First, a patient undergoes CT scans with the preinstalled Medgital registration frame. This is necessary to further bind the hologram to the patient.
Next, according to CT data, the doctor performs segmentation (selection) of the necessary anatomy elements for visualization in mixed reality glasses. In addition he adjusts the method of binding the hologram to the patient.
After that, the doctor marks the access point and additional landmarks for further navigation.
In the beginning of the operation, the sterilized registration frame is installed on the patient again. The mixed reality glasses are put on the surgeon and finally, according to the hologram, he performs the procedure.
