1. A method for automatically aligning images obtained while performing a DXA imaging procedure of an object, the method comprising the steps of:
a. providing a DXA imaging system comprising:
i. a support on which an object to be imaged is adapted to be positioned;
ii. a radiation source movably disposed relative to the support and configured to emit radiation beams towards the object;
iii. a detector movably disposed relative to the support and aligned with the radiation source to receive the radiation beams from the radiation source and generate image data;
iv. a controller operably connected to the radiation source and the detector to control the movement and operation of the radiation source and detector, the controller configured to receive and process image data from the detector;
v. a display operably connected to the controller for presenting information to a user; and
vi. a user interface operably connected to the controller to enable user input to the controller
b. positioning the object on the support;
c. operating the radiation source and the detector to obtain at least one image of the object;
d. determining an offset of the at least one image relative to an image reference; and
e. aligning the at least one image with the image reference.
