Abstract

The first few years of any new imaging technology are characterized by rapid developments in equipment. Digital subtraction angiography (DSA) is no exception. These improvements must be accompanied by an increase in understanding of the interaction between equipment and the patient. Several articles have discussed the impact of various components on the signal to noise ratio (SNR). While most users have recognized the importance of certain biological factors, e.g. heart rate, cardiac output, etc., only recently has the equipment evolved to the state permitting systematic study of these variables.
