I love coffee and I love this concept.
Take a look:
Engineers at Vanderbilt University have developed a silicon cap filled with coffee grounds to track patient head movements and orientation during delicate nose and throat surgery. The technology was recently presented at the International Conference on Information Processing in Computer-Assisted Interventions in Barcelona, Spain.
At present, patients undergoing nose and throat surgery wear a basic elastic headband studded with reflective dots that can be picked up by sophisticated tracking systems, allowing surgical systems to track where the tools are oriented inside the patient. “These are very delicate operations and a sophisticated image guidance system has been developed to help the surgeons, but they don’t trust the system because sometimes it is spot on and other times it is off the mark,” said Robert Webster, Associate Professor of Mechanical Engineering and Otolaryngology at Vanderbilt. The problem with the current system is that surgeons can inadvertently move or knock the headband so that it slips out of position on the patient’s head, throwing out their measurements.
