Query: Surgical navigation systems based on augmented reality technologies   This study considers modern surgical navigation systems based on augmented
reality technologies. Augmented reality glasses are used to construct holograms
of the patient's organs from MRI and CT data, subsequently transmitted to the
glasses. This, in addition to seeing the actual patient, the surgeon gains
visualization inside the patient's body (bones, soft tissues, blood vessels,
etc.). The solutions developed at Peter the Great St. Petersburg Polytechnic
University allow reducing the invasiveness of the procedure and preserving
healthy tissues. This also improves the navigation process, making it easier to
estimate the location and size of the tumor to be removed. We describe the
application of developed systems to different types of surgical operations
(removal of a malignant brain tumor, removal of a cyst of the cervical spine).
We consider the specifics of novel navigation systems designed for anesthesia,
for endoscopic operations. Furthermore, we discuss the construction of novel
visualization systems for ultrasound machines. Our findings indicate that the
technologies proposed show potential for telemedicine.
