical use outside our hospital. 

We will present published and unpublished results from our department - where we have failed and succeeded and what we have learned in the process.

Finally, we will provide a glimpse of the future trend in the current project and what is coming next.
