Image data acquisition, processing, storage and display.
It is important to optimize each stage of image formation to minimize and take the greatest advantage of X-ray dose used. For each stage (acquisition, processing, and display) an optimum exists within the limits of physical laws and current technology. These laws must be understood and the technologic limitations imposed by them appreciated to acquire the maximum information from digital subtraction angiography (DSA) examinations.
