1. A method for generating a display of an image of a patient's internal anatomy in a surgical field during a medical procedure, comprising: acquiring an image of the surgical field with the imaging device in a first orientation; displaying the acquired image; moving the imaging device, patient, or table from the first orientation; tracking the movement of the imaging device, patient, or table from the first orientation; moving the displayed image in relation to the tracked movement prior to acquiring a new image of the surgical field with the imaging device; wherein the step of moving the displayed image includes compensating for errors in the movement of the displayed image generated by the position of the imaging device relative to the surgical field; wherein the step of compensating for errors includes determining the center of mass for the surgical field and adjusting the movement of the displayed image based on the position of the imaging device relative to the center of mass.
