XVISION
-S
PINE
Components
The
XVISION
-S
PINE
(
XVS
) system is comprised of the following main components.
4.1. XVS Software
The dedicated
XVS S
OFTWARE
receives the intraoperative 3D scanner images and calculates
the registration between the patient’s anatomy and the acquired intraoperative images. It also
creates a 3D scanned spine model and initializes the
H
EADSET
.
It then receives tracking information calculated by the infrared (IR)
H
EADSET
camera and
displays tracked virtual images of the surgical instrument aligned with the patient on the
computer monitor. These virtual images are of a 3D model and axial and sagittal 2D views.
The
H
EADSET
displays the same virtual images with the 3D model aligned with the patient.
The computer running the
XVS S
OFTWARE
is connected to the
H
EADSET
by WiFi.
Dedicated menus of the user interface are accessed either with a touch screen or a mouse and
keyboard.
4.2. Router
The router is used to support wireless communication between the computer on which the
XVS S
OFTWARE
is installed.
4.3. Headset
The
H
EADSET
is comprised of an infrared tracking camera, infrared illumination, optical
transparent near eye displays and two optional LCDs for partial occlusion of the scene.
Note:
During the surgical procedure the
H
EADSET
should remain between 30 cm and
70 cm above the tracked instruments.
