Abstract
A system and method for a procedure that can be performed on an appropriate subject. A procedure may be planned, at least in part, prior to performing the procedure. An image may illustrate at least a portion of the planned procedure for confirmation and/or alteration of the planned procedure prior to performing the procedure.
Claims17
A method of at least one of planning or confirming at least a portion of a planned procedure on a subject with image data acquired with an imaging device, comprising:
- acquiring the image data with the imaging device at a selected position relative to a portion of interest to acquire the image data of the subject;
- selecting a planned entry point into the subject on an image generated with the image data;
- selecting a trajectory to a target within the subject on the image;
- displaying a boundary icon representing a boundary of possible trajectories achievable with a guide member on the image at the planned entry point;
- displaying a guide icon of the guide member superimposed on the image at the planned entry point;
- displaying a selected trajectory icon representing the selected trajectory relative to the superimposed boundary icon of the guide member on the image;
- wherein the displayed selected trajectory relative to the super imposed boundary icon of the guide member may be used to determine if the selected planned entry point or the guide member are possible to achieve the selected trajectory of an instrument;
- wherein displaying the guide icon of the guide member includes displaying a line representing a base of the guide member and a pair of parallel lines representing an access portal for the guide member to illustrate dimensions through which the instrument may pass along the selected trajectory.

A method of planning a procedure, comprising:
- displaying an image of a subject;
- selecting an initial entry point on the image;
- superimposing a first guide device icon representing a first guide device at the selected entry point on the image;
- superimposing a first boundary icon extending from the superimposed first guide device icon on the image representing a first boundary of possible trajectories to be guided with the first guide device;
- superimposing a trajectory icon of a planned trajectory from the selected entry point to a selected target on the image;
- viewing the trajectory icon relative to the first boundary icon to determine whether the planned trajectory is reachable with an instrument, and superimposing an instrument icon of the instrument relative to the first boundary icon and trajectory icon;
- moving the first guide device icon so that a line of the first guide device icon representing a base of the first guide device is substantially adjacent a surface in the image;
- wherein the first guide device icon is superimposed including the line and a pair of parallel lines;
- wherein the pair of parallel lines are both perpendicular to the line and used to define a volume of the first boundary icon.
6 more elements
A system for planning a procedure, comprising:
- a memory system configured to store a guide device icon of a guide device and a boundary icon configured to illustrate boundaries of reachability of an instrument guided by the guide device;
- a processor system configured to execute instructions to:
- access image data,
- instruct the display device to display an image based on the image data,
- receive input from a user input to instruct a display device to display a first selected trajectory icon, and
- receive input from the user input to instruct the display device to superimpose the guide device icon and the boundary icon on the displayed image at a selected initial entry point;
- wherein a user is able to view the display device to view the first trajectory icon relative to the device icon and the boundary icon to determine whether a first planned trajectory is reachable with the instrument guided by the guide device;
- wherein the user input is configured to be engaged by the user to move the guide device icon so that a line of the guide device icon representing a base of the guide device is substantially adjacent a surface in the image;
- wherein the guide device icon includes the line and a pair of parallel lines;
- wherein the pair of parallel lines are spaced apart and both perpendicular to the line and used to define the boundary icon.
