a camera configured to be optically tracked and to obtain images of at least one surgical instrument located within the body form;
a computer configured to receive signals from the optical tracking system; and
a display operatively coupled to the computer and operative to display the images of at least one surgical instrument and a virtual background, the virtual background depicting a portion of a body cavity, the virtual background displayed from a perspective of the camera configured to be optically tracked.
2 . The surgical training device of claim 1 , wherein the images of the at least one surgical instrument are from a perspective of the camera configured to be optically tracked.
3 . The surgical training device of claim 1 , wherein the images of the at least one surgical instrument are virtual images.
4 . The surgical training device of claim 1 , wherein the images of the at least one surgical instrument are live video images.
5 . The surgical training device of claim 1 , wherein the camera configured to be optically tracked is operative within the body form for up to six degrees of freedom.
6 . The surgical training device of claim 1 , wherein the images of the virtual background are continual throughout at least one degree of freedom of movement of the camera configured to be optically tracked.
7 . The surgical training device of claim 1 , wherein the images of the virtual background are continual throughout six degrees of freedom of movement of the camera configured to be optically tracked.
8 . The surgical training device of claim 1 , wherein the computer is configured to generate one or more performance metrics.
9 . The surgical training device of claim 8 , wherein the display is operative to display the one or more performance metrics with at least one image of at least one surgical instrument.
10 . The surgical training device of claim 1 , wherein the computer is configured to compare the position and alignment data of the camera configured to be optically tracked with at least one digitally stored model of a camera.
11 . A method of surgical training, comprising:
obtaining image data of at least one surgical instrument from a camera located within a body form;
optically tracking the camera;
transmitting signals corresponding to position and alignment information of the camera;
receiving the signals in a computer;
displaying the image data of the least one surgical instrument; and
displaying from a perspective of the camera a virtual background, the virtual background depicting a portion of a body cavity.
12 . The method of claim 11 , wherein displaying the image data of the least one surgical instrument includes displaying from a perspective of the camera.
13 . The method of claim 11 , wherein displaying the image data of the at least one surgical instrument includes displaying a virtual image.
