Abstract
A system and method for a procedure that can be performed on an appropriate subject. Procedures can include assembling any appropriate work piece or installing members into a work piece, such as an airframe, autoframe, etc. Regardless of the subject, generally the procedure can have a selected result that is efficacious. The efficacious result may be the desired placement of a device. The system and method can be used in confirming an efficacious result.
Claims17
A method of identifying a position of a member with image data acquired with an imaging device, comprising:
- acquiring confirmation image data of the portion of interest after a member is placed in a subject;
- determining a position of the member within the acquired confirmation image data;
- recalling a model of the placed member;
- recalling a prior image data of the subject including the portion of interest;
- superimposing a graphical representation representing the member based at least on the recalled model of the placed member on an image model generated with recalled prior image data;
- and
- displaying the image model with the superimposed graphical representation.
A system to identify a position of a member with image data acquired with an imaging device, comprising:
- a processor system configured to execute instructions to:
- evaluate a confirmation image data of a portion of interest of a subject acquired with the imaging device,
- recall a model of the member;
- and
- determine a position of the member based on the confirmation image data of the portion of interest of the subject;
- recalling a prior image data of the subject including the portion of interest;
- determine a position to superimpose a graphical representation representing the member based at least on the recalled model of the member on an image model generated with the recalled prior image data;
- and
- a display device configured to display the graphical representation representing the member superimposed on the image model;
- wherein the prior image data is acquired prior to the confirmation image data;
- wherein the image model is based at least on the prior image data.
The system of claim 15, further comprising:
- a tracking system configured to track a first tracking device associated with the imaging device and a second tracking device associated with the member;
- wherein the processor system is configured to execute further instructions to evaluate the tracked position of the member relative to the confirmation image data to at least assist in determining the position of the member in the confirmation image data.
The system of claim 16, wherein the processor system is configured to execute further instructions to register the prior image data to the confirmation image data.
