Mixed Reality Surgical Navigation Method
The aim of the study is to present the features of our own new mixed reality surgical navigation method. The paper describes the workflow from the stage of preoperative patient scanning to postoperative patient scanning. Potential sources of positioning errors are identified, design and software approaches to reduce their impact are described: the implementation of the unity of the location of markers, the execution of markers. The applied approach for estimating the cumulative positioning error is described. As a result of the implementation of these approaches in practice, the value of the total navigation error was less than 2 mm, and more than 80 successful operations were performed in this way. This value of navigation error is sufficient for most surgical operations, but is unacceptable in neurosurgery. The study can be useful for improving similar systems, as well as for designing mixed reality systems in other scientific fields.
