Overview
How The Stealth System Works
The Stealth System is made up of three charge-coupled device (CCD) cameras, a computer workstation, a dynamic reference frame (DRF), and a handheld stereotactic device. The DRF and pointing device contain infrared LEDs, which the cameras track as to accurately update the position of the probe and patient anatomy.[1]In other words, the Stealth System works to create a translation map between all points in the patient images and the corresponding points on the patient anatomy.[2]Once this map is established, when a point on the patient is touched with the probe, the computer will calculate where that same point is on the patient scans.
Real Time Tracking
Because things tend to move around in an operating room, the system has to be able to track movements in real time. To accomplish this, a patient reference frame is created by a combination of an optical reference frame (ORF) and and AXIEM™ reference frame.[2]The ORF is a series of optical markers mounted on a metal frame, and the AXIEM™ reference frame is lots of embedded sensing coils housed in plastic, and both of these sit in rigid positions in respect to patient anatomy.[2]The ORF contains either LEDs or light reflecting sterile spheres. The camera array triangulates the position of these markers and send this information to the computer constantly, thus updating the position of the patient constantly.

Significance
The Stealth System is important because it is a fascinating application of multiple types of technology in an all-in-one system. Stealth demonstrates the capabilities of computer technology in a medical field and that it can make a difference in the lives of people everywhere.
