Abstract:
A surgical instrument navigation system comprising: a computer processor; a tracking sensor for sensing three-dimensional position information of a surgical instrument and transmitting the position information to the computer processor; a memory coupled to the computer processor, the memory including computer instructions that when executed by the computer processor cause the processor to generate an icon representing the surgical instrument positioned in a pre-acquired image of a patient's anatomy, the icon of the surgical instrument including a first portion corresponding to an actual position of the surgical instrument and a second portion corresponding to a projection of the surgical instrument along a line given by a current trajectory of the surgical instrument; and a display coupled to the processor for displaying the generated icon superimposed on the pre-acquired image.
Abstract:
A method and apparatus for percutaneous and/or minimally invasive implantation of a construct. The construct may be implanted using a navigation system for planning and execution of a procedure. A plurality of portions of the construct may be interconnected using locations and paths determined and navigated with the navigation system.
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.
Abstract:
The invention is a system for use during a medical or surgical procedure on a body. The system generates a display from an image data set (106) representing the position of one or more body elements (10, 20, 30; 141; 806; 940) during the procedure based on scans (40) taken of the body. At least some of the body elements are movable with respect to each other. Each scan (40) has a reference for each of the one or more body elements (10, 20, 30; 141; 806; 940) and the reference of a particular body element (10, 20, 30; 141; 806; 940) has a known spatial relation to the particular body element (10, 20, 30; 141; 806; 940). The system comprises a plurality of reference frames (116; 122; 200; 302; 400; 900; 956), at least one attached to each of the movable body elements. It also comprises a localizer (108; 136; 1100) for identifying, during the procedure, the position of the reference for each of the body elements (10, 20, 30; 141; 806; 940) to be displayed, as well as a processor (104; 1108) for modifying the image data set (106) according to the identified position of the reference during the procedure, as identified by the localizer (108; 136; 1100), said processor (104; 1108) being adapted to generate an image data set (122) representing the position and geometry of the body elements (10, 20, 30; 141; 806; 940) according to the identified position of the reference frames during the procedure, as identified by the localizer. Also included in the system is a display (124; 1106) utilizing the displaced image data set (122) generated by the processor (104; 1108), illustrating the position and geometry of the body elements (10, 20, 30; 141; 806; 940) during the procedure.
Abstract:
A method for planning a procedure using a navigation system (100), comprising receiving image data (402) of a patient; receiving a three-dimensional trajectory of an object outside a space of the image data of the patient; determining with the navigation system a position of a first representation of a first trajectory (415a-d) of the object relative to the image data; determining with the navigation system a position of a second representation of a second trajectory (415a-d) of the object relative to the image data; storing the first trajectory, the second trajectory, or combinations thereof; superimposing the first representation and the second representation onto the image data; and calculating a measurement between the first trajectory and the second trajectory.
