System and process of utilizing image data to place a member
Disclosed is a system for acquiring and using image data and generating a three-dimensional reconstruction of a subject. The three-dimensional reconstruction can be used to assist in determining various features, including axis and planes of a subject or members placed relative to the subject. The system can be implemented to plan and perform a procedure relative to the subject.

determine at least one anatomical landmark of the subject in the three-dimensional image reconstruction of the subject;
determine a geometric configuration representative of a portion of the subject based on the three-dimensional image reconstruction of the subject and the at least one anatomical landmark;
display an icon of the at least one anatomical landmark and the geometric configuration superimposed on the three-dimensional image reconstruction of the subject, where the geometric configuration is at least one of an anatomical plane icon or an anatomical angle icon; and

display an icon of the at least one anatomical landmark and the geometric configuration superimposed on the three-dimensional image reconstruction of the subject, where the geometric configuration is at least one of an anatomical plane icon or an anatomical angle icon, and
determine a similarity between the actual post-procedure condition of the subject to at least one predetermined desired post-procedure configuration of the subject; and
an output device configured to display for viewing the determined similarity.
11. The system of claim 10 , wherein the processor is configured to execute further instructions to:
access a pre-procedure x-ray image data of the subject,
determine the at least one anatomical landmark in a first three-dimensional image reconstruction based on the accessed pre-procedure x-ray image data of the subject, and
determine a pre-procedure geometric configuration representative of at least the portion of the subject.
12. The system of claim 10 , wherein the processor is configured to execute further instructions to recall the predetermined desired post-procedure configuration of the subject based on the three-dimensional image reconstruction of the subject representing an actual post-procedure condition of the subject.
13. A method for using an x-ray imaging system with a procedure, the method comprising:
operating a processor to execute instructions to automatically (i) generate a first three-dimensional image reconstruction of a subject based on projections from a first x-ray image data set, (ii) determine at least one anatomical landmark in the first three-dimensional image reconstruction, and (iii) determine a first geometric configuration of a portion of the subject based on the at least one anatomical landmark;
acquiring projections from a second x-ray image data set after at least a portion of the procedure;
operating the processor or a second processor to execute further instructions to automatically (i) generate a second three-dimensional image reconstruction of the subject based at least on the projections of the second x-ray image data set, (ii) determine the at least one anatomical landmark in the second three-dimensional image reconstruction, and (iii) determine a second geometric configuration of the portion of the subject based on the at least one anatomical landmark;
