[Contrast dose and signal/noise ratio in digital angiography].
In a digital angiographic system the variations of the signal to noise ratio in relation to the contrast medium quantity and to the exposure data are analyzed. On these basis, the greater flexibility of the digital angiographic equipments in comparison with conventional ones is underlined.
