Abstract
In an interventional radiography (IVR), for example in a percutaneous transluminal coronary angioplasty (PTCA), when the IVR includes a period in which the movement of the object is slow, a normal X-ray radiating mode (a continuous X-ray radiation or a normal rate pulse radiation of about 15-30 pulses per second) is changed to a very slow rate pulse X-ray radiation of about 1-5 pulses per second to decrease the X-ray dose of the patient. Since the movement is slow, the very slow rate pulse radiation can still trace the movement adequately. Further, the quality of the X-ray image is improved by increasing the tube current in the very slow rate pulse radiation because less heat is generated in the X-ray tube.
