Recent developments in medical imaging technology let doctors see inside patients in realtime without having to conduct invasive probes with cameras on the end of wires. Unlike with x-rays they can use thermal imaging to produce a 3-D active map of a patient's flesh, not just snapshots of their skeleton. They can even track the progress of individual cells through the body. Dr McNider found that this technology was brilliant, especially when combined with a VR headset which let him work while looking at the patient rather than having to study a flat monitor and try to relate it to the body under his hands.
