Recently, digital subtraction angiography (DSA) is seeing widespread use. Especially, intra arterial DSA (IA-DSA) makes good use of interventional radiology. However, we know that the skin dose for DSA is so much larger than general angiography, and halations often appearing on DSA images. In this report, we show two improvements of DSA. First, the skin dose for DSA is successfully decreased to one-sixth compare with the late DSA of cerebral artery by a reduction in acquisition images. Secondly, we are doing well in suppressing halation by exchanging the control point of automatic exposure control (AEC) from one-half to one-fourth.
