Patent Images
1. A method for determining a relative location of at least two trajectories, the method comprising:
- providing image data of a patient in a first plane;
tracking a three-dimensional trajectory of an object;
determining, with a surgical navigation system, a position of a first representation of a first trajectory of the object relative to the provided image data of the patient;
determining, with the surgical navigation system, a position of a second trajectory of the object relative to the image data of the patient; and
storing the first trajectory or the second trajectory.

Abstract
A method and apparatus for determining, calculating, and/or viewing a trajectory. The trajectory can be displayed on a display relative to image data of a patient. A user can use the system to determine relationships between two or more trajectories that have been determined. The relationships can be within two dimensional, three-dimensional, or four dimensional space. The relationships can include distance, angle, etc. The relationships can also be determined between real time trajectories and stored trajectories, or combinations thereof.

24. An apparatus for determining a trajectory of at least one object during a surgical procedure, said apparatus comprising:
-
a tracking system operable to track a three-dimensional position of the object; a computer processor in communication with said tracking system; a memory in communication with said computer processor, said memory storing; image data of a patient; instructions that when executed by said computer processor, track the trajectory of the object, store a first tracked trajectory into memory upon receiving a storage command, generate representations of a second tracked trajectory and the first stored trajectory, and superimpose the representations onto the image data; and a display operable to display the superimposed representations onto the image data. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. An apparatus for storing a trajectory of at least one object during a surgical procedure, said apparatus comprising:
-
a computer processor in communication with a tracking system; a memory system in communication with said computer processor, said memory storing; image data of a patient from at least two planes; and instructions that when executed by said computer processor; track the trajectory of the object, store the trajectory into the memory system upon receiving a storage command, generate representations of the tracked trajectory and the stored trajectory, superimpose the representations onto at least one of the planes of the image data, select a first and a second trajectory, at least one of compute a distance in three-dimensional space between the first and second trajectories, compute an angle between the first and second trajectories, or combinations thereof; and a display in communication with the computer processor operable to display at least one of the superimposed representations, the computed distance, the computed angle onto the image data, or combinations thereof. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)
