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.2/3 ACTIVE X-RAY CONTROL 53 GENERATE REAL IMAGE. -55 DISPLAY REAL IMAGE GENERATE 57 SIMULATED IMAGE SWITCH COLLIMATOR 63 COMPARE SWITCH OFF.
