Disclosed is a method for obtaining digital subtraction angiography (DSA) images using a dynamic frame rate. The method dynamically adjusts frame rates in response to motion artifacts during DSA image acquisition. In situations where there is a high degree of motion, the frame rate can be optimized to increase image quality. On the other hand, in situations where there is a low degree of motion, the frame rate can be lowered to limit the radiation exposure to the patient and provider without overly sacrificing image quality.
