Abstract
A surgical simulator is described, comprising a physical model (M) of at least one anatomical structure (L, G) which includes at least one model of a deformable tubular duct (AT; B) and comprises, in combination:- a recording device (C) arranged to acquire images (IS) of a background scene that includes the model (M) of an anatomical structure;- a plurality of electromagnetic position sensors (S1-S4) associated with predetermined portions of the tubular duct model (AT; B), each of the sensors being arranged to make available, in response to an electromagnetic excitation field, an electrical location signal indicative of the position and orientation of the associated portion of the tubular duct model (AT; B);- a processing unit (X) adapted to acquire image data (IS) representing the background scene and location data (UP) of the portions of the tubular duct model (AT; B) with which the plurality of sensors (S1-S4) is associated; and- a display device (D) adapted to represent complex images (I') of an augmented reality scene, including images (IS) of the background scene and additional images (IA) superimposed on the images (IS) of the background scene, generated by the processing unit (X) and representing the portions of the tubular duct model (AT; B).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
