Surgeons sometimes leave instruments or sponges inside their patients, typically necessitating a second surgery to retrieve these inadvertent souvenirs. A new system uses portable antennas located around the operating table that read button-size RFID tags attached to the items used in surgery. This automates the tracking process, so that physicians preparing to sew a patient up can be sure nothing’s been left behind.
