Recently, the tasks of the radiological technologists have the difference between hospitals. Angiographic equipments have been improved performance, as results, they are enhanced convenience and their operations are advanced automation. However, there are difficult to understand to change the tasks for the radiological technologists. In some hospitals, they are reduced, that are not associated with the angiography. On the other hands, the irradiated doses are more than ten times the gap in angiography at various hospitals. We, therefore, need to discuss that the irradiated doses will be optimized at them. Since they have been changed over from diagnostic procedures to be therapeutic interventional procedures in the examinations, the x-ray fluoroscopy has been extended long period and number of times radiography has been increased. There are also made complicated to be therapeutic interventional procedures by developments of new devices and improvement of their operations. It is clear that these complications are the serious problems by exposure dose. In this paper, we discuss about role sharing of the radiological technologists on advanced digital angiography.
