4 DISCUSSIONS AND CONCLUSION
In this paper, we presented a study of the usage of AR/VR visualization within 100 acquisitions of the novel Freehand SPECT imaging within real operating rooms. This is one of the first intra-operative devices, which makes full use of AR as well as VR visualization. Our analysis of the choice of user interface, mainly confirms the importance of the analysis of the surgical workflow and the need for adoption of the user interface and visualization hardware and software to particular flow of subtasks within a surgical procedure. For each phase of the procedure, e.g. pre-incision or post-excision imaging, the OR team tends to prefer a particular mode of visualization. For some subtasks, e.g. setting proper threshold values for the reconstruction, AR has been the preferred visualization mode, while for other subtasks, e.g. image-guided resection of the lymph node, the preference goes to VR.
