Device and method for displaying a geometrical figure on the body surface of a patient

摘要

Device for representing a geometric figure on the surface of a body of a patient on a support, comprising: - at least one projection device (6) through which can project a geometric figure predetermined on the three-dimensional surface patient body (3), - at least one control device (5) and at least one device of optical sensors (20), through which you can register the geometric projected figure on the surface of the patient's body (3) and you can provide recorded data to the control device (5), wherein the control device (5) is configured to determine the three dimensional coordinates of the geometrical figure projected onto the patient's body from the data collected by the device sensors (20), - and wherein the control device (5) is formed to compare the three dimensional coordinates obtained from figure GEOMET rich projected onto the patient with a nominal three-dimensional coordinates.
