A method and system are providing for performing X-ray diagnostic imaging using a camera image controlled to image a field of view (FOV) that is substantially coincident and coplanar with a radiation footprint or FOV of an X-ray beam radiated towards a patient under examination. Both the X-ray beam and camera FOVs are shaped and/or limited by collimation. The method and system include acquiring a camera image with a collimated FOV to an X-ray beam FOV before X-ray imaging a patient, displaying the camera image and adjusting the collimation and patient positioning to define the X-ray beam FOV based on the displayed camera image before X-ray imaging the patient. After adjustment, the method and system include radiating the X-ray beam as collimated during the patient X-ray imaging, acquiring and processing captured X-ray image information to reconstruct an X-ray image and displaying the reconstructed X-ray image with the displayed camera image. The step of radiating may be postponed or interrupted for X-ray beam readjustment or patient repositioning for desired X-ray imaging based on the camera image displayed.
