Abstract
A radiolucent pressure-sensing mattress for a surgical table includes radiolucent pressure sensors, and a radiolucent electromagnetic interference shielding layer. The radiolucent pressure sensors measure the amount of force exerted by a patient's body at certain locations of the radiolucent pressure-sensing mattress. The radiolucent electromagnetic interference shielding layer envelopes the radiolucent pressure sensors. The shielding layer shields the sensors from electromagnetic interference from other sources in an operating room. In certain embodiments, the shielding layer is made from woven carbon fiber.
