Primary outcome measure(s)
The radiation dose received by patients during interventional procedures when using two scanning protocols (classic 3D-DSA and PS-3D-DSA) — No more than 6 hours Using the built-in radiation monitoring function of interventional surgical equipment (DSA system), the radiation dose (AK，air kerma) received by the patient during the procedure is directly measured and recorded. The collected radiation dose data is documented in the patient's medical records and stored in the research database for subsequent analysis and comparative studies.
