1. A method of preparing an image acquisition by an imaging system in a patient comprising:
a. tracking one or more components of the imaging system in real time, wherein the imaging system uses ionizing radiation;
b. obtaining, by at least one computer processor, information about a geometry of the one or more components of the imaging system, information about a geometry of the image acquisition, information about one or more image acquisition parameters, or a combination thereof;
c. generating, by the at least one computer processor, a 3D representation of a surface, a volume or combination thereof, wherein the 3D representation of the surface, the volume or combination thereof is at least in part derived from the information about the geometry of the one or more components of the imaging system, information about the geometry of the image acquisition, information about the one or more image acquisition parameters, or combination thereof;
d. generating, by the at least one computer processor, an augmented view, the augmented view comprising the 3D representation of the surface, volume or combination thereof;
e. displaying, by an augmented reality display device, the augmented view onto the patient at a position and orientation relative to the one or more components of the imaging system;
f. updating in real time the position and orientation of the augmented view based on real time tracking information of the one or more components of the imaging system so that the 3D representation is maintained in relationship to the one or more components of the imaging system as the imaging system moves; and
g. acquiring the image of the patient,
wherein steps a. through f. are before the step of acquiring the image of the patient.
