Abstract
Medical imaging is carried out by transmitting X-ray emissions through a subject, generating a first set of temporally separated images of an area of interest in the subject from the transmitted X-ray emissions, generating a second set of temporally separated images from the area of interest from a second source, and combining the sets to produce combined images of the area of interest. The method is further carried out by blocking the X-ray emissions from reaching the subject, updating the second set, combining the first set with the updated second set to produce updated combined images, displaying the updated combined images, and when a predetermined condition is satisfied, iterating updating the second set, combining the first set with the updated second set, and displaying the updated combined images.
