This device is called the Guided Surgical X-ray Glasses. It would be used for surgery and be able to guide the surgeon and show them what is wrong so they know exactly where to make the incision for the best results possible. It would do this with guiding lasers and being able to let the surgeon see the organ or bone.This device would help on mars by increasing the amount of success during surgery on mars. We could adjust the frames to every astronaut’s head and due to blood which causes swelling we could print them new frames to make sure they fit. Most of it can be made from current technology we use live x-ray to scan luggage why not use it for surgery the only problem which would need future technology would be to contain the radiation exposure. In worse case scenario it could be used to self diagnosis an injury to see what's wrong so you would know exactly what to do to increases chances of survival.
